Performance analysis of microstrip patch antenna for wireless communication systems

<p>An antenna may be thought of as a temporary tool that directs radio waves for transmission or reception. Aside from being inexpensive, small, easy to manufacture, and compatible with integrated electronics, the microstrip patch antenna (MPA) offers several other benefits as well. These two methods are often seen as low-cost, adaptable, dependable, high-speed data connection choices that promote user mobility. An overview of how MPA have been used throughout the last several decades is provided in this article. It has been suggested that there are many approaches to enhance the performance of MPA, including the use of composite antennas, highly integrated antenna/array and feeding networks, operating at relatively high frequencies, and using cutting-edge manufacturing methods. Dual or multiband antennas are essential for meeting the demands of wireless services in this rapidly evolving wireless communication environment. Here is an overview of the patch antenna literature for wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications.</p>

Design and Analysis of Microstrip Patch Antenna for Space and Wireless Communication

Abstract: This paper aims to provide a comprehensive overview of the design of microstrip patch antennae since communication and connectivity are two very important aspects of mankind. For ages, antennas have been highly demanded transducers in communication technology. With the development of the technologies in today’s era, wireless systems are becoming more compact, thereby reducing the size of the antenna. As space research is taking huge leaps, even private companies like Space X and ambitious projects from ISRO and NASA have been introduced. Space research motivates researchers to carry out more studies about space bodies that produce radio waves. Detection of the position and velocity of bodies using radar provides emerging research into this domain, which is called radio location. Therefore, multiband antennas are explored to obtain multiple operating frequencies. The reduced size, low profile, and lightweight microstrip antennas have become integral to wireless communication systems, and the increasing growth of wireless systems requires a miniaturized antenna. Thus, this paper discusses the basic configuration of MPA (Microstrip Patch Antenna), its feeding techniques, and different shapes in CST (Computer-simulated technology) microwave studio, dielectrics, and substrate materials. The paper also provides an overview of wireless applications, such as radar systems, satellite communication, and military applications. Also, there is a description of how to design a microstrip antenna in MATLAB.

Design and analysis of microstrip patch antenna for RADAR altimeter

The most important parameter for any flying vehicle is altitude. Different techniques and methods are available for altitude measurement; one of these methods is RADAR Altimetry. In this technique altitude measurement of an in-flight vehicle is measured by using RF waves and RADAR. RADAR Altimeter transmits low-power radio waves, these waves incident on the earth and get reflected back with a shift of about 40 Hz/feet. The altitude is determined as per the time delay between the signals which is measured by differentiating the broadcast and received signal for a specific time period. The RADAR altimeter operates on a frequency range of 4.2 to 4.4 GHz in the C-Band. Different shapes of microstrips are tested and used for this application. In this article, a rectangular microstrip antenna is designed and simulated at 4.2GHz and its performance and characteristics are analysed using ANSYS HFSS.

Due to lower latency, greater transmission speed, wider bandwidth, and the possibility to connect with greater multiple devices, fifth-generation (5G) networks are far better than 4G. In this study, a microstrip patch antenna operating at 28 GHz is investigated and modeled for future 5G communication technologies. The substrate used in this work for the antenna is Rogers RT/Duroid5880. Dielectric of the substrate is 2.2 and thickness is 0.3451 mm.

The result found from this simulation is better than the works took place in the past. As a result, it can be utilized as a capable candidate for 5G wireless technology. The results of this proposed antenna are superior to those of existing antennas published in recent scientific journals. As a result, it's likely that this antenna will meet the needs of 5G wireless communication systems.

Design and Analysis of Microstrip Patch Antennas for Narrow Band Communication Applications

Abstract- Microstrip antennas are low-profile antennas. A metal patch mounted at a ground level with a dielectric material in between constitutes a Microstrip or Patch Antenna. These are very low- size antennas having low radiation. The patch antennas are popular for low-profile applications at frequencies above 100 MHz, these antennas consist of a very thin metallic strip placed on a ground plane with a dielectric material in-between. Usually, the antennas are chosen to be circular or rectangular in shape for ease of analysis and fabrication. These antennas are employed at ultra-high frequencies and higher frequencies. This paper aims to design and analysis of microstrip patch antennas for Narrowband Communication Applications by the analysis on antenna parameters such as Voltage Standing Wave Ratio (VSWR), S11 Parameters, Radiation Pattern and Gain. Dielectric materials FR4 Epoxy, RT Duroid 5880, RT Duroid 6006 and RT Duroid 6010 are considered whose permittivity is 4.4, 2.2, 6.15 and 10.2. The antennas are simulated at 900 MHz frequency using Ansys Electromagnetic Suite (HFSS) software and the resultant graphical analyses of the parameters are plotted. The antennas are also fabricated with the above dielectric materials and are tested for practical values using a network analyser using Midas software. The results show that RT-Duriod 6006 gives better values when compared to the other substrate materials. The gain observed is 12.6 dB with a VSWR of 1.65. From the obtained results, it can be concluded that the antenna made from this substrate material (RT-Duriod 6006) are best suited for narrow band communication applications.

Empirical analysis of microstrip patch antenna for different substrate materials and shapes using aperture coupled technique

The dielectric material used as a substrate and the shapes of the patches play an important role in the performance of bandwidth, return loss, and gain of the microstrip patch antenna. This paper presents the relative study of different shapes of microstrip Patch antenna for different dielectric materials. The main application of these antennas is for satellite communication in Ku-Band. The height of the substrate plays an essential role in the enhancement of bandwidth and it is chosen 1.012mm and three substrate materials (RT Duroid (5880), Teflon, and FR4) with different dielectric constants were chosen for the performance comparison. Aperture coupling, which is again one of the promising techniques for bandwidth enhancement, is used as a feeding technique for the designs. Coupling must be taken care of while using aperture coupling, which is done by precisely optimizing the feed line dimensions, feed position, slot dimensions, and patch dimensions. The antenna performance is studied by varying the parameters like patch, feed line, and slot dimensions, the size of the substrate, and the feed line position concerning the slot. Optimization is also performed for the position of the ground layer within the substrate material and the ground plane in the middle position of the substrate is chosen for the final designs. Return loss and impedance matching were analyzed for all designs. The rectangular and circular patches are used for a comparative study, which is conducted from 12GHz to 14GHz out of which the circular patch is found to give better performance. The analysis is carried out for RT Duroid (5880) material and the bandwidth obtained in both cases is almost 3GHz. Similarly, the analysis is carried out for different dielectric materials over the frequencies of 12GHz to 14GHz in which RT Duroid and Teflon give better performance in terms of return loss and FR4 gives better performance in terms of miniaturization. The analysis is carried out for rectangular patches and the bandwidth obtained for FR4 is 1GHz whereas, for RT Duroid (5880) and Teflon, it comes out to be 3GHz. The results are depicted in various tabular and graphical formats. This study is conducted using an HFSS, an electromagnetic solver.

The radiation pattern that was modelled radiates in yz plane is symmetrical in both upward and downward and it is unidirectional in xz plane. The simulated specific absorption rate values are 0.0559 W/kg under 1 g standard and falls below the limitation of USA and Europe standard, which makes the design more suitable for wearable application with reliability.

Performance analysis of microstrip patch antenna using a four-layered substrate of different materials

Substrates of different materials have a significant role in the design of microstrip patch antennas due to their varying chemical, thermal, and physical properties. The authors of this research study proposed an examination into the performance of multi-band microstrip patch antennas mounted on multi-layered dielectric substrates such as FR-4, GaAs, polyethene, and plexiglass The primary goal of this study is to improve the performance of the proposed microstrip patch antenna in terms of return loss, bandwidth, gain, and power density by adding and stacking four different substrates of different material types with an equal dielectric substrate thickness of 1.8 mm, equal patch dimensions of 37 mm × 52 mm, and equal substrate dimensions of 50 mm × 80 mm. The results reveal that adding and stacking substrates of different material kinds improves the performance of the proposed microstrip patch antenna. Moreover, there is a shift in resonance frequencies as well as a shift in beams, operating as a smart antenna. Further study has been undertaken by loading metamaterial-based split-ring resonators on the proposed patch and the ground plane to improve performance. The proposed antenna is extremely useful for electronic communication systems that employ WLAN/Wi-Fi.

Comparative Analysis of Microstrip Patch Antenna of Wearable IOT Devices for Health Care

The Advances in the biomedical applications demands an antenna having highefficiency and gain, low return losses and Specific Absorption Ratio (SAR) to beassociated with the wearable and implantable devices for the accurate data transferwithout any data drift. For this, multi-band MIMO (multi-input multi output)applications, the antenna design with the target parameters is a challenging task toestablish a rich and reliable wireless communication setup with the monitoring systemin SHM of both biomedical and industrial sectors. Higher SAR will create the hazardsto the human body. The gain of the antenna and return loss figures depends on thesignal loss in the human tissues. Another important design challenge is the antennasize, which should be convenient to carry. Usually, Micro strip patch antenna is usingfor such type of applications as it satisfies most of the design parameters. But thebandwidth and gain of MSP are very limited. Hence there is huge scope to enhancethe gain and bandwidth of the micro strip patch antenna to fit for the biomedicalinvasive applications. Artificial materials having negative permittivity andpermeability will yield a negative refractive index will do better than the existingmaterials in the antenna design for the ISM band(2.45-5.8GHz) and satellites (11-13GHz).

An Insight into Impact of Partial Ground and Dual Trapezoidal Slots on Bandwidth and Gain considerations for a Microstrip Antenna Array for WiMax Application

In this work, design and analysis of microstrip patch antenna is carried out. A (2 X 1) antenna array is considered, with dimensions (W x L) as 35.11 mm x 27.13 mm. The dielectric substrate is taken to be FR4 epoxy with dielectric constant as 4.3 and loss tangent of 0.02. Dual trapezoidal slots are introduced to improve the gain considerations for the considered antenna array. The simulations are carried out and it is observed that the gain is improved. As a second stage in the work, to improve the bandwidth of operation for the dual trapezoidal antenna array, the concept of partial ground is taken into consideration. The simulations are carried in HFSS. It is found out that the introduction of partial ground improved the bandwidth of the antenna structure considered while preserving the gain to the maximum extent possible. The gain was found to be 7.0875 dB with centre frequency 2.4020 GHz. The frequency range below -10dB for the considered antenna array structure with partial ground was around 2.3 GHz to 2.6 GHz. This range is utilized in the WiMax application which covers the frequency ranges (2.3 GHz to 2.4 GHz) and (2.496 GHz to 2.690 GHz).

Microstrip antenna analysis using the method of fundamental solutions

AbstractThe method of fundamental solutions (MFS) is proposed for the analysis of microstrip patch antennas of arbitrary shape. The MFS consists mainly in approximating the solution of a problem by a linear combination of known fundamental solutions associated with source points located outside the domain. The implementation of the MFS is simple and computationally efficient. Simulation results are obtained for rectangular, circular and triangular microstrip patch antennas. The resonance frequency and input impedance results are in good agreement with those published in the literature. Two prototypes have been fabricated and tested. Good agreement has been obtained between the MFS simulations and the experimental results. Copyright © 2008 John Wiley & Sons, Ltd.
