Modeling the effect of bend radius on the performance of a conformal dual-band mm-wave patch antenna array

There is growing interest in the use of additive manufacturing for the fabrication of RF devices due to fast prototyping capabilities and the use of less material as opposed to traditional fabrication techniques. In addition to the previously mentioned advantages, the aerosol jet printing method in particular allows for the conformal printing of RF components. This work models the effect of the bend radius on the return loss and radiation pattern of a dual-band (28 GHz and 39 GHz) mm wave patch antenna array design that will be aerosol jet printed. The antenna is modeled on a 5-mil thick flexible substrate (PET) and the simulation is run from 27 GHz to 40 GHz using HFSS. The return loss and radiation pattern results of the antenna are compared for various bend radii (0.25 in to 2 in) of the conformal surface the antenna is to be printed upon. Simulation results show a maximum frequency deviation of about 400 MHz on the return loss for the low (28 GHz) frequency band of the antenna when it is bent from a bend radius of 0 in to 2 in.

New circularly polarized microstrip patch antenna array design for energy harvesting applications

This paper gives an essential contribution to the energy engineering topic, especially the energy harvesting field. Wireless power transmission (WPT) is one of the most widely used methods in this field recently to generate electricity in a clean way for the environment like the rectenna systems. The main component of the rectenna systems is the microstrip patch antenna (MPA). This is the main reason why this article proposes a novel conception of 1×4 circular polarized MPA array to operate in the industrial, scientific, and medical (ISM) band at the resonant frequency of 2.45 GHz for radio frequency energy harvesting (RFEH) systems. The basic MPA element is a square antenna using a center slot and V-slits at the four corners combined with a defected ground structure (DGS) method. This proposed conception is developed in order to improve the antenna’s performance to integrate with a rectifier circuit for the Rectenna systems which are the most used systems in RFEH. The simulation results obtained by CST MWS software and HFSS solver show that this novel design in this paper gives good performances in terms of the reflection coefficient, voltage standing wave ratio, axial ratio, directivity, and gain at 2.45 [GHz]. This developed MPA is suitable for various RFEH applications.

28 GHz Patch Antenna Array with Reduced Mutual Coupling for 5G Communications Systems

A 28 GHz patch antenna array with reduced mutual coupling for 5G communication systems is presented in this paper. Two elements antenna array was simulated with a periodic boundary to represent an infinity array. The antenna array is attached with a pair of the coupled directional coupler with a coupling value of -3.47 dB, and transmission lengths of 3.40 mm and 7.62 mm depending on the antenna array's magnitude and phase coefficient were designed and simulated. A reduced mutual coupling of -31.86 dB compared to -10.75 dB for an array without a decoupling network was observed. The wide scanning angle of ±180o was also achieved. These results were obtained under smaller antenna elements interspacing of 0.43 0. Moreover, the proposed antenna array design achieved a 3.32 GHz enhanced fractional bandwidth which is 11.8%. Generally, this work found that the combinatorial advantages of using the gap coupled insert feed technique and employing a pair of directional couplers develop the patch antenna array design with better performance.

Design and development of a graphene-based reconfigurable patch antenna array for THz applications

Abstract This paper presents a graphene-based antenna array for terahertz (THz) applications. The suggested antenna array has four radiating square shaped patches fed by a coplanar waveguide (CPW) technique. The proposed antenna array operates at the three frequencies with operational bandwidths of 1.173–1.210 THz (at 1.19 THz), 1.270–1.320 THz (at 1.3 GHz), and 1.368–1.346 THz (at 1.4 GHz). The total area of the antenna array is reported as 1000 × 1000 µm2, printed on a Silicon substrate with a thickness of 20 µm and a dielectric constant of ϵ r = 11.9. To enhance the structure’s performance and optimize the feeding network, a parametric analysis was performed using the FDTD technique. Furthermore, the key properties of the proposed antenna array, such as resonance frequency, peak gain, and radiation efficiency, may be changed by adjusting the chemical potentials of the graphene in the antenna array. The use of graphene’s chemical potential tuneability yields exceptional results comparing to the recent research outputs, with a peak gain and radiation efficiency of 10.45 dB and 70%, respectively. These results show the performance of the suggested design for constructing antenna arrays for use in THz applications.

This work presents a compact (125 mm diameter) wideband four-element antenna array with a high isolation level for Global Navigation Satellite System (GNSS) anti-jamming applications. The array consists of four identical right hand circularly polarized (RHCP) single feed rectangular patch antennas that can cover BeiDou B1 band (1559.05 – 1563.15 MHz), GPS L1 band (1563 – 1587 MHz), Galileo E1 band (1559 – 1591 MHz), and GLONASS G1 band (1593 – 1610 MHz). The proposed array has a wide frequency bandwidth of 100 MHz (1.55 – 1.65 GHz) with an axial ratio of less than 3 dB. The patch antenna elements are designed on a substrate that has a high dielectric constant to achieve a compact size. The size of each patch element is only 32 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\times 32\times5.08$ </tex-math></inline-formula> mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> . These patches are placed along the circumference of a circular aluminium ground plane of 125 mm diameter and 1.5 mm thickness in a <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$2\times 2$ </tex-math></inline-formula> symmetrical arrangement. The edge-to-edge distance between the opposite patch elements is only 48 mm while for the adjacent elements the separation is only 27 mm. A microwave absorber material is employed to achieve an extremely low mutual coupling level over a wide frequency range (1.55 – 1.65 GHz) within a compact form factor. The proposed design achieves a mutual coupling of less than −20 dB within a compact overall form factor of 125 mm diameter over the entire band of interest. The simulated and measured results of reflection coefficient, mutual coupling, null steering, null depth, and radiation pattern show that the proposed antenna array is an excellent choice for multiband GNSS applications.

Rectenna Design for Enhanced Node Lifetime in Energy Harvesting WSNs

In a scenario where every possible solution is investigated for sustainability, Energy Harvesting (EH) stands as an undisputed candidate for enhancing the network lifetime in WSNs where node lifetime decides the network’s life. Radio Frequency (RF) energy is abundantly available in the ambience among all the available energy sources. Since both information and power are transmitted in an RF signal, EH is possible in the far-field region. At first, we present a novel 4-element rectangular Patch Antenna Array (PAA) design of EH rectenna. The receiving antenna is designed to pick up the radio signal in the RF range (2.45 GHz) from the free space. Then, the H-shape antenna is modified by introducing a circular slot to enhance the bandwidth. The paper compares the results of the basic parameters of the antenna, such as return loss, input impedance, bandwidth, gain, directivity, and efficiency. As a result, the modified H-shaped antenna (with circular slot) has an increased gain from 8.24 dB to 8.32 dB, with a reduced return loss from -10 dB to -16 dB and enhanced bandwidth from 64.8 MHz to 868 MHz. The high gain, large bandwidth, suitably matched impedance for a minor return loss, and high efficiency of the modified H-shaped patch antenna makes it eligible for energy harvesting application.

PurposeThe purpose of this study is to achieve the low-cost, light-weight and compact antenna array with wide bandwidth and low side lobe levels for synthetic aperture radar (SAR) applications in Ku frequency band.Design/methodology/approachA compact design of a rectangular microstrip patch antenna array using multilayered dielectric structure is presented in Ku-band for advanced broadband SAR systems. In this design, stepped pins are used to connect the microstrip feed lines to the radiating patches.FindingsThe simulation and fabrication results of the multilayered antenna and a 1×16-element linear array of the antenna with Taylor amplitude distribution in the feeding network are presented. The antenna element has a 10-dB impedance bandwidth of more than 26%, and the linear array shows reduction in bandwidth percentage (about 15.4%). Thanks to Taylor amplitude tapering, the side lobe level (SLL) of the array is lower than −24 dB. The maximum measured gains of the antenna element and the linear array are 7 and 19.2 dBi at the center frequency, respectively.Originality/valueIn the communication systems, a high gain narrow beamwidth radiation pattern achieved by an array of multiple antenna elements with optimized spacing is a solution to overcome the path loss, atmospheric loss, polarization loss, etc. Also, wideband characteristics and compact size are desirable in satellite and SAR systems. This paper provides the combination of these features by microstrip structures.

Double Meander Dipole Antenna Array with Enhanced Bandwidth and Gain

In this paper, a new design of high gain and wide bandwidth microstrip patch antenna array containing double meander dipole structure is proposed. Two in-phase resonant frequencies in the Ku-band (12–18 GHz) could be achieved in the double meander dipole array structure, which lead to enhance impedance bandwidth without costing extra design section. Besides, further enhanced gain of 2 dBi of the array over the entire operating frequency range has been achieved by introducing a double-layer substrate technique. The proposed antenna has been fabricated using the E33 model LPKF prototyping PCB machine. The measurement results have been performed, and they are in very good agreement with the simulation results. The measured –10 dB impedance bandwidth indicates that the array provides a very wide bandwidth which is around 30% at the center frequency of 15.5 GHz. A stable gain with a peak value of 10 dBi is achieved over the operating frequency range. The E- and H-plane radiation patterns are simulated, and a very low sidelobe level is predicted. The proposed antenna is simple and has relatively low-profile, and it could be a good candidate for millimeter wave communications.
