Compact Tri-Band Notched Characteristics UWB Antenna for WiMAX, WLAN and X-Band Applications

Compact microstrip-fed printed monopole antenna with triple band-notched characteristics is suggested for ultra-wideband (UWB) applications. The antenna is constructed of a conventional rectangular microstrip patch antenna with partial ground plane and T-shaped strip employed in the ground plane as well as an inverted Ω- and L-shaped slots incorporated within the radiated element. The notched functions are created by the inverted Ω- and L-shaped slots, which are realized for WiMAX (from 2.69 to 4.5 GHz) and WLAN (from 5.49 to 6.37 GHz). The T-shaped parasitic strip generates the third notch for the X-band uplink satellite communication (from 8.15 to 9.61 GHz). The measured operating -10 dB bandwidth of the proposed antenna extends from 2.39 to more than 18 GHz except at the notched bands. The prototype antenna has a total area of 20×20×1.6 mm3. Electromagnetic (EM) simulations are carried out using 3D full-wave FEM-based simulator. EM simulation results are in good agreement with measurement results. The radiation pattern of the proposed antenna is nearly Omni-directional over the whole targeted band.

Design and implementation of dual-band antennas based on a complementary split ring resonators

A simple dual-band antenna design and implementation method is proposed in this work, based on the equivalent media properties inspired by resonant metamaterial elements. The equivalent circuit model of dual-band patch antennas based on a complementary split ring resonator (CSRR) is presented and validated. The dual-band patch antenna is designed etching a CSRR in the patch of a conventional rectangular microstrip patch antenna. The first resonance is governed by the quasi-static resonance of the CSRR while the second resonance is originated by the rectangular patch. The fact of etching a CSRR on a rectangular patch antenna also produces a miniaturization of a conventional patch antenna. The equivalent circuit model proposed in this letter is sound in order to understand the functionality of dual-band patch antennas based on a CSRR. Good agreement between simulation, equivalent circuit model and experimental results is shown and discussed. These results lead the equivalent circuit model to become a simple and straightforward tool for the design of this type of multiband antennas, of low cost and versatile operation for a broad range of wireless communication systems.

The proposed antenna consists of C-shaped slot incorporated in ground plane which resonates at two different frequencies (fr1 and fr2) of 7.41 GHz and 9.28 GHz which lie in C-band and X-band respectively. A very good return loss (S11) of -30.79 dB and -40.75 dB are obtained at first and second resonant frequencies respectively for C-shaped DGS antenna. The Bandwidth of C-shaped DGS antenna is increased by 825 MHz and 1182.8 MHz respectively at two different bands than the bandwidth of the Conventional Rectangular Microstrip Patch Antenna (CRMPA). Also VSWR is much improved with C-shaped DGS antenna. The comparison of simulated results of proposed and CRMPA has also been presented in this paper.

Compact microstrip antenna for mobile communication

A single layer, single feed compact rectangular microstrip antenna is proposed. Resonant frequency has been reduced drastically by cutting unequal rectangular slots at the edge of the patch. Two rectangular slots are introduced at the left and right side of the patch to reduce the resonant frequency. The widths of the rectangular slots are different to improve the gain bandwidth performance of the antenna. The antenna size has been reduced by 73.9% when compared to a conventional rectangular microstrip patch antenna. The characteristics of the designed structure are investigated by using Method of Moment-based electromagnetic solver, IE3D. There is a reasonable agreement between these simulated data and measured values. An extensive analysis of the return loss, radiation pattern, gain, and efficiency of the proposed antenna is shown in this paper. The simple configuration and low profile nature of the proposed antenna leads to easy fabrication and make it suitable for the applications in Wireless communication system.

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> A novel compact design for UWB planar monopole antenna is presented in this letter. The basis for achieving the UWB operation is through using semicircular microstrip monopole antenna with circular modified ground plane. This shape produces bandwidth ranging from 3 to 35 GHz with discontinuities in certain bands from 7 to 10 GHz and from 12.5 to 17.5 GHz. The antenna size is around 27% of the size of a conventional rectangular microstrip patch antenna. Electromagnetic band-gap (EBG) structures are used for further improve the antenna performance. It is shown that by embedding metallo-EBG structure (MEBG) such as circular and square patches, it is possible to eliminate ripples in the operating band and still achieve a reduction in the antenna size to more than 60% from conventional patch. The final antenna design provides an impedance bandwidth (S11 $&lt;{-}10$ dB) of more than 33 GHz with averaged radiation efficiency of 73%74% and antenna gain of 6.5 dBi. </para>
