In this paper, a standalone patch antenna operating at 2.3 GHz is initially designed as a reference antenna. Subsequently, the patch antenna is incorporated with an Artificial Magnetic Conductor (AMC) as the ground plane to obtain an Antenna with Artificial Magnetic Conductor (AAMC). Performance comparison is analyzed between the standalone patch antenna and the AAMC. The incorporation of AMC to the patch antenna successfully enhances the bandwidth of the standalone patch antenna by 520%, increases gain by 2dBi, and boosts the efficiency up to 30 % as compared to the reference antenna. As a result of the bandwidth enhancement, the AAMC is capable to cover several frequency bands within 2.19 GHz to 2.5 GHz. Hence, the new design is suitable for WiMAX, WLAN and RFID applications. The measurement results in terms of return loss, gain and radiation patterns agreed satisfactorily with the simulated ones. Moreover, the parametric studies of antenna dimensions and air gap are presented and discussed.

Microstrip Patch

In this paper, Microstrip patch antennas with rectangular and swastika shape of patch are designed and its performance parameters are compared with each other. Rectangular and Swastika shaped patch are considered in this paper with common rectangular ground plane. The antenna is simulated at 2.4 GHz using HFSS simulation software. This work mainly includes modification of antenna patch to improve the antenna parameters. The parameters of antenna such as Return loss, VSWR Bandwidth and radiation pattern are compared using simulation. The performance of Swastika shaped antenna was found to be better than rectangular shaped microstrip patch antenna with improved Return Loss, VSWR, Bandwidth and Radiation Pattern.

Phase Reflection

To improve the antenna characteristics in terms of bandwidth, gain and its radiation characteristics without providing any phase reflections, Artificial Magnetic Conductor (AMC) are used in antenna designing. This paper initially designed AMC structure for 2.4GHz frequency. The proposed AMC structure consists of three L shaped and inverted L shaped slots and provides zero degrees phase reflection at 2.4GHz resonant frequency. This proposed AMC structure is incorporated on conventional micro strip square patch antenna and results are simulated in High Frequency Structure Simulator (HFSS) software. The Proposed AMC incorporated patch antenna, return loss is improved from -16.16dB to -31.75dB, VSWR is from 1.42 to 1.05, the band width is increased from 16.5 MHz to 348.1 MHz This design resonates at a frequency of 2.4GHz and applicable to Wi-Fi applications.

Rectangular Microstrip Patch Antenna

<p>This paper presents the bandwidth enhancement of a Proximity Coupled Feed Rectangular Microstrip Patch Antenna using a new Defected Ground Structure - an ‘inverted SHA’ shaped slot on the ground plane of the proximity coupled feed rectangular Microstrip patch antenna. The parameters such as Bandwidth, Return loss, VSWR and Radiation efficiency are improved in the proposed antenna than simple proximity coupled feed rectangular Microstrip patch antenna without Defected Ground Structure. A comparison is also shown for the proposed Microstrip patch antenna with the antenna structure without Defected Ground Structure. The proposed antenna resonates in S-band at frequency of 2.4 GHz with bandwidth of 180 MHz. A very good return loss of -47.9223 dB is obtained for the Microstrip patch antenna with an ’inverted SHA’ shaped Defected Ground Structure. Implementing an ‘inverted SHA’ shaped defect in the ground plane of the proximity coupled feed rectangular Microstrip patch antenna results in 5.3% improvement in bandwidth with 16.01% reduction in the overall area of the ground plane as compared to the Microstrip patch antenna without Defected Ground Structure.</p>

This paper presents a simple broadband planar monopole microstrip patch antenna with curved slot and partial ground plane. The proposed antenna is designed and fabricated on commercially available FR4 material with εr = 4.3 and 0.025 loss tangent. Bandwidth enhancement has been achieved by introducing a curved slot in the patch and optimizing the gap between the patch and the partial ground plane and the gap between the curved slot and the edge of the patch. Simulated peak gain of the proposed antenna is 4.8 dB. The impedance bandwidth (defined by 10 dB return loss) of the proposed antenna is 109% (2–6.8 GHz), which shows bandwidth enhancement of 26% as compared with simple monopole antenna. The antenna is useful for 2.4/5.2/5.8-GHz WLAN bands, 2.5/3.5/5.5-GHz WiMAX bands, and other wireless communication services. Measured results show good agreement with the simulated results. The proposed antenna details are described and measured/simulated results are elaborated.

A broadband circularly polarized stacked probe-fed antenna suitable for UHF RFID applications is presented and studied. The proposed antenna is fed by two probes which are connected to a hybrid coupler. Two parasitic patches are stacked above a primary probe-fed patch to enhance the bandwidth of the antenna. The optimized antenna prototype achieves gain of more than 6.5 dBic, axial ratio of less than 3.0 dB, and return loss of less than−15 dB over the UHF band of 820–980 MHz (17.7%). Parametric studies are carried out to demonstrate the effects of antenna geometry parameters on the performance. The proposed antenna can be a good candidate for UHF RFID applications.
