Rectangular Microstrip Patch Antenna

<p>This paper presents Dual-Band proximity coupled feed rectangular Microstrip patch antenna with slots on the radiating patch and Defected Ground Structure. Initially a simple proximity coupled feed rectangular Microstrip patch antenna resonating at 2.4 GHz is designed. Etching out a ‘Dumbbell’ shaped defect from the ground plane and ‘T’ shaped slot from the radiating patch of the proximity coupled feed rectangular Microstrip patch antenna, results in a Dual-Band operation, i.e., resonating at 2.4 GHz and 4.5 GHz; with 30.3 % and 18.8% reduction in the overall area of the patch and the ground plane of the reference antenna respectively. The proposed antenna resonates in S-band at frequency of 2.4 GHz with bandwidth of 123.6 MHz and C-band at frequency of 4.5 GHz with bandwidth of 200 MHz, and a very good return loss of -22.1818 dB and -19.0839 dB at resonant frequency of 2.4 GHz and 4.5 GHz respectively is obtained. The proposed antenna is useful for different wireless applications in the S-band and C-band.</p>

<p class="Abstract"><span style="font-weight: normal;">In this paper a new geometry of patch antenna is proposed with improved bandwidth and circular polarization. The radiation performance of circularly polarized rectangular patch antenna is investigated by applying IE3D simulation software and its performance is compared with that of conventional rectangular patch antenna.</span> <span style="font-weight: normal;">Finite Ground truncation technique is used to obtain the desired results. The simulated return loss, axial ratio and smith chart with frequency for the proposed antenna is reported in this paper. It is shown that by selecting suitable ground-plane dimensions, air gap and location of the slits, the impedance bandwidth can be enhanced upto 10.15 % as compared to conventional rectangular patch (4.24%) with an axial ratio bandwidth of 4.05%.</span></p><p> </p><p> </p>

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.
