B-SHAPED MICROSTRIP PATCH ANTENNA FOR FREQUENCY RANGE OF 5-6.5 GHZ

Abstract

Slotted B shaped Rectangular microstrip patch antenna has been proposed. With the help of CST software, the design parameters and results for a B-slotted rectangular microstrip patch antenna is explained and the results obtained from the simulations are demonstrated. The proposed antenna has been designed using FR4 as substrate having dielectric constant of 4.4 sandwiched in between the patch and ground plane made up of copper. The power from coaxial connector is fed to the B-shaped antenna via microstrip feed line and impedance of the antenna is matched. It has observed that antenna slotted antenna is resonate at frequency 6.4 GHz. Proposed antenna has return loss -39.7 dB at resonant frequency of 6.4GHz. The gain of the proposed antenna is 10dB. For the proposed antenna the VSWR is 1.03. The microstrip patch design is achieved by using microstrip line feed technique. This patch is studied because they offer high bandwidth and gain. The gain enhancement has been achieved by suitable cutting slots in the rectangular patch using suitable feeding technique. The electromagnetic simulation of the proposed antenna has been carried out using CST software. The analysis of performance will be based on changing the geometry of the patch and the obtained results are gain, VSWR, antenna efficiency and radiation pattern.
