Abstract:
This paper addresses the design of a rectangular microstrip patch antenna for wireless communication applications at 3.5 GHz resonant frequency. HFSS V13 software was utilized to develop and simulate the antenna. The FR-4 (flame retardant) substrate material, which has a dielectric constant of 4.4 and a thickness of 1.6 mm, was used to design the antenna. The microstrip antenna has a ground dimension of 53.4182mm*34.822mm and a 50Ω impedance. The drawbacks with this microstrip antenna are high VSWR (voltage standing wave ratio) and the return loss is greater than -10db.There are many ways to get over these drawbacks, but one of them is to alter the size of the antenna—specifically, to change the ground plane's size by 37mm*34. 822mm.This paper compares various antenna parameters, including return loss, VSWR, gain, and directivity by switching the ground plane to partial ground plane.
