- Abstract
The distribution of current in a patch antenna changes with the variation in the ground dimensions. This changes the radiation properties, impedance and performance parameters of antenna under study. In this paper, a parametric analysis of size of ground in a small rectangular microstrip antenna at frequencies 2.4 GHz, 5 GHz and 10 GHz is performed and its influence on antenna performance is investigated. Also, the equivalent circuit analysis is done to show the effect of inductance, capacitance and resistance values of coaxial probe and patch on the resonant frequency and performance of the antenna. CST Microwave Studio simulator has been used for the design and simulation of the patch antenna. The influence of ground dimensions on different performance parameters of antenna like gain, return loss, frequency shift, radiation pattern, total efficiency and directivity were studied and are presented in the paper.
