Effects of Slot Loading on Microstrip Patch Antennas

Sunandan Bhunia

Abstract


This study presents the theoretical and experimental investigation on the effect of rectangular slot on resonance frequency, return loss and band widths of a novel, single layer, single probe-fed rectangular microstrip patch antenna. The novel design is achieved by cutting the rectangular slots at the one radiating edge of the patch antenna. Compared to the conventional rectangular patch antenna, slot loading antennas give the better performance in resonant frequency, return loss in the cost of bandwidths. Resonance frequency reduction has also been achieved up to 36% as well as size reduction of more than 60%.
