Abstract

In this paper a slot has been loaded in square patch antenna which was resonating originally at three different frequency bands viz. 7GHz, 10GHz and 13GHz. The loading of the slot results in the suppression of higher frequency bands and reduction in resonant frequency of original square patch antenna. Reduction in the resonant frequency results in the reduction in the size of patch antenna. The slot loaded patch resonates at 5GHz and the simulation results indicate the return loss at 5GHz is-33.75dBi, VSWR is 1 and gain is 6.2dBi. The paper compares the parameters of original and slotted patch antenna. The IE3D electromagnetic simulation and optimization engine based on MoM has been used for the purpose.
