Dual wideband n shaped patch antenna loaded with shorting pin for wireless applications

In this paper, a compact N shaped dual band patch antenna loaded by shorting pin is designed. The lessening in patch size is achieved by perturbing the surface current path on the edge of a circular patch antenna by two triangular slots which make the patch as N shaped. Dual wideband is achieved by combining two triangular slots and shorting pin. Simulated results which are carried out by Finite Element Method (FEM) based simulator HFSS such as antenna impedance bandwidth, input impedance and radiation characteristics have been presented and discussed. The lower impedance bandwidth 1.46 GHz covers from 2.89 GHz to 4.35 GHz and the upper impedance bandwidth 2.17 GHz covers from 7.69 GHz to 9.86 GHz. The overall dimension of the antenna is 13×13×1.575 mm³.
