摘要：A stacked arrangement of square patch antenna is proposed and analyzed in this paper. An antenna is designed by using glass epoxy-FR4 substrate. In the proposed stacked arrangement there are two patches: driven (lower) patch & parasitic (upper) patch, both patches having the same dimension. There is an air gap of 1 mm between these two patches. The driven patch is fed through probe feed with sub miniature version A (SMA) connector and the upper structure is parasitically coupled to the driven patch. Simulation results which are presented in this paper are return loss, input impedance, voltage standing wave ratio (VSWR) and 2-D radiation pattern. Simulation process is done by using IE3D simulator. Simulation results of stacked arrangement are compared with single square patch antenna of same size. This proposed antenna operates at two resonant frequencies and also has a relatively broad impedance bandwidth (33.74%).
