Abstract :
In this paper a multilayer multi-resonator probe-fed microstrip antenna is numerically investigated using Method of Moments (MoM). The antenna structure includes a feed patch and two parasitic patches located on the bottom layer while another parasitic patch is placed on the top layer and the two layers are separated by an air gap. The effect of feed-point location and distance between parasitic patches with feed patch on the radiation performance of the antenna are investigated. The results show that impedance bandwidth of 7.6 GHz (53.9%) for VSWR<2 and gain of 7.53 dB is obtained.
