Abstract :
In this letter, a novel Psi-shape microstrip patch antenna that provides wide-impedance bandwidth performance in addition to the acceptable radiation patterns is presented. The substrate is a foam material, and for ease of fabrication, the patch is etched on a thin dielectric layer, which is placed over the foam and fed by a coaxial probe. The simulated and measured 2:1 VSWR impedance bandwidths are 55% and 54%, respectively. The measured and simulated radiation patterns are in acceptable agreement as well. The measured front-to-back (F/B) ratio is better than 20 dB throughout the frequency band.
