In this paper, a compact planar antenna with a bandwidth enhancing technique named folded patch feed is presented. The design adopts contemporary techniques; coaxial probe feeding, slotted patch structure and shorting wall. The composite effect of integrating these techniques and by introducing the proposed patch, offer a low profile, broadband and low cross polarization level. The results for the VSWR and radiation patterns are presented. The antenna operating the band of 2.39-2.49 GHz (impedance bandwidth of 3.3%) and upper band of 5.03-6.45 GHz which shows an impedance bandwidth of 24.8%. Good radiation characteristics, including low cross-polarization level in E-plane for both bands have been obtained.
