A Wang-shaped suspended patch antenna has been designed for wireless communication systems covering the 1.66GHz-2.43GHz frequency range. This frequency range covers the major standards in mobile communications such as PCS1900 (1.88GHz-1.9GHz), UMTS (1.92GHz-2.17GHz), and WiBro (2.3GHz-2.39GHz). The Wang-shaped patch is proposed in this paper for bandwidth broadening whilst maintaining symmetrical radiation patterns in both the E and if-plane. By using a simple low-cost feed network, Wang-shaped patch fed by dual L-probe yields a return loss bandwidth (10-dB) of 37.7% and max gain of 6.5 dBi at the mid-band frequencies. The radiation patterns and the cross-polarization of the antenna are also examined.
