To enable the quest for high data rates in telecommunications, wide-band radio designs as well as antennas are required. This paper demonstrates a unique bandwidth enhancement technique for L-probe fed patch antenna. This is a novel technique to enhance patch antenna bandwidth with desired radiation properties. One circular shape main patch and two elliptical shape parasitic patches on PCB give wide-band response by exciting multiple resonances. The designed antenna array gives almost 45%, -10 dB impedance matched relative bandwidth. This is a very simple and inexpensive patch antenna solution for the wide-band wireless application. A two-element array of this antenna has been formed, and wide-band radiation properties of the array are reported.
