Square Shaped Ultra Wide Band Antenna for Wireless Application

A new planer Ultra Wide Band (UWB) antenna fed by a 50-Ohm microstrip line for wireless application is presented. Ground plane of the antenna is designed such that it increases the directionality of the radiator so that antenna can also be successfully used for radar application. From the simulated and measured results it is stated that the designed antenna exhibits low return loss, high directivity in the band of interest between 4.51-7.21 GHz and bandwidth achieved is 47%. Since the designed antenna comes in C-band so it also can be used in WLAN application.
