Abstract
An improved design of the U-shaped stub rectangular slot antenna with a tuning pad for enhancing the impedance bandwidth is proposed. By properly tuning the physical size of the copper pad, a wide impedance bandwidth of the antenna can be achieved for UWB applications. For 10 dB return loss, a impedance bandwidth of the antenna is covered from 2.3 to 12 GHz (135.7%). A gain variation from 2 to 6.82 dBi is obtained.
