To utilize the TV white space 470MHz to 806MHz, several wideband antennas are designed in ultra-high frequency (UHF) band. This paper presents the monopole antenna with resonant structures arranged in rectangular loop shape. The overall dimension of the antenna is 160mm x 100mm x 1.6mm. The performance of the antenna in the operating frequency band 596MHz to 733MHz is evaluated using HFSS software. The overall peak gain of the antenna is 1.653dB. In both elevation and azimuth plane, radiation pattern is omnidirectional and the radiation efficiency is 81.79%
