The UWB systems need the antenna with the same radiation pattern and the stable gain in the whole frequency range. In this communication a compact ultra-wideband differential wide-slot antenna (DWSA) with the improved radiation pattern and gain is proposed. By truncating the corners of the ground plane, the current distribution in it becomes more ordered and the radiation performance of the proposed DWSA in the upper frequency band is effectively improved. Further, one strip line is loaded in the ground plane along the symmetric line in order to strengthen the virtual ground and reduce the influence of asymmetry factor brought by the processing error. The measured results show, the fabricated DWSA presents a -10 dB impedance bandwidth of 133.1% (from 2.49 to 12.41 GHz). Moreover, in the whole band, the antenna basically keeps the same radiation pattern and the gain is over 1.3 dBi. The measured results are in agreement with the simulated results.
