摘要：

In this letter, a new wide stopband and high gain Quasi-Yagi filtering antenna is proposed. At the beginning of feeder line in the improved Balun filtering antenna, it is integrated with the stripline low-pass filter that contributes to wide out-of-band suppression. The proposed filtering antenna works from 2.25 GHz to 2.55 GHz, with a maximum gain of 8dBi at 2.5 GHz. Moreover, it possesses a faster roll-off rate from 2.55 GHz(8 dB) to 2.8 GHz (-20 dB) and a better rejection up to 12 GHz(5 times of central frequency) outside the working band.
