摘要

本文提出了一种大频率比为8.2的双频滤波天线，在两个工作频带内具有较高的频率选择性，在中间频带具有良好的辐射抑制能力。该天线采用方形贴片，背面为开槽基板集成波导(SIW)腔。利用具有微波/毫米波信号分离功能的馈电网络对辐射元件进行激励。仿真结果表明，该天线可以同时工作在3.4GHz和28GHz频段。在两个阻带处，带外抑制分别大于29 dB和14.2 dB。

A Dual-band Filtering Antenna with a Large Frequency Ratio

This paper presents a dual-band filtering antenna achieving a large frequency ratio of 8.2, which reveals high frequency selectivity within two operation bands and good radiation suppression at the middle band. The antenna is implemented using a square patch backed with a slotted substrate integrated waveguide (SIW) cavity. A feed network possessing the function of microwave (MW)/ millimeter-wave (MMW) signal separation is utilized to excite the radiating element. Simulated results show that the antenna can simultaneously work at 3.4GHz and the 28GHz. Besides, the out-of-band suppression is larger than 29 dB and 14.2 dB at two stop bands.
