摘要

本文提出了一种利用衬底集成波导(SIW)技术滤波具有可调谐辐射零点的天线的特殊设计方法。采用插入耦合的方法，用t形馈线激励SIW腔体。空腔后置槽滤波天线的辐射装置为位于空腔顶部金属平面上的u形槽。采用Tshape馈线和SIW腔谐振器，获得了满意的天线滤波性能。与其他SIW滤波天线相比，该天线具有良好的滤波性能。利用商用软件HFSS对天线进行了验证。结果表明，该系统的带宽为9.58 ~ 9.64GHz，宽带峰值增益可达6.56 dBi。并绘制了该天线的实现增益曲线，显示出良好的滤波响应。

SIW Cavity-Backed Slot Filtering Antenna with Tunable Radiation Nulls

In this letter, a particular design method of filtering antenna owning tunable radiation nulls using substrate integrated waveguide (SIW) technique is proposed. The SIW cavity is excited using a T-shape feedline by an insert coupling method. The radiating device of cavity-backed slot filtering antenna is a U-shape slot located on the top metallic plane of cavity. The satisfying filtering performance of antenna is obtained by Tshape feedline and SIW cavity resonator. As compared to the other SIW filtering antennas, this antenna obtains a favourable filtering performance, simply. Commercial software HFSS is used to verify the proposed antenna. The results exhibit that bandwidth is 9.58GHz to 9.64GHz and broadside peak gain can reach 6.56 dBi. And realized gain curves of proposed antenna are plotted, showing a good filtering response.
