摘要

提出了一种基于衬底集成波导的低轮廓宽阻带滤波天线。首先，提出了一种采用两个有限传输零点(FTZs)的死胡同拓扑方案的五极带通滤波器。SIW滤波器由三个使用TE101模式的单模腔和一个使用TE201和TE103模式的双模腔组成，通过抑制TE102、TE202和TE104模式实现了宽阻带。然后设计了一个腔背槽天线，使其带宽比滤波器的带宽窄，从而使其表现为一阶谐振器。该天线具有良好的阻带性能，中心频率为10 GHz，分数带宽为4.03%，增益平坦，增益为7.8 dB。

Low-Profile Filtering Antenna With Wide Stopband Using Dual-Mode Rectangular SIW Cavities

A low-profile filtering antenna with a wide stopband based on substrate integrated waveguide (SIW) is presented in this article. First, a five-pole bandpass filter using a cul-de-sac topology scheme with two finite-transmission zeros (FTZs) is proposed. The SIW filter which consists of three single-mode cavities using TE101 mode and a dual-mode cavity using TE201 and TE103 mode achieves a wide stopband due to the suppression of TE102, TE202, and TE104 mode. Then a cavity-backed slot antenna is designed so that its bandwidth is narrower than that of the filter, thus making it behave as a last-order resonator. With a center frequency of 10 GHz and a fractional bandwidth of 4.03%, the antenna has good stopband performance and achieves a gain of 7.8 dB in terms of a flat gain profile.
