提出了一种利用奇模欺骗表面等离子体激元(SSPP)进行宽边辐射的基片集成波导天线。在SiW-SSPP混合结构的上表面刻蚀了双光栅，激发了SSPP奇模。所提出的SIW天线具有开路终端，可以实现宽边辐射。制作了一台基于SIW的奇模天线样机。实验结果与模拟结果吻合较好。当|S11| <； ； −为10 分贝时，天线阻抗带宽约为5.5%(12.4~13.1 GHz)。在12.3~13.3 GHz的工作频段内也实现了稳定的宽边辐射，在5.6 6~6.34 分贝的频段内获得了稳定的增益。该宽边辐射天线结构紧凑，具有良好的辐射性能，适用于无线通信系统。
In this article, a substrate integrated waveguide (SIW) antenna utilizing odd‐mode spoof surface plasmon polariton (SSPP) for broadside radiation is proposed. Double gratings are etched on the top surface of SIW and the SSPP odd‐mode is excited on this hybrid SIW‐SSPP structure. The proposed SIW antenna has open‐circuit termination and can realize broadside radiation. A prototype of the SIW‐based odd‐mode antenna is fabricated. Reasonable accordance is achieved between measured results and simulated results. The antenna impedance bandwidth is about 5.5% (12.4~13.1 GHz) with |S11| < −10 dB. Stable broadside radiation is also realized within the operating band of 12.3~13.3 GHz and the measured gain varies from 5.66 to 6.34 dB in the frequency band. The proposed broadside radiation antenna is suitable for wireless communication systems due to its compact structure and good radiation performances.
