摘要

本文提出了一种二维扫描欺骗表面等离子激元（SSPP）双工漏波天线（LWA），可实现二维实时传感。该天线工作在双频段，只有一个馈电端口，消除了设计由复杂波束形成网络（bfn）连接的LWA阵列的需要，而传统的方法是实现二维扫描。采用引入不对称的SSPP传输线来提高扫描速率，抑制LWA的开阻带（OSB）。被测天线在6.2 ~ 7.4 GHz的方位面上实现了93°的连续扫描，在8.2 ~ 9.4 GHz的仰角面上实现了102°的连续扫描。在此基础上，针对目标跟踪场景，建立了一种基于双工LWA的分频微波传感系统。仿真和测量结果验证了天线的有效性。

A 2-D Scanning Spoof Surface Plasmon Polariton Diplexing Leaky-Wave Antenna for Sensing Applications

In this article, a 2-D scanning spoof surface plasmon polariton (SSPP) diplexing leaky-wave antenna (LWA) capable of 2-D real-time sensing is presented. The antenna operates in dual bands with one single feeding port, eliminating the need for designing an LWA array connected by complex beam-forming networks (BFNs) as in the traditional approach to achieve 2-D scanning. SSPP transmission lines with introduced asymmetry are employed to enhance the scanning rate and suppress the open stopband (OSB) of the LWA. The measured antenna achieves continuous scanning over 93° in the azimuth plane from 6.2 to 7.4 GHz and 102° in the elevation plane from 8.2 to 9.4 GHz. Furthermore, a frequency-diverse microwave sensing system based on the diplexing LWA is established for target-tracking scenarios. Simulation and measurement results are provided to validate the antenna’s efficacy.
