Abstract

A novel structure is proposed for the dual-band self-diplexing integration of microstrip line and leaky wave antenna (LWA). Through introducing a mode selective transmission line (MSTL) to the antenna, the autonomous transition between transmission modes at varying operating frequencies is thus achieved. At the high-frequency band, such proposed antenna in the quasi-TE₁₀ mode, the periodic slots, and patches are used as LWA. Meanwhile, at the low-frequency band, the baseband signal with quasi-TEM mode can be transmitted effectively. These experimental results demonstrate that this design strategy benefits the realization of transmission with an insertion loss of less than 3 dB below 5.5 GHz. Furthermore, this antenna enables continuous beam scanning of −1 space harmonics from 10.5 to 15.5 GHz, with a beam direction sweeping from −75° to + 54°. This study innovatively employs MSTL structure to solve the problem of radio frequency (RF) and baseband links operating independently in traditional communication systems. It provides a promising solution for multi-functional integrated applications in future wireless communications.

具有自双工特性的复合微带线和漏波天线结构

针对微带线和漏波天线（LWA）的双频自双工集成提出了一种新结构。通过在天线中引入模式选择传输线（MSTL），实现了不同工作频率下传输模式之间的自主转换。在高频段，这种拟议的准 TE10 模式天线、周期性槽和贴片被用作 LWA。同时，在低频段，准 TEM 模式的基带信号也能有效传输。这些实验结果表明，这种设计策略有利于在 5.5 GHz 以下实现插入损耗小于 3 dB 的传输。此外，这种天线还能对 10.5 至 15.5 GHz 的 -1 空间谐波进行连续波束扫描，波束方向从 -75° 到 + 54°。这项研究创新性地采用了 MSTL 结构，解决了传统通信系统中射频（RF）和基带链路独立运行的问题。它为未来无线通信中的多功能集成应用提供了一种前景广阔的解决方案。
