摘要

本文介绍了一种具有滤波特性的郭线漏波天线。该设计的新颖之处在于将滤波功能集成到平面的瓜波线LWA中。这种集成导致天线的带通行为。漏波辐射是通过在单导体传输线上加入修正的对称周期性扰动而产生的。这种改进的扰动进一步降低了导体损耗，从而使天线的最大增益达到11.5 dBi。采用环形谐振器在平面传输线上引入滤波功能，提供5.5 GHz和11 GHz的滤波零值，工作带宽为35% (7 GHz - 10 GHz)， 38°反向波束扫描。该天线具有良好的辐射性能和滤波性能。

Realization of filtering leaky-wave antenna in Goubau-line

A Goubau-line leaky-wave antenna (LWA) having filtering property is introduced in this work. The novelty of the design is integration of filtering function in a planar Goubau-line LWA. This integration leads to a bandpass behavior of the antenna. The leaky-wave radiation is generated by incorporating modified symmetrical periodic perturbation along the single conductor transmission line. This modified perturbation reduces the conductor loss further, resulting in a maximum antenna gain of 11.5 dBi. Filtering function is introduced in this planar transmission line by a ring resonator providing the filtering nulls at 5.5 GHz and 11 GHz and the operating bandwidth of 35 % (7 GHz–10 GHz) with 38° backward beam scanning. The proposed antenna demonstrates good radiation performance with filtering properties.
