摘要

可以在特定频带上工作的频率无关波束扫描漏波天线(LWAs)是未来无线系统非常需要的。本文开发了一种复合右/左(CRLH) LWA，以促进这些功能。它利用两组变容二极管来实现与频率无关的波束扫描能力。优化的可重构CRLH LWA及其简单的直流偏置网络实现了在4.75和5.25 GHz之间的每个频率点扫描超过100°的模拟频率无关波束。制作了天线样机并进行了测试。5.0 GHz下的实测结果证实了其仿真性能特征。

Wide-Angle Wideband Frequency-Independent Beam-Scanning Leaky Wave Antenna

Frequency-independent beam scanning leaky-wave antennas (LWAs) that can operate over a specific frequency band are highly desirable for future wireless systems. A composite right/left-handed (CRLH) LWA is developed in this paper that facilitates these functionalities. It utilizes two groups of varactor diodes to realize the frequency-independent beam scanning capability. The optimized reconfigurable CRLH LWA and its simple DC biasing network achieves a simulated frequency-independent beam that scans over 100° at each frequency point between 4.75 and 5.25 GHz. An antenna prototype was fabricated and tested. The measured results at 5.0 GHz confirm its simulated performance characteristics.
