摘要

摘要本文提出了一种新型的小型化（1.2λ0×0.5λ0×0.026λ0）频率可重构行波天线（TWA），工作在8-12 GHz频带。该天线使用以新颖配置布置的PIN二极管来产生频率可重新配置性，并基于不同的开关配置在8.5、9、9.35、9.9、10.45和11GHz的单个频带上工作，平均带宽为1GHz。所提出的天线在不同站的工作频率下表现出>80%的效率，同时保持8.5dBi的稳定平均增益。该天线的紧凑性和高增益使其适用于现代卫星通信设备和雷达系统中的多种应用。利用CST微波工作室设计并测试了所提出的天线的一致性。在消声室中测量的制造原型进一步验证了所提出的设计，与模拟结果吻合良好。

X-band Miniaturized frequency reconfigurable travelling wave antenna

ABSTRACT The paper presents a novel miniaturized (1.2 λ0 × 0.5 λ0 × 0.026 λ0 ) frequency reconfigurable travelling wave antenna (TWA) operating at 8–12 GHz band. The antenna uses PIN diodes arranged in a novel configuration to produce frequency reconfigurability and operates at single frequency bands of 8.5, 9, 9.35, 9.9, 10.45 and 11 GHz with an average bandwidth of 1 GHz based on different switch configurations. The proposed antenna demonstrates an efficiency>80% for the operating frequency in different stations while maintaining a stable average gain of 8.5 dBi. The antenna’s compact nature and high gain make it suitable for several applications within modern satellite communication devices and radar systems. The proposed antenna is designed and tested for its conformality using CST Microwave-Studio. The proposed design is further verified with a fabricated prototype measured in an anechoic chamber, agreeing well with the simulated results.
