摘要
介绍了一种UHF波段宽频带高增益八木天线阵。阵列单元为折合振子八木天线,其匹配采用U型管平衡-不平衡变换器,使用高频软件综合优化,并与专用八木天线设计程序相结合,实现了天线单元10%以上的工作带宽。经过工程设计,用实验的方法解决了多项技术难点,整体指标基本达到预定要求,同时也提出了后续改进的途径和方法。
A UHF-band high-gain wideband Yagi antenna array is introduced.The working bandwidths of over 10% of the antenna elements are realized in combination with the special programming of the Yagi antenna through the integrated optimization of the HF software with the Yagi antenna vibrators as the array elements and the U-shape tube balanced and unbalanced converters as the matching.Several technical difficulties are solved through the engineering design and test,and the predetermined requirements of the overall index are basically achieved.At the same time,the follow-up improved methods are presented.
