摘要
天线系统一般包括天线及馈电两部分 ,系统的宽频带特性不仅取决于天线性能 ,而且还与馈电系统及两者之间有效耦合、匹配情况有关。其中 ,平衡器是馈电系统的重要组成部分。本文简述了天线馈电中引入平衡器的作用 ,同时针对平衡器设计中通常存在带宽较窄、功率容量低的特点 ,提出一种宽频带平衡器的设计方法 ,并在理论和实际应用中同时加以验证。
Antenna system generally includes an antenna and a feeding system It′s wide band characteristic is decided not only by the antenna′s performance but also by feeding system, available coupling and matching between antenna and the feeding system The balun is an important part in feeding system In this paper, we propose the function of balun in antenna feeding and give a design method of wideband balun aiming at the problem of narrow bandwidth and low power capacity in balun designing This method has been proved available in theory and practical application
