摘要

提出了一种工作在0.9÷2.5 GHz频率范围内的紧凑型宽带微带双工器。该组件是多功能天线馈电网络的关键部分，在与地面和卫星无线电业务有关的五个频带上工作。将数字间电容与阶跃阻抗技术相结合，在紧凑性和性能方面取得了很好的效果。一种非常规的过滤器布置使得尺寸进一步减小。

Planar Microstrip Diplexer for a Multifunctional Antenna

A compact wide-band microstrip diplexer working in the 0.9÷2.5 GHz frequency range is presented. This component is a key part of the feeding network of a multifunctional antenna, working at five frequency bands associated to terrestrial and satellite radio services. By using interdigital capacitors in conjunction with the stepped impedance technique, very good results in terms of compactness and performances have been obtained. An unconventional arrangement of the filters has led to a further reduction of the dimensions.
