基于并联枝节蜿蜒线的小型化微波六端口结设计

Design of miniaturized microwave six-port junction using shunt-stub-based meander line

首次提出了一种并联枝节蜿蜒线。利用周期性结构传输线理论,首先对并联枝节蜿蜒线进行了结构与理论分析,提出了具体设计方法,并利用该方法成功设计实现了一个中心频率为2.4 GHz的小型化微波六端口结。该六端口结的电路尺寸仅为传统结构的25.3%,并且不以损失电性能为代价,具有与传统结构相近的频率响应特性。

A miniaturized microwave six-port junction using a newly presented shunt-stub-based meander line was proposed. The structure and theory of the proposed meander line were analyzed, while an effective design procedure was presented. A prototype six-port junction of 2.4 GHz center frequency was designed, fabricated and measured. The circuit size of the proposed six-port junction is just 25.3% of that of the conventional one. Furthermore, the proposed six-port junction doesn’t sacrifice any electrical characteristic and has the similar frequency responses with those of the conventional one.
