摘要

提出了一种新型的基于左/右复合传输线的微波功率分配器。功率分配器由一段CRLH TL和若干微带线组成。本设计基于CRLH TL的零阶谐振，设计了一个2.4 GHz的功率分配器样机。不平等的权力划分很容易实现。它在纵向上非常紧凑。所提出的CRLH功率分配器的总插入损耗小于1.2 dB。输出端口之间具有良好的相位平衡和隔离性。

An Unequal Power Divider Using Composite Right/Left-Handed Transmission Line Couplers

A novel microwave power divider based on composite right/left-handed transmission line (CRLH TL) is presented. The power divider is composed of a segment of CRLH TL and several microstrip lines coupled with it. This design is based on the zeroth order resonance of CRLH TL. A prototype power divider at 2.4 GHz is presented. Unequal power division can be easily achieved. It is very compact along the longitudinal direction. The total insertion loss of the proposed CRLH power divider is less than 1.2 dB. Good phase balance and isolation among output ports are obtained.
