摘要
基于混合左右手传输线(CRLH-TL)理论,结合LC网络单元结构,使用贴片电容和终端短路微带线,设计并制作了CRLH-TL.此CRLH-TL结构小巧,易于实现,有较好的性能.实验测量结果表明:此CRLH-TL的带宽为1 GHz~5 GHz;中心频率为2.97 GHz,此时传输线的相移为零;插入损耗低于1.3 dB,回波损耗大于10 dB.
Based on the theory of composite right/left-handed transmission line (CRLH-TL) and the LC circuit network, a CRLH-TL using surface mounted capacitors and short-ended microstrip lines is presented. The CRLH-TL is compact and easy to fabricate, and its bandwidth is from 1 GHz to 5 GHz while the center frequency is a: 2.97 GHz, at which there is no phase shifting. The insertion loss is less than 1.3 dB, and the return loss is greater than 10 dB. Measurements agree well with simulation results.
