中文摘要：
提出了一种基于Minkowski互补开口环谐振器（M—CSRRs）的微带复合左右手传输线（CRLHTL）。采用电磁仿真、等效电路模型计算、实验测量相结合的方式研究了CRLHTL的传输特性。在此基础上将CRLHTL应用于宽带微带正交功分器设计和加工制作。仿真与测试结果表明：在2．7—6．6GHz的频带内，回波损耗大于10dB，隔离度优于15dB，相位不平衡和幅度不平衡分别小于90°±7°和0．8dB，相对带宽达到了83．9％。测试结果验证了该CRLHTL设计的有效性。
英文摘要：
This paper presents a new type of microstrip composite right/left handed transmission line （CRLH TL） constructed by Minkowski loop shaped complementary split ring resonators （ M - CSRRs） and interdigital capacitor in the upper metal level. Transmission behavior of novel CRLH TL is researched by EM simulation as well as electrical simulation and validated by experimental measurement. By using the CRLH TL effect, a broadband quadrature power splitter （QPS） is designed and fabricated. The simulation and tested results show that within the frequency band range of 2.7 - 6.6 GHz, all return losses are greater than 10dB while the isolation is better than 15dB, phase non- equilibrium and transmission magnitude difference between two outputs are less than 90°±7° and 0.8 dB respectively, thus the relative bandwidth reaches 83.9%.
