摘要:

利用复合左右手传输线独特的相位特性，设计了一个新型零相移的逆开口谐振单环（CSSRR），在此基础上，设计了一个225°移相器，并对其进行了加工和测试。实测结果表明，该移相器工作频带内相移误差在±056°以内，插入损耗优于113 dB 。实测结果与仿真电路吻合较好，证明了所提出方法的正确性和有效性。

Abstract:

A novel complementary split single ring resonator(CSSRR) is designed using th e unique phase characteristic of the Composite Right/LeftHanded(CRLH) transmis sion l i ne, then a 225° phase shifter is designed, fabricated and measured.The measur ement results show that the absolute error in oper ating band is within ±0.56°, and the insertion loss is below 1.13 dB. The meas urement results have a good agreement with the simulations, which verifies the c orr ection of the design.
