中文摘要：
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（CSS—RR），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1．13dB。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。
英文摘要：
A novel complementary split single ring resonator（CSSRR） is designed using the unique phase charac- teristic of the Composite Right/Left-Handed（CRLH） transmission line, then a 22.5° phase shifter is designed, fabricated and measured. The measurement results show that the absolute error in operating band is within ± 0.56°, and the insertion loss is below 1.13 dB. The measurement results have a good agreement with the simulations, which verifies the correction of the design.
