An improved unit cell of composite right/left handed transmission line is proposed. The electrical equivalent circuit of the unit is discussed. In addition, the cell has a better selectivity and out-of-band rejection, which is very distinguished from the conventional CRLH TL cell. And the parameters of the cell are discussed specifically. After properly designed the parameters, a compact narrow bandpass filter is generated. It has a transmission zero at the lower stop band, and is found that the filter enables the remarkable size reduction from the conventional CRLH TL filters.","PeriodicalId":150727,"journal":{"name":"The 2012 International Workshop on Microwave and Millimeter Wave Circuits and System Technology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123897881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present the design and testing of a compact wideband 90° phase shifter with small phase error using CRLH transmission line. The wideband phase shifter is obtained by subtracting of two phase shift parts. The properties of the CRLH transmission line are analyzed and the empirical formula is given to determine the phase shift of the transmission line against with the length of the interdigital capacitance. According to the formula, a 90° phase shifter with a phase error of ±3° has been achieved. The implemented phase shifter works from 4.225GHz to 5.709GHz with a small size of less than 35mm×50mm in total.

The optimized structure is simulated by the electromagnetic simulation software CST Microwave Studio, and a satisfied chirped group-delay is achieved ranging from 0.2 GHz to 3.85 GHz.
