The cross-shaped line and two series transmission lines are employed to allow matching between source impedance and a given load impedances at three different operating frequencies. The required circuit parameters of the proposed structure are computed using the derived analytical equations. A simple synthesis approach is provided to develop triple-band impedance transformer. To validate the analytical derivation, two prototypes of triple-band impedance transformer are designed, simulated and tested for smaller (10 Ω) as well as larger (400 Ω) load impedances. The simulated and measured return loss are greater than 20 dB at three operating frequencies. The prototypes exhibit good performance between measured and simulated results.","PeriodicalId":162908,"journal":{"name":"2019 IEEE Asia-Pacific Microwave Conference (APMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130104073","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}

To cover different wireless frequency bands, different passive matching components for different frequency bands were used without changing the layout. Quarter wave line lengths were adjusted to cover various bands by providing options with a series of capacitors on quarter wave lines.
