For the ON-state, the four modes are excited by the planar microstrip lines to construct the dual-band filtering response, leading to miniaturized size. Thanks to the quad-mode orthogonality, the two passband could be designed independently. Besides, the diodes are turned off in this case, avoiding the additional loss introduced into passbands. For the OFF-state, all the four modes are eliminated via the symmetrical feeding structure, resulting in high isolation. For verification, a prototype is fabricated and tested. Low loss dual-band filtering response with high selectivity and high isolation are both exhibited with miniaturized size, supporting the proposed method.","PeriodicalId":143802,"journal":{"name":"2021 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133159148","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}

They consist of 19 and 15 elements respectively. An obvious size reduction rate of 44% in the axial direction is obtained through the RPO method at 2–20 GHz.
