A new via-less end-wall MS-RWG interconnection with multiple open stubs is explored to eliminate the use of via holes in higher frequency band, and thus breaks through the limitation of low-loss and wideband applications. And moreover, the bandwidth is further expanded by the open stubs with different lengths. A 340 GHz interconnection is designed and fabricated as an example for the MMIC-to-RWG application. The measured insertion loss and return loss are respectively better than 0.9 dB and 12 dB from 314GHz to 369 GHz after the microstrip transmission lines in the test fixture are calibrated. The proposed integration solution brings benefits of wideband performance, easy manufacture and low cost, which has potential applications in MMW/THz microsystems.","PeriodicalId":211726,"journal":{"name":"2022 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129916165","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, the influence of feed antenna tilt on antenna gain is investigated theoretically, and a forward free-form surface optimization method to expand FoV is proposed, thereby designing a wide-scan MMW focal plane array with a free-form surface reflector, which provides a high antenna gain of 46.5dB. The staggered placement of feed antennas achieves a 3dB effective isotropic radiated power (EIRP) within a relatively large field of view, up to +/-18.7°. The FPA uses a paraboloid-based Zernike freeform reflector that optimizes the illumination of the far field region according to the feed pattern. In this way, we could improve the FoV and increase feed elements of the system without worrying about coupling efficiency between the focus field and single mode feed antenna.","PeriodicalId":211726,"journal":{"name":"2022 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114218609","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}
