This configuration has attrated attention for two applications: The dielectric image line above the slot can be designed to act as a shielding, thus reducing radiation losses if a diode is mounted above the slot e.g. in a detector- or mixer-circuit. On the other hand, similar to slots in metal waveguides, slots in the ground plane of dielectric image lines can be designed for antenna applications and even for nonradiating filter-structures.","PeriodicalId":120372,"journal":{"name":"1981 IEEE MTT-S International Microwave Symposium Digest","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123795341","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}

Field expressions are written in each region of the junction in form of infinite summation of the corresponding region modes. Matching of the fields at the common boundaries, taking fringing fields in microstrip structures into account, leads to a set of infinite non-homogeneous equations in these mode-amplitudes. A wideband microstrip circulator, designed using the point-matching technique, is observed. The 20-dB isolation bandwidth is about 62% without using any external tuning elements.","PeriodicalId":120372,"journal":{"name":"1981 IEEE MTT-S International Microwave Symposium Digest","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114181683","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}

An element of resonator filter is composed of a square dielectric post and a round inner conductor. Each element of resonator is allocated in a housing similar to conventional combline filter, however, the length of a resonator is basically a quarter-wavelength long. The higher unloaded Q and a larger inter-resonator coupling were brought through two factors: open-boundary condition on the periphery along the dielectric post and the air spacing between resonators. Five-stages Tschebyshev response band-pass filters were developed at 800 MHz band to have 20~30 MHz pass-band and 0.8~1.0 dB insertion loss at the temperature range: -35~+80/spl deg/ C, The volume and the weight of the filters are about 25 cm/sup 3/ and 60 gramms.","PeriodicalId":120372,"journal":{"name":"1981 IEEE MTT-S International Microwave Symposium Digest","volume":"180 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128351529","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}
