The radio frequency (RF) signal passes through the waveguide-to-suspended microstrip probe transition from the standard waveguide WR4 to the suspended microstrip circuit, and the local oscillator (LO) signal passes through from the high-reduced waveguide WR10 to the circuit. The circuit is designed using two MA4E2038 Schotty diodes on the quartz-based substrate with dielectric 3.78, thickness of 0.127mm. When the LO frequency is fixed at 105GHz, the simulated conversion loss is less than 8.2dB from 215GHz to 225GHz.","PeriodicalId":421574,"journal":{"name":"2012 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116980122","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, ultrawide bandwidth is achieved by a rectangular patch antenna over a specifically designed artificial magnetic conductor (AMC). Replacing the traditional ground plane with the proposed AMC succeeds in the significant enhancement of the bandwidth ranging from 0.9 MHz to nearly 24 GHz. Besides the great improvement in the bandwidth, the other performances of the antenna such as the gain and efficiency are improved as well. Details of the proposed antenna design are offered in this letter and experimental results are also presented here.","PeriodicalId":421574,"journal":{"name":"2012 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"15 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120847564","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}
