The effect of loading patches only on corrugated side, uncorrugated side and both the sides of the asymmetrical corrugated SSPP line is studied. The advantage of using asymmetrical corrugated SSPP line is the reduction in the width of the line. Antenna with loaded patches on corrugated side, uncorrugated side and both side, operates in the frequency range 8.5-11 GHz, 8.5-10 GHz and 8-11 GHz with maximum gain of13.2 dBi, 12.5dBi and 15.7 dBi and scan range of 63°, 36° and 77° respectively. This study tells that the loading of patches on corrugated side provides the better gain and scan range compared to other two cases.","PeriodicalId":137840,"journal":{"name":"2022 International Symposium on Antennas and Propagation (ISAP)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132328506","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}

The most well-known multi-beam lens is the Abbe’s sine condition lens. On multibeam applications, finding optimum feed position is required. Focal region ray tracing is a very useful technique to find possible best feed position. In this paper, focal region ray tracing on Abbe’s sine condition lens is presented. Lens shape is determined by the lens shaping method. Then, the ray tracing is conducted. It shows good agreement with the theoretical locus of Abbe’s sine condition lens.
