This receiver operates at L1(1575.42 MHz) frequency band for GPS signal, L5(1176.45MHz) and S-Band (2492.028MHz) for IRNSS signals. The NavIC receiver is expected to receive RF signal with omni-directional coverage. To cater this two antenna element are mounted on outer surface of launch vehicle in diametrically opposite direction. RF Signals from two antenna elements are combined through a power combiner and fed to NavIC receiver. An equal-split Wilkinson power combiner is designed and fabricated. Designed power combiner meets the specifications at all three frequencies. Also the measured insertion losses are better than −3.3dB between the ports. Good amplitude & phase balance is obtained from the circuit. Realization aspects, simulated and measured results are discussed in this paper.","PeriodicalId":201547,"journal":{"name":"2021 IEEE Indian Conference on Antennas and Propagation (InCAP)","volume":"49 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114124402","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 ratio of focal length to the diameter of the proposed lens is 0.2. Another conformal metasurface is designed using the unit cells of the planar lens but arranged in a different sequence which causes beam steering of the microstrip patch antenna at two specific angles -20° and 50°.
