QFH provides a circularly polarized cardioid-shaped radiation pattern with a high front-to-back ratio, better circular symmetry in the pattern and very good cross-polarization discrimination over wide coverage. Realization aspects and the measured results of the QFH are discussed here. This antenna is proposed to be used for transmission of satellite telemetry data with Omnidirectional coverage in C-band for India's all upcoming GEO-Stationary and navigational satellites.","PeriodicalId":183215,"journal":{"name":"2011 IEEE Applied Electromagnetics Conference (AEMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130684117","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}

A spiral-shaped DGS-integrated microstrip line enhances the port isolation of the antenna, while feeding the 2.45 GHz port, port-1 to the antenna and filtering out 3.0 GHz receiving signal from port-2. Similarly a rectangular shaped DGS-integrated microstrip line enhances the port isolation of the antenna, while feeding the 3.0 GHz port, port-2 and filtering out the 2.45 GHz signal from port-1. The microstrip line at two different ports integrated with DGS restricts the highorder harmonics signals coming from transmitter or receiver. The patch is excited through microstrip feed line of 75Ω line impedance. DGS-integrated microstrip line offers image impedance of 150Ω and it is controlled by DGS geometry. An experiment of investigating isolation between the ports has been performed by employing with and without DGS. Measurements show an improvement of more than 25dB in the port isolation when DGS integrated microstrip antenna.","PeriodicalId":183215,"journal":{"name":"2011 IEEE Applied Electromagnetics Conference (AEMC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114838484","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}

Dual CP configuration is implemented to enable frequency reuse using polarization diversity. This is realized using a high performance dual CP radiating element.
