Experiments were conducted using a fabricated prototype placed inside a cylindrical cavity. The results were compared and verified with simulated data obtained using an electromagnetic simulator. About 9.6 to 10.5 dBi peak gain was obtained from measured and simulated data 2008-11-29T00:00:00Z http://dyuthi.cusat.ac.in:80/xmlui/handle/purl/501 Apsym Tenth National Symposium On Antennas And Propagation K G Nair; Balakrishnan,K G; P R S Pillai; Vasudevan,K; Mathew,K T; Mohanan,P; Aanandan,C K 2006-01-01T00:00:00Z http://dyuthi.cusat.ac.in:80/xmlui/handle/purl/500 Apsym Ninth National Symposium On Antennas And Propagation K G Nair; Balakrishnan,K G; P R S Pillai; Vasudevan,K; Mathew,K T; Mohanan,P; Aanandan,C K 2004-01-01T00:00:00Z http://dyuthi.cusat.ac.in:80/xmlui/handle/purl/499 Apsym Eighth National Symposium On Antennas And Propagation K G Nair; Balakrishnan,K G; P R S, Pillai; Vasudevan,K; Mathew,K T; Mohanan,P; Aanandan,C K 2002-01-01T00:00:00Z
