Jamali, BehnamCook, Tony2014-05-142014-05-142013Proceedings of the International Conference on Radar, RADAR 2013, 9-12 September 2013, Adelaide, Australia: pp.179-1839781467351782http://hdl.handle.net/2440/82870This paper presents a comparative study of patch antenna feed structures. That includes microstrip line feed, inset feed, coaxial feed, aperture coupled feed and proximity coupled feed. Matching between the patch antenna and the feed network heavily depends on the feed technique used. In this work we review various feeding techniques to provide an understanding of the important design parameters and their effects on the bandwidth, gain and the other important antenna characteristics. Various simulation tools, commercial and internally developed are used during this work.en© 2013 Commonwealth of AustraliaConference paper002013450410.1109/RADAR.2013.6651981
