  1. The antenna is obtained by extending the longitudinal strip of the fin - line, and etched on a metallized dielectric substrate. it is operating at ka band ( center frequency : 34ghz ), which has a good agreement between simulated and measured results. its e - and h - plane 3db main lobe beamwidth are 79. 25 and 80. 03 degrees respectively with sidelobes less than - 10db
