Abstract :
A new configuration of extended hemispherical lenses with an air cavity above the feed region has been proposed. This technique enables one to achieve the same beam patterns as synthesized elliptical lenses, but with smaller height (10.1%), dielectric loss (15.7%) and weight (13.6%). Various lens configurations fed by printed patch antennas have been designed and compared in Ka-band.
