Abstract
A cost effective implementation of a ‘Smart Antenna’ is limited due to the number and high cost of RF array elements, RF distribution as well as phasing elements. Shaped Dielectric Lenses perform the task of collimation, to obtain multiple beams in a fixed set of directions. Lenses are inherently broadband, lower in cost, easy to fabricate, have lower dimensional tolerances, and act as a radome for the electrically small primary radiators that are embedded inside or placed behind the lens.
