Abstract:

 

Rotman lenses are constrained lenses that are used as   beam-forming networks to feed array antennas. Their design is based on three   focal points, producing three beams with perfect phase fronts. This paper   introduces an alternative constrained lens, which has phase equality at five   radiating array elements for each beam position. In addition, the center   point of the feed curve produces a perfect beam at broadside. The   performance of this lens is analyzed and compared to the conventional Rotman   lens. The analysis demonstrates that the new lens has better phase   performance for wide angle designs. Our study shows that the phase errors of   the proposed lens can be as low as half of those produced when using the   conventional Rotman lens.
