The objective of this paper is to investigate the feasibility of shaping lens radiation patterns without shaping the lens profile as traditionally done. The proposed solution is based on focal array fed lens antennas that consist of standard extended hemispherical integrated lenses illuminated by focal phased sub-arrays. To demonstrate the feasibility of this concept, beam shaping techniques at the...
We have shown that a single antenna array excited by two different feed networks and illuminating a shaped substrate lens enables one to generate two radio coverage by properly shaping the lens profile and optimizing the array parameters (number of elements, amplitude of excitation, inter-element spacing). This concept has been successfully applied to SRR / LRR sensors. Antenna prototypes are under...
