Abstract :
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 fabrication.
