Abstract :
In the paper one aperiodic constrained active lens generating a multiple spot contiguous beams coverage is proposed. The antenna is optimized in terms of number of radiators, dimensions, weight, and power amplifiers efficiency. The antenna represents an interesting architecture based on a single aperture able to replace conventional antennas based on multi reflector dishes onboard geo or non-geo stationary satellites. Experimental results recently achieved are presented.
