Abstract :
Three versions of a new quarter-wave Fresnel zone antenna comprising multi-dielectric plate lenses and designed for reception of DBS signals are described, and their main radiation parameters are given. The antennas show aperture radiation efficiency higher than 50% and gain versus frequency bandwidth of more than 20%.
