Abstract
A dual-antenna system for receiving signals transmitted via satellite and by terrestrial stations within a single broadcasting service. The dual-antenna system comprises a multi-layer printed circuit substrate as a mounting plate and a satellite antenna including a patch antenna array which has four microstrip patch antenna radiating elements provided on a top surface of the first backgrounded dielectric substrate mounted on the top face of a multi-layer printed circuit substrate, a second dielectric superstrate covering the top face of the first backgrounded dielectric substrate with the dielectric constant higher than that of the first dielectric substrate, and a low-profile radome having top and bottom sections that join together for waterproofingly housing the multi-layer printed circuit substrate assembly and antenna elements therein. The satellite patch antenna radiating elements arranged by two crossed couples which are connected to satellite antenna outputs through an active balanced feeder network with signal amplification.
