Abstract
A portable receiving antenna system for providing communication with a transmitting station carried by a geostationary satellite. The system includes a portable case, a flat plate antenna arranged to cover an opening of the portable case, and an adjustable support arranged within the portable case to support the flat plate antenna at an incident angle capable of receiving electromagnetic waves from the transmitting station. The flat plate antenna is in the form of a micro strip line slot array antenna including a dielectric layer, a metallic earth film formed with a plurality of spaced slots and secured to the surface of the dielectric layer in such a manner that the slots are arranged to receive the electromagnetic waves from the transmitting station, and a feeder line circuit secured to the rear surface of the dielectric layer. Preferably, an azimuth compass and a converter are mounted within the portable case, the converter being connected to an output terminal of the feeder line circuit.
