ABSTRACT:
An antenna assembly, and an associated method, facilitates communication of a radiotelephone operable in a satellite communication system, such as a satellite-cellular communication system. A patch antenna is rotatably coupled to a radiotelephonic housing of the radiotelephone. The patch antenna exhibits circular polarization characteristics, best to detect and to transmit communication signals to a satellite-based transceiver. By positioning patch antennas at opposing sides of the radiotelephone, down-link signals transmitted to the radiotelephone are detectable irrespective of the orientation of the radiotelephone.
