ABSTRACT:
An antenna system for a communication receiver (100) which has an internal antenna (200) and which is coupled to a portable computer (104) to deliver received data messages thereto comprises a resonant loop antenna (16) magnetically coupled to the internal antenna (200) of the communication receiver (100), and a resonant wireframe shield (18, 40) which is coupled to the resonant loop antenna (16) and oriented perpendicular thereto. The resonant wireframe shield (18, 40) shields the communication receiver (100) from an electrical interference signal generated by the portable computer (104).
