摘要：An antenna system for use in an electronic security system and having atransmitting antenna with at least one loop lying in a plane, and a receiving antennahaving at least two twisted loops lying in a common plane with each loop being twisted180° and in phase opposition with each adjacent loop. The transmitting and receivingantennas are disposed in spaced substantially parallel relationship across an aisle orpassage through which a resonant tag circuit must pass for detection.
