ABSTRACT:
A low profile antenna system comprises a frame having front and side surfaces for enclosing a printed circuit board supporting a receiver, the front surface of the frame including a first conductive plate, an isolated portion thereof, which couples to the printed circuit board and forms a first portion of a loop antenna. A conductor is coupled to the printed circuit board and forms a second portion of the loop antenna. A second conductive plate is coupled to the frame and forms a rear surface of the frame to completely enclose the printed circuit board. The second conductive plate is capacitively coupled to the conductor thereby enhancing the sensitivity of the loop antenna.
