Abstract
An antenna (28) for use in a wireless communication module (10) includes a shield plate (40), an antenna loop element (42), and a transmission line element (44). The wireless communication module (10) also includes a receiver (37) having a circuit board (30). The shield plate (40) is located on a first side (32) of the circuit board (30); and the antenna loop element (42) and the transmission line element (44) are located on an opposite side (34) of the circuit board (30). The shield plate (40) is electrically connected to a first loop end (50) of the antenna loop element (42). A capacitor (64) interconnects a second loop end (52) of the antenna loop element (42) to a first transmission line end (58) of the transmission line element (44). A second transmission line end (60) is electrically open.
