Abstract:
Provided are a transmission/reception antenna and a transmission/reception device using the same wherein the transmission/reception antenna comprises an excitation loop antenna (12) having a loop of a single turn and a transmission/reception loop antenna (14) having a pair of loops (14a, 14b) of a plurality of turns which are closely wound around a magnetic member (11). The two loops of the transmission/reception loop antenna are located on either side of the excitation loop. A resonance capacitor (15) is connected across one ends of the two loops of the transmission/reception loop antenna, and a connecting portion (14c) is connected between the ends of the two loops opposite to those connected to the resonance capacitor. The frequency property is expanded without increasing the power consumption.
