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 () having a loop of a single turn and a transmission/reception loop antenna () having a pair of loops () of a plurality of turns which are closely wound around a magnetic member (). The two loops of the transmission/reception loop antenna are located on either side of the excitation loop. A resonance capacitor () is connected across one ends of the two loops of the transmission/reception loop antenna, and a connecting portion () 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.
