Abstract:
1. A transmission/reception antenna, comprising: a magnetic member; an excitation loop antenna disposed on the magnetic member; a pair of transmission processing unit connecting terminals connected to the excitation loop antenna and configured to be connected to a transmission processing unit; a transmission/reception loop antenna disposed on the magnetic member adjacent to but not in contact with the excitation loop antenna, and including a first loop of a plurality of turns, a second loop of a plurality of turns and a connecting portion connecting one end of the first loop to one end of the second loop; a pair of reception processing unit connecting terminals connected to opposite ends of the first and second loops to the one ends thereof and configured to be connected to a reception processing unit; and a resonance capacitor connected between the opposite ends of the first and second loops of the transmission/reception loop antenna; wherein the first and second loops of the transmission/reception loop antenna are located on either side of the excitation loop antenna, and wherein the transmission processing unit connecting terminals are located on either side of the resonance capacitor.
