Abstract
An information processing apparatus has a transmission antenna and a reception antenna and performs radio transmission/reception with a radio card via the two antennas, thereby performing predetermined information processing. Each of the transmission antenna and reception antenna is formed of a loop antenna. Both antennas are made to overlap each other by a predetermined length so as to prevent mutual electromagnetic interference and are situated in substantially the same plane. Accordingly, even if the transmission antenna and reception antenna are situated close to each other, a signal radiated from the transmission antenna is prevented from interfering with the reception antenna. Thus, the reception antenna can surely receive only a signal radiated from the radio card or an object of communication.
