    摘要: In an antenna 1a for reader/writer of an interrogator in a non-contact data carrier system comprising the interrogator and a transponder, the antenna for reader/writer of the interrogator comprises a transmitting antenna 2 for transmitting a signal to the transponder and a receiving antenna 3 for receiving a signal from the transponder, and the receiving antenna 3 is a loop coil located at a position where magnetic fields of opposite polarities are induced in the receiving antenna 3 by magnetic coupling between the receiving antenna 3 and the transmitting antenna 2 and where the magnetic fields of opposite polarities cancel out each other. Preferably, the transmitting antenna 2 is comprised of at least two loop coils 2a, 2b for generating magnetic fields of opposite polarities to each other.

    摘要: A short-distance communication antenna (14, 16) can satisfactorily transmit and receive an information signal within a regulation range of the radio law. The short-distance communication antenna is provided on a card reader/writer (1) and enables the card reader/writer to communicate with a non-contacting information card (2) without being limited by the direction of the non-contacting information card upon reception. An embodiment of the antenna comprises a plurality of magnetic poles (40a, 40b), disposed on a magnetic member (40), to and from which a magnetic flux is transmitted and received. A coil (41) for transmitting and/or receiving the information signal is mounted on at least one of the magnetic poles. Another embodiment of the antenna includes a housing (335) having an aperture (334a) to and from which a magnetic flux is transmitted and received, and a coil (336), for transmitting and/or receiving the information signal, mounted on said housing. Furthermore, there are also provided methods of manufacturing and using the above short-distance communication antenna. The magnetic flux of the communication antenna is closed and a communication area is limited.
