PROBLEM TO BE SOLVED: To provide an antenna for inductive radio, capable of saving space, preventing a disconnected point, and improving efficiency. SOLUTION: In order to prevent loop antennas 11, 12 from interfering with each other, partial parts of them are superposed on each other. A phase shifter 13 is installed between the loop antennas 11, 12 and a synthesization/distribution part 14 to shift the phase between the loop antennas 11, 12 byπ/2. COPYRIGHT: (C)2011,JPO&INPIT |
