PROBLEM TO BE SOLVED: To provide a non-contact information recording medium and a gate system, which can suppress the interference between a power carrier and a data carrier to be small and which can miniaturize two antennas on adopting a two wave system which can suppress an effect on other radio system. SOLUTION: In an automatic ticket examination device, a loop-like power transmission antenna is arranged at prescribed intervals from the upper surface of a main body and a loop-like data transmission/reception antenna is arranged almost concentrically with the power transmission antenna. In a radio card P, a loop-like data transmission/reception antenna 42 is arranged almost concentrically with the power reception antenna 41 on the inner side of the loop-like power reception antenna 41. Various capacitors constituting the radio transmission/reception part of the radio card are formed to be thin film forms and they are incorporated in a mounting substrate 43. |
