摘要： When a plurality of RW apparatuses are disposed in such a manner that the communication areas of adjacent RW apparatuses partially overlap each other, the polarized waves of the adjacent RW apparatuses are orthogonalized to each other and the tag switches the directions of the polarized waves with the movement of the tag. In this way, even when the communication area is expanded, signal crosstalk can be prevented.

摘要： A transponder of a communication system, which has a high modulation factor for stable communication. An impedance element in the form of a coil L1 is connected to an antenna 101 of the transponder 20, and a resistor R2 and a switching element in the form of a diode D2 a high-frequency wave of which is grounded are connected to the coil L1. The antenna 22 is a monopole antenna having a low impedance, and the coil L1 has an inductance of 10nH. Application of an electric current of 100mA to the diode D2 causes a phase difference of 122 degrees and an amplitude ratio of 1.1 with respect to a phase when the electric current is not applied to the diode.

摘要： The conventional technique in which transmission of an identification number from a responder to an interrogator is repeated bit by bit requires a complicated command structure, a large number of operation stages, a complicated flip-flop, switching control between transmission and reception, control of a memory address counter, and a complicated logical circuit such as a data comparison circuit, which increases the chip size in the responder. The present invention provides a responder and an interrogator for reading an identification number from the responder. When a clock pulse is modulated on a high-frequency carrier and transmitted to the responder from the antenna of the interrogator, there are a first case when the clock pulse interval is short and a second case when the clock pulse interval is long. By combining the clock pulses of the first case and the clock pulses of the second case so as to control the reading of the identification number by the interrogator, it is possible to realize reduction of the semiconductor chip size of the responder and reduce the costs of the semiconductor chip.

摘要： A radio interrogator system wherein even if a plurality of radio interrogators are disposed relatively close to each other and operated at the same time, the interference with radio responsors can be reduced and the throughput degradation in the whole system can be improved. The plurality of radio interrogators (100-1 to 100-4) are divided into two groups. It is arranged that the radio interrogators have operation mode establishing parts (51) that can establish, exclusively to the respective groups, either a transmission mode in which to transmit radio transmission signals to radio responsors (40-1 to 40-4) or a reception mode in which to receive radio response signals transmitted from the radio responsors in response to the radio transmission signals from the radio interrogators.

摘要： An ID tag capable of communicating data wirelessly, the size of which is reduced, and where the size of an IC chip is reduced, a limited area of the chip is effectively used, current consumption is reduced, and communication distance is prevented from decreasing. The ID tag of the invention includes an IC chip having an integrated circuit, a resonance capacitor portion and a storage capacitor portion, and an antenna formed over the IC chip so as to overlap at least partially with an insulating film interposed therebetween. The antenna, the insulating film and wirings or semiconductor films forming the integrated circuit are stacked, and one or both of capacitors in the resonance capacitor portion and the storage capacitor portion are formed by this stacked structure.
