Abstract
Since signal transmittance adjustment devices that can suppress transmittance of a receiving signal to a DSP as a receiving processing device from an antenna for reception and a signal transmittance control device configured to control the signal transmittance adjustment devices so that the transmittance of the receiving signal to the DSP from the antenna for reception is suppressed at least when a transmission signal including a modulation signal is transmitted from an antenna for transmission are provided, occurrence of a trouble in which a head portion of a reply signal is crushed by a wrap around signal from a transmission side can be suitably prevented, and particularly, favorable communication can be realized at start of a response from a RFID tag. That is, an apparatus for communicating with a RFID tag that can suitably suppress an influence of a transient response can be provided.
