摘要: A disclosed RF tag reader includes a main antenna with directivity covering a first area; a sub antenna with directivity covering a second area that is smaller than the first area; and a switch control unit configured to selectively switch between the main antenna and the sub antenna. In response to receiving an answer signal via the sub antenna from a wireless communications unit moving together with one or more management objects, the switch control unit switches an antenna used for communications from the sub antenna to the main antenna and the RF tag reader performs communications, via the main antenna, with an RF tag each accompanying one of the management objects.

摘要: The present invention relates to a tag-use antenna allowing a miniaturization while maintaining a constant minimal change of a communication distance. The tag-use antenna has a feed part of a folded dipole antenna of a size of 53 mm long and 7 mm wide being connected to, and equipped with, an LSI chip of Rc=500 ohms and Cc=1.4 pF and is covered with plastic resin 13 of the dielectric constant εr=3 and thickness of t=0.75 mm on both sides of the antenna. The dipole part of 1 mm wire path width of the tag-use antenna is formed in a rectangular spiral by being bent inward from both ends at bending parts at four places. The entire length of the dipole antenna when extending the four bending parts straight is featured so as to be shorter than one half of a resonance wavelength of the antenna. An inductance part is featured in the intermediate part of the both dipole parts in the neighborhood of the center of the antenna. The inductance part is connected to the chip equipment part in parallel with the both dipole parts.

摘要: A reader/writer 25 transmits an instruction for changing over between antennas 31 and 32, carried on a high frequency wave in the same format as a common command. A part of the antenna is equipped with a command interpretation circuit 30 which demodulates a high frequency wave received from the reader/writer body 25 and obtains a command content. If this command is an antenna changeover instruction of the reader/writer itself, the command interpretation circuit 30 instructs a changeover signal generation unit 28 for generating a changeover signal and changes over antennas by controlling a high frequency wave switch unit 29.

摘要: Distortion compensation coefficients for correcting distortion of a transmission power amplifier are stored in a memory beforehand, a distortion compensation coefficient conforming to powers or amplitudes of a present transmit signal and a past transmit signal is read out of the memory, and distortion compensation processing is applied to the transmit signal using this distortion compensation coefficient. The transmit signal thus subjected to distortion compensation processing is then amplified by the transmission power amplifier and the amplified signal is transmitted, and the distortion compensation coefficient is updated based upon the transmit signal before distortion compensation and an output signal from the transmission power amplifier.

摘要: In a predistorter, an input signal to be inputted into an amplifier is in advance modified by a reverse characteristic of an input-to-output characteristic of the amplifier. The predistorter determines correction coefficients corresponding to one or both of a differential and an integral of the input signal so as to further modify the input signal into a final predistortion signal according to the modified input signal and the correction coefficients.
