Claim Text:
1. A communication terminal device comprising: a UHF-band RFID system including a wireless IC element for UHF-band RFID and a loop-shaped conductor coupled to the wireless IC element for UHF-band RFID; and a UHF-band mobile communication system including a wireless IC element for UHF-band mobile communication and an antenna conductor coupled to the wireless IC element for UHF-band mobile communication; wherein the loop-shaped conductor is coupled to a ground conductor provided in a case of the communication terminal device; the wireless IC element for UHF-band mobile communication is coupled to the ground conductor; the loop-shaped conductor and the antenna conductor are closely adjacent to each other, and the loop-shaped conductor is electromagnetically coupled to a portion of the antenna conductor; the loop-shaped conductor is arranged on a feeding portion side of the antenna conductor relative to a longitudinal center of the antenna conductor; the antenna conductor includes a first radiating portion and a second radiating portion, the second radiating portion being configured to radiate and/or receive a high frequency signal in a frequency band which is different from that of a high frequency signal that the first radiating portion is capable of radiating and/or receiving; and the loop-shaped conductor is electromagnetically coupled to one of the first radiating portion and the second radiating portion of the antenna conductor which is configured to radiate and/or receive a high frequency signal near a UHF band.
