Abstract
A portable wireless device includes a first communication unit having a loop antenna that communicates with external devices using a first usable frequency band, and an RFID chip that performs predetermined processing with respect to information communicated by the loop antenna. A second communication unit includes a main antenna that communicates by a second usable frequency band that is higher than the first usable frequency band, and a communication processing unit that performs predetermined processing with respect to information communicated by the main antenna. A reactance component of the loop antenna is adjusted such that a high-order secondary resonance point of the first usable frequency band does not overlap the second usable frequency band.
