PORTABLE WIRELESS DEVICE

摘要

Provided is a portable wireless device having a plurality of antennas of different frequency bands. By positively using one antenna for improving gains of other antennas, the one antenna can be effectively used and the gains of other antennas can be improved. Patterns (A1, A2, A3, B1, B2, B3) for adding a band disturbing element (80) (high frequency blocking means), which is composed of beads and a parallel resonance circuit, are arranged at a prescribed position of a magnetic field antenna (50). The band disturbing element (80) may be composed of ferrite core or the like.
