ANTENNA-EQUIPPED PRINTED CIRCUIT BOARD

摘要

A printed circuit board (50) includes a chip-shaped printed antenna (10) having an open end formed by at least two antenna conductors arranged separately from each other. As shown by a hatched portion, on the printed circuit board (50), a ground required by one or more other modules is arranged so as to surround a region around the printed antenna (10) excluding a certain region. Thus, on the printed circuit board (50), the radiation electric field does not become a dipole mode but is formed to discharge in one direction in a balloon shape as shown by a broken line.
