ABSTRACT:
An improved, compact, lightweight handy-phone provided with a built-in directional planar antenna is provided. The planar antenna is mounted on a portion of a high-frequency printed wiring board, and a shielding case covers the high-frequency printed wiring board with a surface of the portion exposed. A maximum linear size of the shielding case in the direction of main polarization of the planar antenna is nearly equal to half the wavelength of an electromagnetic wave to be radiated by the planar antenna.
