PROBLEM TO BE SOLVED: To provide a compact high-gain antenna assembly usable for radiotelephones for mobile communications, etc., which is usable close to a human body, easy to adjust the antenna impedance and less in secular change of the shape. SOLUTION: The antenna assembly comprises a non-conductor formed part 4 on a part of a ground plane, and an antenna plate composed of an insulating resin board on the upside of the formed part 4. A ground plate is mounted on the downside of the formed part 5. A first high-frequency circuit 12, a cell, etc., are mounted on the upside and the downside of the ground plane, except the non-conductor formed part 4. COPYRIGHT: (C)2003,JPO
