ABSTRACT:
A built-in antenna mounting structure for portable radio equipment, including a shield chassis formed of molded resin, whose surface except an antenna mounting surface is treated with a conductive material, a printed wiring board mounted on the shield chassis and having a transmitting/receiving circuit, and a built-in antenna formed from a metal plate and mounted on the antenna mounting surface of the shield chassis. The built-in antenna has a platelike antenna element and an elastic short-circuit plate for short-circuiting the antenna element to the shield chassis. The shield chassis is held at an edge portion thereof between the short-circuit plate and the antenna element, thereby mounting the built-in antenna on the shield chassis.
