Abstract
Portable radio equipment which is thin enough to enhance portability and, yet, has a sufficiently high antenna gain. The equipment has an antenna which is made up of a pair of metal plates located face-to-face, and a short-circuiting member for short-circuiting the metal plates. A circuit board loaded with radio circuitry is interposed between two metal plates with the radio circuitry being connected to the antenna. A capacitor is connected between the metal plates to lower the resonance frequency of the antenna, as needed. A circular cell for powering the equipment is located in a cell receiving portion near the short-circuiting member.
