Abstract

The electronic equipment includes a housing accommodating an electronic circuit used in the operation of the device and a high-frequency circuit for wireless communication related to the operation of the device. A dielectric antenna is mounted on the rear surface of the housing near a lateral end thereof. Since the electronic circuit for operation and the high-frequency circuit for wireless communication are provided in the housing, it is not necessary to connect a personal computer and a mobile telephone by a cable thus making the device mobile. Further, since the dielectric antenna connected to the high-frequency circuit is mounted on the rear surface of the housing, the antenna characteristics can be improved and stabilized.
