Abstract

The electronic equipment according to the present invention is adapted to be operated by an operator in facing positional relationship therewith. This electronic equipment includes a housing accommodating an electronic circuit for operation and a high-frequency circuit for wireless communication related to the operation, and a dielectric antenna connected to the high-frequency circuit. The 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 according to predetermined specifications as in the prior art, so that it is possible to provide electronic equipment which can be easily used as a mobile terminal. Further, since the dielectric antenna connected to the high-frequency circuit is mounted on the rear surface of the housing near a lateral end thereof, the antenna characteristics can be improved and stabilized.
