Abstract

Improved communication performance is achieved in the case where a metal housing section with an insulation-treated surface is also used as a radio wave emission section. Electronic equipment according to the present technology includes a metal housing section, an antenna board, and an electrical coupling section. The metal housing section has an insulation-treated surface and constitutes at least part of the housing. The antenna board is located inside the metal housing section and has electrical circuitry formed thereon for controlling supply of power to an antenna. The electrical coupling section has a metal plate in contact with the metal housing section and performs electrical coupling between the antenna board and the metal housing section through capacitive coupling via the metal plate.

Claims

1. Electronic equipment comprising:

a metal housing section that has an insulation-treated surface and constitutes at least part of a housing;

an antenna board located inside the metal housing section, wherein the antenna board has electrical circuitry formed thereon for controlling supply of power to an antenna; and

an electrical coupling section having a metal plate in contact with the metal housing section, wherein the electrical coupling section performs electrical coupling between the antenna board and the metal housing section through capacitive coupling via the metal plate.

2. The electronic equipment according to claim 1, wherein

the electrical coupling section has a connection terminal for electrically connecting the antenna board and the metal plate, and

the metal plate is fixed to the metal housing section, and the connection terminal is fixed to the antenna board but not to the metal plate.

3. The electronic equipment according to claim 2, wherein

the connection terminal has a biasing force in a direction of approaching the metal plate.

4. The electronic equipment according to claim 1, comprising the antenna electrically connected to the antenna board, wherein

the electrical coupling section performs grounding of the antenna through the capacitive coupling via the metal plate.

5. The electronic equipment according to claim 1, wherein the electronic equipment is an imaging apparatus, wherein

the metal housing section has a grip frame section that constitutes an internal frame of a grip section having a shutter button and held by a user'"'"'s hand, and

the antenna board and the electrical coupling section are located inside the grip frame section.

6. The electronic equipment according to claim 5, wherein

the grip frame section is formed as a projecting portion having an edge on an imaging direction side protruding an the imaging direction, and
