Mobile communication handset
View Patent ↗An antenna module ( 5 ) is such that an antenna and two power supply points for that antenna are formed on a thin substrate. A substrate module ( 7 ) has a substrate, two power supply point contact units that respectively electrically contact the two power supply points attached to the substrate, and electronic components, and processes signals received via the power supply point contact units through a circuit formed by electronic components and the power supply contact units. A pressure plate ( 6 ) is positioned between the antenna module ( 5 ) and the substrate and anchors the antenna module ( 5 ) by pressing the entire surface of such against an outside case ( 20 ), excluding the power supply points, by the outside case ( 20 ) and an inside case ( 21 ) being fastened together.
1. A mobile communication handset comprising an antenna housing unit having:
an antenna module in which an antenna and two power supply points for said antenna are formed on a thin substrate;
a substrate module including a substrate, two power supply point contact units for electrically contacting said two power supply points, and electronic components, and comprising a circuit formed on said substrate and containing said electronic components and said power supply point contact unit attached on said substrate, said substrate module processing signals received from said circuit via said power supply point contact unit; and
an outside case and an inside case for housing said antenna module and said substrate module;
wherein said mobile communication handset comprises a pressure plate positioned between said antenna module and said substrate, and has openings for said power supply points positioned facing said power supply points, with the entire surface of said antenna module, with the exception of said power supply points, being pressed against and anchored to said outside case by fastening said outside case and said inside case together.
2. The mobile communication handset according to claim 1 , wherein said thin substrate is a flexible substrate.
3. The mobile communication handset according to claim 1 , further comprising built-in equipment positioned separated from said substrate;
wherein said pressure plate comprises a cable anchoring unit for anchoring the positions of cables linking said built-in equipment with circuits formed on said substrate.
4. The mobile communication handset according to claim 1 , wherein said openings for said power supply points are created independently with respect to said two power supply points and said pressure plate faces the part of said antenna module positioned between said two power supply points.
5. The mobile communication handset according to claim 1 , wherein said pressure plate has openings encompassing said electronic components at positions facing said electronic components arranged on said substrate.
6. The mobile communication handset according to claim 1 , wherein said pressure plate is formed of an insulator material.
7. The mobile communication handset according to claim 1 , wherein said pressure plate is formed of a magnetic material.
8. The mobile communication handset according to claim 1 , wherein said power supply point contact units are spring contacts.
9. The mobile communication handset according to claim 1 , wherein said power supply points are positioned toward the edge from the antenna axis of symmetry on the antenna formation surface of said antenna module.
10. The mobile communication handset according to claim 1 , wherein said antenna module comprises a magnetic sheet on a certain side of said substrate.
