Abstract

There are included a housing 8, an antenna structure, a slot 10 of the housing into which a PC card is inserted, a high frequency cable 5 one end of which is connected to the antenna structure electrically and part of which is pulled outside the housing, a connector plug 6 that is connected to the other end of the high frequency cable 5 electrically and is outside the housing, and an elastic body such as rubber 13 which is configured so that the high frequency cable is pulled inside the housing.

Claims

1. A computer system comprising:

an antenna structure;

a slot of the computer system into which a PC card is inserted;

a spring terminal connected to the antenna structure electrically, wherein the computer system is configured so that the spring terminal contacts to the outside of a housing of the PC card by the PC card being inserted into the slot; and

a coaxial high frequency cable one end of which is connected to the antenna structure and the other end of which is connected to a printed circuit board, wherein a wiring pattern on the printed circuit board to connect the high frequency cable to the spring terminal has a first pattern connected to a central conductor of the high frequency cable and a second pattern that surrounds the first pattern and is connected to a peripheral conductor of the high frequency cable.

2. The computer system according to claim 1, comprising a pad terminal, connected to a high frequency module, outside a housing of the PC card, wherein the spring terminal contacts to the pad terminal by the PC card being inserted into the slot so as to electrically connect said high frequency module to said antenna structure.

3. The computer system according to claim 1, wherein the computer system is a notebook type computer system.

4. A connecting structure between a PC card and a computer system, comprising:

a spring terminal that is provided in the vicinity of a PC card slot of the computer system and is connected to an antenna structure electrically; and

a pad terminal that is provided outside a housing of the PC card and is connected to a high frequency module electrically, wherein the connecting structure is configured so that the spring terminal contacts to the pad terminal by the PC card being inserted in the PC card slot.

5. The connecting structure according to claim 4, wherein the pad terminal is located along an edge of the housing that is perpendicular to an insertion travel direction of the PC card.

6. The connecting structure according to claim 4, wherein said pad terminal is mechanically rubbed with said spring terminal by said PC card being inserted into said PC card slot.

7. A PC card comprising a pad terminal that is formed on a surface of a housing of the PC card and is connected to a high frequency module electrically, wherein the PC card is configured so that the pad terminal is connected to a spring terminal, which is provided in the vicinity of the PC card slot and is connected to an antenna structure electrically, by a PC card being inserted into the PC card slot of a computer system.

8. The PC card according to claim 7, wherein the surface is an edge of the housing that is perpendicular to an insertion travel direction of the PC card.

9. The connecting structure according to claim 7, wherein said pad terminal is mechanically rubbed with said spring terminal by said PC card being inserted into said PC card slot.

10. A computer system comprising:

an antenna structure disposed inside the computer system

a slot of the computer system into which a card is inserted;

a spring terminal connected to the antenna structure electrically, wherein the computer system is configured so that the spring terminal contacts to the outside of a housing of the card by the card being inserted into the slot; and

a coaxial high frequency cable one end of which is connected to the antenna structure and the other end of which is connected to a printed circuit board, wherein a wiring pattern on the printed circuit board to connect the spring terminal comprises a first pattern to connect to a central conductor of the high frequency cable and a second ground plane pattern connected to peripheral conductor of the high frequency cable.
