Abstract

An electronic device for wireless communications, which may typically be a PC card 21, is adapted to upwardly turn the direction of radiation of the radio wave radiated from an antenna regardless of the mounted position of the antenna. The PC card 21 is contained in or removably fitted to a personal computer 11 so as to provide the personal computer 11 with wireless communication functions. The PC card 21 comprises amounting base board 24 fitted to the personal computer 11 with an end thereof projecting from the personal computer 11 and mounting a wireless 10 circuit, at least a chip antenna 23 arranged at the projecting region of the mounting base board 24 and electronically connected to the wireless circuit and a reflector 28 arranged below the chip antenna 23 and a housing covering the mounting base board 24, and adapted to upwardly reflect at least part of the radio wave that is radiated from the chip antenna 23 and directed downward.

Description

technical field [0001] The present invention relates to an electronic device for wireless communication, such as a wireless communication card, which provides wireless communication functions for electronic equipment, such as a personal computer. More particularly, the present invention relates to a technique applicable to improving radiation characteristics of an antenna arranged in an electronic device for wireless communication. Background technique [0002] Currently, electronic devices including personal computers can be wirelessly connected to peripheral devices including printers, and can also be connected to communication networks such as the Internet through wireless LANs (Local Area Networks) for greater convenience. [0003] Devices for providing communication functions for electronic equipment include externally attachable electronic devices for wireless communication, such as wireless communication cards, such as PC cards, CF cards, SD cards, and USB adapters, a...
