1. A wireless network card comprising:
- a board on which an electronic circuit unit is arranged;
a radiating element provided on one side of the board;
a feeding line provided on one surface of the board, one end of the feeding line being connected to the electronic circuit unit and another end of the feeding line being connected to the radiating element; and
a ground conductor pattern, serving as a ground of the radiating element, provided on another surface of the board to face at least the feeding line via the board, wherein an elongated hole is formed in a region of the ground conductor pattern that does not overlap the feeding line, between the electronic circuit unit and the radiating conductor pattern to form a choking slit, and the choking slit has a length of about ½
of a wavelength λ
of a tuning radio wave in which the radiating element resonates.

Abstract
A wireless network card contains a card-shaped board on which an electronic circuit unit is arranged; radiating conductor patterns and feeding lines that are provided on one surface of the board; a ground conductor patterns, serving as a ground of the radiating conductor patterns, provided on the other surface of the board. Also, choking slits set to have a length that makes it difficult for a high-frequency current to flow through the electronic circuit unit are formed in a region of the ground conductor pattern that does not overlap the feeding lines, between the electronic circuit unit and the radiating conductor patterns.
