Title:
BOARD
Document Type and Number:
Japanese Patent JP2002021215
Kind Code:
A
Abstract:
To solve the problem that a conventional board depends upon absorption by heat loss at a time when electromagnetic waves flow in a conductive material used for an antenna as a current because linear antennas are brought to a mutually independent state and excellent electromagnetic-wave absorption efficiency is not necessarily excellent.
The board has an electromagnetic absorption member (a finishing material 3), in which the antennas 5 formed by electrically connecting a plurality of mutual linear antenna elements 5a by connecting patterns 5b are formed, and the board in which the connecting patterns 5b have connecting end sections 5j for connecting one ends of ground cables 5e is provided.
