Title:
ANTENNA AND APPARATUS COMPRISING THIS ANTENNA
Document Type and Number:
WIPO Patent Application WO/2003/049227
Kind Code:
A1
Abstract:
An antenna with conductor elements (12) disposed in a matrix form consisting of lines and columns on a dielectric board (1) backed with a ground conductor plate (14). An individual conductor element (12) has a size insufficient to function as an antenna. A conductor element (12) is topped with a connection element (13) which overlaps two adjacent conductor elements (12). Some of the connection elements (13) bring conductor elements (12) on both sides in a continuity, and the other bring the conductor elements (12) on both sides in a discontinuity. The continuity and discontinuity between the conductor elements (12) are dynamically carried out by a switching device.
