Abstract
The present invention relates to a planar antenna carried by a substrate including a slot ( ) consisting of a closed curve dimensioned in order to operate at a given frequency and fed by a feed line ( ) positioned so that the slot lies in a short-circuit plane of the feed line. This antenna includes, in parallel on the slot , at least one switching means capable of assuming a closed state or an open state so as to modify the operating frequency band of the planar antenna. This antenna is particularly suitable for domestic wireless networks.
