Abstract
Compact, planar antenna made on a substrate comprising an annular slot which is dimensioned to operate at a given frequency and which is placed in a short-circuit plane of a line via which the antenna slot is fed. A second slot feed line is symmetrically disposed with respect to the first line in the line short-circuit plane common to them. Each of the lines, furnished with a port, is connected to a switching facility so as to allow the feeding of the antenna through one or the other of the two ports.
