Abstract
The present invention relates to a planar antenna carried by a substrate comprising a slot in the form of a closed curve dimensioned to operate at a given frequency, supplied by a feeder line intersecting the slot at a point known as an excitation point, characterized in that at least two short circuits in parallel on the slot are positioned with respect to the excitation point so as to match the impedance to the excitation point and/or the polarization of the antenna.
