Abstract
Planar antenna carried by a substrate comprising an annular slot, which is dimensioned to operate at a given frequency and which is fed via a line ( ), such as a microstrip line, in a short-circuit plane of which the slot is situated. The annulus formed by this slot ( ), is deformed as indentations in at least one zone of the plane in which the electric field is a minimum for the given frequency and a given mode, this making it possible to obtain a lengthening of the slot perimeter with respect to an annular slot ( ), of corresponding circular shape, without surface extension of the substrate zone wherein the slot is made.
