Abstract
The invention relates to a printed antenna comprising a ground plane, a substrate stacked to the ground plane, a metal deposit made on the substrate in order to form therein a resonating patch (3), and a means of supplying to excite the resonating patch, characterized in that the patch has dimensions that are adapted for the patch to be able to radiate in both upper electromagnetic modes TM02 and TM20, and in that the means of supplying makes it possible to excite the patch on an excitation point (4) arranged along the patch so that the patch resonates in a single of said upper electromagnetic modes, by inducing this way a dual-beam radiation diagram with, in the same plane orthogonal to the patch, two main misaligned and symmetric lobes in relation to the normal to the patch.
