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.

The invention concerns an inhomogeneous lens with Maxwell's Fish-eye type gradient index (1), made in the shape of a hemisphere. The invention is characterized in that the lens comprises N hemispheric concentric shells (2 to 4), with different discrete dielectric constants and mutually interlaced without void between the two successive shells, with 3≦N≦20, the discrete dielectric constants of the N shells being such that they define a discrete distribution close to the theoretical distribution of the index inside the lens.

摘要:
A broadband array antenna which delivers an axisymmetric main lobe. The antenna includes patches arranged with an interruption of periodicity in one of the planes and is corner-fed by tree like feed lines from a central point of energization. Opposite each path is a parasitic element for broadening the band. This device can be used in particular with measurement radar.
