Abstract
A microwave antenna element comprising a ground plane printed on an insulating substrate and an antenna plate having at least one antenna outlet. The ground plane and the antenna plate are separated by a dielectric, wherein the dielectric separating the plate from the ground plane is air. The antenna plate is constituted by a conductive plate of a shape adapted to the polarization of the transmission microwave vector. The antenna plate has at least two legs formed by stamping and folding which serve to support the plate on the substrate. Each leg passes through a respective orifice in the substrate, at least one of the legs serves not only for support purposes, but also constitutes an antenna outlet. There is a gap in the ground plane surrounding the orifice via which each leg of the antenna outlet passes through the substrate.
