Abstract
An antenna has a ground plane and a radiating element supported in electrically insulated, closely spaced-apart relation to the ground plane. Electrical energy is fed to the radiating element for radiation therefrom. The radiating element is constructed so as to lengthen at least one effective electrical dimension of the radiating element relative to a corresponding dimension of an orthogonal projection of the radiating element onto a plane parallel to the ground plane. In the preferred embodiment, the radiating element has a central plane portion substantially parallel to the ground plane, an outer flange portion extending towards the ground plane, and a square cutout centered with respect to the central plane portion.
