1. A radiating element for an antenna system comprising:
- an antenna element having an aperture that extends into the antenna element, wherein the antenna element includes;
an aperture side defining an aperture area of the antenna element; and
at least two ridges which are each oriented about a center of the antenna element and are arranged in crosswise orientation with respect to the center of the antenna element;
a radiating element edge defining a rectangular contour that surrounds the antenna element on the aperture side; and
a single corrugation configured to separate, at least on the aperture side, the antenna element and the surrounding radiating element edge;
wherein;
the radiating element edge is connected to the antenna element at a distance greater than zero from the aperture side of the antenna element;
a width of the radiating element is less than λ
, where λ
is a wavelength of a center frequency in a used frequency band; and
the antenna element is centrally arranged within the contour.

Abstract
A radiating element may comprise an antenna element, a radiating element edge, and a corrugation. The antenna element may have an aperture that extends into the antenna element, and an aperture side defining an aperture area of the antenna element. The radiating element edge may surround the antenna element on the aperture side. The corrugation may be configured to separate, at least on the aperture side, the antenna element and the surrounding radiating element edge. The radiating element edge may be connected to the antenna element at a distance greater than zero from the aperture side of the antenna element.
