Abstract

An antenna has an antenna body having a plurality of first antenna elements situated along a first straight line. The antenna body includes a first conductive grounded surface and a second conductive grounded surface, the first and second grounded surfaces being situated essentially parallel to one another. A dielectric is situated between the first and second grounded surfaces. A signal conductor is also situated between the first and second grounded surfaces. The first antenna elements are designed as apertures situated above the signal conductor in the first grounded surface. Furthermore, the antenna is designed to emit a signal in a direction in space, depending on a frequency of the signal. At least two of the first antenna elements differ from one another in such a way that their power emissions are different.
