Abstract

An improved antenna arrangement includes a reflector arrangement comprising a printed circuit board with an electrically conductive ground plane. The reflector arrangement also has a reflector frame with a coupling surface. The coupling surface is capacitively coupled to the ground plane. The coupling surface has a recess via which the ground plane, which is located underneath it, and/or the printed circuit board or an isolating intermediate layer which is provided above the ground plane or an isolating intermediate layer which is provided above the printed circuit board is exposed. The at least one antenna element arrangement is positioned and/or held on the printed circuit board in the area of the recess.
