Abstract: To enable the antenna of a central station of a point-to-multipoint radio relay system to be operated with as little transmitting power as possible and to assure high transmission quality, the antenna produces a characteristic composed of a plurality of sectors which are so designed with regard to their direction and their opening angle that each individual sector is restricted as narrowly as possible to the area occupied by one or a plurality of subscriber stations.

Abstract: A headlight with an integrated microwave antenna is provided with a rotationally-symmetrical, paraboloid reflector (21) and direct, lateral radiation of the microwaves. An electrical feeder element (15) is disposed to the side of the reflector (21) and, seen in the radiation direction (14), with suitable spacing in front of a light source (13). The arrangement of the feeder element (15) of the microwave system according to some embodiments is such that the radar beam is directed and bundled over the upper half of the reflector. The beam path for the light source is represented by the respective edge beams (131) and (132). The beam path for the feeder element (15) of the microwave system is represented by the respective edge beams (151) and (152). The optical system with its light source (13) and the microwave system with its feeder element (15) and/or receiver element are functionally and spatially configured and disposed completely separately from one another.
