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.

An antenna unit of a central station of a point-to-multipoint radio relay system,
- the antenna unit defining a predetermined plurality of fixed sectors emanating radially therefrom, a first portion of the sectors being transmissions sectors and a second portion of the sectors being non-transmission sectors, each of the sectors being restricted to a predetermined area as a function of a respective direction and a respective opening angle thereof, wherein the direction and opening angle of each of the transmission sectors is defined based on a location of one or more of a plurality of fixed subscriber stations, each of the non-transmission sectors including no subscriber stations therein.
