Active antenna arrays
First Claim
1. An antenna array, adapted for use with a plurality of different mobile telecommunications systems, comprising:
- a plurality of antenna elements, which are divided into a plurality of antenna groups, the groups comprising more than one antenna element;
a plurality of feeding and phase shifting networks;
wherein the antenna array is an active antenna array, and includes a plurality of transceivers, which are divided into a plurality of transceiver sets, the sets comprising more than one transceiver, and wherein the transceivers are configured to operate on a respective mobile telecommunications system of said plurality of different systems;
wherein at least one transceiver set is coupled through a respective feeding and phase shifting network to a respective antenna group, so that the transceivers of the at least one transceiver set are coupled to the antenna elements of the respective antenna group in order to provide an active antenna array, generating a predetermined phase progression of antenna signal across adjacent elements of said plurality of antenna elements.
