ABSTRACT:
This antenna array for base station for radiocommunication with mobiles comprises N first sensors, N being an integer greater than 2, arranged in such a way that the array exhibits substantially no ambiguity; an (N+1).sup.th sensor placed or contrived in such a way as to receive signals which are decorrelated from the previous ones; and a module for processing the signals received, making it possible to locate, in an explicit or implicit manner, a transmitting mobile from the signals received by the N sensors alone, and to combine these signals and the signals received by the (N+1).sup.th sensor so as to improve reception by effecting spatial or spatio-temporal diversity.
