Abstract
An antenna system (10) comprises a transmitter part (12) comprising n inputs (40.1 to 40.n) to the antenna system, a transmitter part antenna array 18 comprising k radiating elements; a respective beam-forming network (20.1 to 20.n) connected to each of the n inputs with each beam-forming network having a plurality of outputs; and k signal combiners (22.1 to 22.k) each having a plurality of inputs and a respective output. Each output of each beam-forming network is connected to a respective input of each of the signal combiners and the output of each signal combiner is connected via an output stage to a respective one of the k radiating elements. The beam-forming networks are configured such that each of the transmitter part inputs is associated with a respective transmitter part beam (24.1 to 24.n) having a respective beam-width.
