Abstract:
An antenna system for use in a wireless communication system, comprising:an array of MÃ—N radiating elements for emitting a beam, M and N each being a positive integer, respectively; a feeding network for providing a plurality of signals to the array of MÃ—N radiating elements; M first phase shifters for steering the beam on the basis of column by phase shifting the plurality of signals from the feeding network; and N second phase shifters for steering the beam on the basis of row by phase shifting the plurality of signals from the feeding network, wherein the feeding network includes: an input port for receiving the plurality of signals; N dividers for transmitting the plurality of signals to each of transmission lines of the second phase shifters; and M combiner/dividers for transmitting the plurality of signals to each of transmission lines of the first phase shifters after passing through the second phase shifters.
