ABSTRACT:
Antenna systems, in particular but not exclusively, for use in base transceiver stations of wireless telecommunication networks. Specifically, the present invention combines two or more wide-beam antennas to generate relatively narrow beams and can be used in any sectorized wireless network such as, but not limited to, GSM, CDMA, TDMA and UMTS. Illustratively, two electrically separated beams, creating two electrically separated sectors, can be formed with both beams having characteristics of a combined antenna but advantageously generated using only half the number of separate antennas than conventionally taught to achieve the same beam width for each sector.
