Title:
COMMUNICATIONS SYSTEM INCLUDING PHASED ARRAY ANTENNA PROVIDING NULLING AND RELATED METHODS
Document Type and Number:
WIPO Patent Application WO2006009601
Kind Code:
A3
Abstract:
A phased array antenna (22) may include a plurality of antenna elements (23), at least one respective phase shifter (24) connected to each antenna element, and at least one respective gain element (25) connected to each antenna element. The phased array antenna (22) may further include at least one controller (26) for determining and controlling both phases and gains of the phase shifters (24) and gain elements (25), respectively, to provide beamsteering in a first direction for a signal of interest (30). The controller (26) may also iteratively determine and control phases of the phase shifters (24) to provide a null in a second direction for a signal not of interest (31), and without determining or controlling gains of the gain elements (25).
