Title:
METHODS AND APPARATUS FOR GENERATING BEAM PATTERN WITH WIDER BEAM WIDTH IN PHASED ANTENNA ARRAY
Document Type and Number:
WIPO Patent Application WO/2017/193953
Kind Code:
A1
Abstract:
A method of steering beam direction and shaping beamwidth of a directional beam using a phased antenna array in a beamforming cellular system is proposed. The N antenna elements of the phased antenna array are applied with a set of combined beam coefficients to steer the direction of the beam and to shape the beamwidth to a desired width. Specifically, in addition to the original constant phase shift values, additional phase modulations are applied to expand the beam to a desirable width. The phased antenna array applied with the combined beam coefficients involve only phase shift, no amplitude modulation is needed and thereby increasing beamforming gain and efficiency.
