Abstract
An array antenna comprising a plurality of antenna elements, multipliers for multiplying coefficients with transmission or reception signal and a calculator for calculating the coefficients for each multiplier. The calculator generates the coefficients in a proposed method such that the beampattern of the array antenna has a flat top mainlobe with an adjustable beamwidth and a predetermined sidelobe ratio.
Claims3
