  • Array antenna
    Patent number: 6784835
    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.
    Type: Grant

  • Method and device for using array antenna to estimate location of source in near field
    Patent number: 6459409
    Abstract: An array antenna includes two sub-arrays. Each sub-array has at least three elements with at least one unshared element. Samplers sample elements separately for the sub-arrays. A direction-of-arrival estimator uses sampling from the samplers to make a separate direction-of-arrival estimate for each sub-array for direction of arrival of a signal from a source. A source location estimator estimates distances from the source to each element based on the separate direction-of-arrival estimates from the direction-of-arrival estimator. A sampling adjuster adjusts timing of sampling performed by the samplers based on the distances from the source location estimator.
