In order to extend the scanning range of a phased array and maintain the scanning gain flatness, a novel millimeter-wave phased array with four linearly-arranged pattern reconfigurable elements is presented in this communication. The phased array has been designed, fabricated, measured and analyzed. The active patterns of each reconfigurable element are measured at different reconfigurable modes and...
Beamsteering for a phased array antenna generally causes the sidelobe level deterioration due to a variety of random and spatially correlated errors. Conventional array error analysis method is based on probability central limit theorem, and can be calculated by the probability statistic approach. In the paper, this reaserch presents a new estimation method of the phased array patterns by using numerical...
