Abstract:

Id ntifiers upergain antennas. Power gain and effective noise temperature of an antennafier in which an amplifier is connected to each antenna element are discussed. The derived equations for power gain and effective noise temperature may be used to select parameters for optimizing the performance of an antennafier. A supergain antennafier array is proposed and some theoretical patterns of supergain arrays are presented. The problem of excitation accuracy is considered briefly. Author
