A comparative evaluation of the architectures of transmit phased-array antennas in terms of efficiency
Abstract
Three basic architectures of phased arrays based on a parallel excitation scheme with binary power division are compared to determine which has the highest efficiency. The efficiencies of the phased arrays considered are plotted as a function of the efficiency of the active element and as a function of the power gain. A plot of the array efficiency vs. the point of connection of the active element is also presented.
