Energy saving by the use of active phased-array antennas
Abstract
The energy saving of active transmitter-receiver phased-antenna arrays as compared with passive arrays is determined. The energy saving is maximal for the case of maximal losses in the feed system, minimum noise temperature of the amplifiers and radiators, and maximal gain coefficient of the transmitter power-amplifiers. It is found that the active-array synthesis can be simplified significantly, without a decrease in energy saving, by reducing the number of active amplifiers.
