    摘要: A method of controlling an active antenna comprising a matrix of individual transmitting/receiving elements. Two optical frequencies are superposed to generate an optical beat signal in the microwave frequency range. After electrical/optical conversion the beat signal is fed with a defined phase and amplitude to the individual transmitting/receiving elements of the antenna.
