Delay Insensitive Signal-Injection Calibration for Large Antenna Arrays Using Passive Hierarchical Networks

Efficient beamforming of phased-array antennas requires that the phase delay of each channel is accurately known. One technique for achieving this is to distribute a calibration or local-oscillator reference signal through a delay-insensitive signal distribution network. In this paper, we propose us...
