Abstract
Antenna array calibration systems and related methods include or utilize a plurality of signal splitter/combiner networks. Each of the signal splitter/combiner networks has a calibration signal sampling point in electrical communication with a signal input point, and signal output points. Each calibration signal sampling point may be capacitively coupled to a respective calibration source input of a calibration network. The signal splitter/combiner networks may be formed as phase-shifting networks.
