ABSTRACT:
Antenna arrays with more than one radiating element often require a calibration or adaptive technique to monitor the individual antenna currents and provide some form of correction. This invention is directed to a system of directional couplers and transmission lines usually placed between the transmitter and element matching network that develops a signal which is proportional to the actual antenna element radiating current. This includes mismatches and mutual impedance effects. A knowledge of the matching network is required. The system can be used in any guided transmission line system (i.e., waveguide, coax, stripline, microstrip, etc.)
