Abstract
A phased array antenna system with electrical tilt control incorporates a tilt controller () for splitting an input signal into three intermediate signals, two of which are delayed by variable delays Tand Trelative to the third. A corporate feed () contains splitters Sto Sand hybrids Hto Hfor processing the intermediate signals to produce drive signals for elements of an antenna array (); the drive signals are fractions and vector combinations of the intermediate signals. The tilt controller () and the corporate feed () in combination impose relative phasing on the drive signals as appropriate for phased array beam steering in response to variable delay of two intermediate signals relative to the third intermediate signal.
