PRINCIPLE OF PHASESHIFTERSMovement
of Dielectric
Commercial In Confidence 17
PHASE SHIFTER Allows for wide range of downtilt;
typically 10 degrees, but 20 degrees also available in special antennas
Continuous (not stepped) phase
Independent control of element amplitude/phase allows superior vertical pattern stability
Can provide nullfill
Robust, field proven, simple
Fewer interconnects
Competitors antennas fed in pairs Inherent phase deviation from linear
gradient Lose control of sidelobes and nullfill
