INTEGRATED AND PHASE-COMPENSATED BASE STATION ANTENNA PHASE SHIFTER AND CALIBRATION BOARD

Disclosed is an antenna having a plurality of radiator columns and an integrated phase shifter/calibration board. The radiator columns have radiator clusters that may be differentially phase to provide beam tilt. The input traces of each of the phase shifters is capacitively coupled to a Wilkinson power divider that sums the power of all the input signals, thereby providing a calibration function. The output traces of each of the phase shifters has a designated meander pattern that provides phase alignment for all the output signals to prevent phase mismatches between signals fed to the radiator clusters.
