The Keysight 85571A-028 is a 64-element phased array antenna designed for 5G air interface testing and measurement across the 27.5 to 30.0 GHz frequency band. This 8×8 planar array delivers individually calibrated elements with magnitude and phase control, enabling precise beamforming and signal analysis in the 28 GHz spectrum. The antenna features azimuth beam sweep from −60 to +60 degrees and elevation sweep capability with 1-degree resolution, supporting multiple beam widths for channel equalization, RF probing, and signal-to-noise ratio enhancement. Single-polarization architecture with 2.92 mm female RF interface.
