The Antenna Dome Real-Time Distributed Antenna Pattern Characterization System

In this contribution we present the hardware components, system architecture and software modules constituting the base of the TU Delft high speed Antenna Dome. The modular architecture together with the custom designed detecting unit cell allows for real-time 2D antenna characterization, providing user defined performance, optimized for the 5G FR2 mm-wave band. The various high frequency components (i.e., antenna, square-law detector) and logical subsystem composing the dual-polarization signal acquisition unit are described and evaluated for their performance. The routines and algorithm allowing for accurate 2D spatial interpolation and the system calibration/normalization are reviewed. Finally, preliminary measurement data of antennas operating in the FR2 band are presented.
