Description
Summary:	We present in this paper a flat panel dual slant linear polarized (±45 ° ) transmit and receive (TIR) phased array antenna (PAA), that operates in the Ka-Band, which covers the millimeter-wave 5G band (27.5 - 28.35 GHz). The developed beamforming array utilizes commercially available silicon radio frequency integrated circuit (RFIC) beamforming chipsets. The PAA operates from 26 - 30 GHz and features both 6-bit phase and amplitude control. Simulation is compared to measurement results. We demonstrate beam scanning up to ±55 ° in both polarizations. We also show ability to form sum and difference beam patterns utilizing amplitude weighting for monpulse tracking. The size of the array board is 102 mm x86 mm x4 mm.
