Implementation and Far-Field Calibration of an 8×8 37-40 GHz Phased Array with Vivaldi Aperture
Paper in proceeding, 2022
A 64 element phased array is implemented using an all metal Vivaldi aperture and 16 commercial beamforming ICs integrated on a 10-layer RF -PCB. The interconnects within the PCB are designed using circular barrels to avoid unwanted resonances, as is demonstrated by full wave simulation. The use of a non-isolated power combiner in receive mode is validated by comparing two far-field calibration techniques, resulting in measured high-fidelity beams steering up to 50°.
