Traces between phase array antenna and radio frequency integrated circuit in mm wave systems

Abstract:

Systems and associated methods for improved beamforming of the phase array antenna are disclosed herein. In one embodiment, a communication system for wireless signals has a phase array antenna having a plurality of individual antennas and a plurality of electrically conductive traces. The individual traces electrically connect corresponding individual antennas with a transmitter. The lengths of individual traces Ti, Tk satisfy equation Abs((Ti-Tk)mod(.lamda.))<.lamda./B, where .lamda. is a wavelength of the wireless signal and .lamda./B is a fraction of .lamda.. A beamformer performs amplitude and/or phase adjustment to the wireless signal to be applied to each individual trace, wherein the beamformer operates to cancel phase offsets generated by unequal trace lengths.
