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 (λ))
