Abstract :
A passive technique is developed in this paper to achieve UWB beamforming using a 1 × N device able to code the waves received and transmitted by an antenna array, preventing the use of phase shifters, delay lines, or moving parts. The link between the array inter-element space and the beamforming performance is studied to show the possible application of this device for far-field high resolution beamforming, achieved in a passive way.
