A large imaging array in Ka band with a substrate integrated waveguide Pillbox beamformer

Abstract

A novel multiple beam antenna is proposed in Ka band. It consists of a dual reflector imaging configuration magnifying a reconfigurable phased array of smaller size, that produce a 2D coverage of multiple spot beams with a quasioptical beamformer made of ¨Pillbox 1D beamformers.

Glide-Symmetric Fully Metallic Luneburg Lens for 5G Communications at K<roman>a</roman>-Band

“…The measurements demonstrate a stable gain with respect to the angle of scanning. A higher level of overlapping between beams could be achieved by placing the feedings closer to each other, although this would lead to an increase in the coupling between ports [44], [45]. V. CONCLUSION Here, we have proposed a fully-metallic Luneburg lens for 5G communications at the Ka-band.…”
