5G BEAMFORMING ANTENNA OVER A WIDE-BAND MINIATURIZED BY SEGMENTING THE SUBSTRATE-INTEGRATED-WAVEGUIDE STRUCTURE INTO LAYERS AND STACKING THEM

摘要

After separating the substrate integrated structure according to an embodiment of the present invention into segments as element functions, the area reduction beamforming antenna for 5G small terminals and repeaters by a zigzag stacking technique has a frequency from 26.5GHz to 28.9GHz planned for 5G communication service. This is a broadband beamforming antenna that includes all of the bands, and the overall size of the antenna is greatly reduced by applying an unprecedented folded structure in which layers are stacked (zigzag) back and forth between the input port and the output port, not in the direction of signal flow. We present a structured beamforming antenna.
