A 4-port stacked-patch microstrip antenna is used as feeder of a perforated flat lens. Each feeder is placed in a different position with respect to the lens, yielding four high-directivity independent beams. The beams cover an angular range from broadside to a 30-degree steering with a gain over 18 dB. The antenna has been implemented by low-cost processes, employing Printed Circuit Board fabrication for the feeder and 3D printing for the lens.}, keywords = {5G mobile communication, Beam steering, Microstrip antennas}, doi = {10.23919/EuCAP48036.2020.9135364}, author = {E Garcia-Marin and D S Filipovic and J L Masa-Campos and P Sanchez-Olivares} }
