Abstract: Millimeter wave operation in 5G base stations necessitates small cell size and advanced multi-beam capabilities. At millimeter waves, base station antennas must be highly compact, making ...

Abstract: A compact multibeam antenna is proposed with passive 2-D beam scanning capability. The antenna is composed of a Rotman lens beamformer, a slotted waveguide array (SWA), and a mechanical ...

LEO mega-constellations are expected to deploy thousands of satellites to provide broadband services with data rates approaching several Gbps and latencies as low as 30–50 ms, significantly lower than ...
