Fast Multibeam Training for mmWave MIMO Systems With Subconnected Hybrid Beamforming Architecture
IEEE Systems Journal, 2023In this article, we present novel multibeam training strategies for millimeter-wave communication systems with the subconnected hybrid architecture. To begin with, we propose an iterative selecting search (ISS) algorithm that can reduce the training ...

Steerable Simultaneous Multibeam Antenna Based on Reconfigurable Reflectarray
IEEE Antennas and Wireless Propagation Letters, 2023Multibeam system is a core part for wireless concurrent communication and massive multiple-input–mulitple-output (MIMO) applications. Traditional concurrent communication techniques, like phased-array or digital beam-forming system, suffer from massive ...

Millimeter-Wave Dual-Polarized Multibeam Endfire Antenna Array With a Small Ground Clearance
IEEE Transactions on Antennas and Propagation, 2022A dual-polarized multibeam endfire antenna array is presented for 5G millimeter-wave applications. The antenna element employs double-layer stack-up substrate integrated waveguides (SIWs) and stepped slot to serve as a polarizer. Dual-linear polarization

Multibeam Antenna in Millimeter Waves
32nd European Microwave Conference, 2002, 2002This paper deals with a multibeam antenna in 60 GHz band. This structure is based on a Butler Matrix which fed a four printed antenna array. Two different solutions are presented to avoid the crossing point of the microstrip line : a microstrip-thick slot-microstrip transition or two hybrids 90°.
