Beam Squint in Ultra-wideband mmWave Systems: RF Lens Array vs. Phase-Shifter-Based Array
Sang-Hyun Park, Byoungnam Kim, Dong Ku Kim +3
In this article, we discuss the potential of radio frequency (RF) lens for ultra-wideband millimeter-wave (mmWave) systems. In terms of the beam squint, we compare the proposed RF…
RF Lens Antenna Array-Based One-Shot Coarse Pointing for Hybrid RF/FSO Communications
Hyung-Joo Moon, Hong-Bae Jeon, Chan-Byoung Chae
Because of its high directivity, free-space optical (FSO) communication offers a number of advantages. It can, however, give rise to major system difficulties concerning alignment…
An Energy-efficient Aerial Backhaul System with Reconfigurable Intelligent Surface
Hong-Bae Jeon, Sung-Ho Park, Jaedon Park +2
In this paper, we propose a novel wireless architecture, mounted on a high-altitude aerial platform, which is enabled by reconfigurable intelligent surface (RIS). By installing RIS…
