Abstract: Orbital angular momentum (OAM) beams present an inverted cone form and divergence. Consequently, the transmission distance and rate of the backhaul link based on OAM are severely limited. On ...

Abstract: In this paper, the influence of reflected wave on the radiation performance of holographic antenna is analyzed, and a double-beam holographic antenna is designed. The proposed antenna etches ...

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 ...
