摘要：
This contribution presents preliminary results of a reflectarray antenna to generate a multi-spot coverage from a LEO satellite for 5G and Beyond-5G communications. The reflectarray is proposed to generate the complete multi-spot coverage at 18.2 GHz for the user's downlinks The phase distributions on the reflectarray surface have been optimized to broaden the beams at the same time as reducing the distortion of the beams at the edge of the coverage. The antenna performance of a standard reflectarray (with a conventional phase distribution to focus pencil beams) and the proposed reflectarray have been compared by simulated results. The simulations show that the proposed reflectarray can generate a continuous coverage of 36 beams with an End-Of-Coverage level of 26 dBi.
