Low-Profile Wi-Fi Antenna with Reconfigurable Metasurface for FTTR Applications

This works describes a novel, low-profile, reconfigurable two-port antenna suitable for Wi-Fi in the framework of FTTR scenarios. A total of six beams can be generated by means of a Metasurface located on top of the main radiator, and including PIN diodes as reconfigurable elements., in order to ensure proper coverage across half hemisphere. The two antenna ports and their uncorrelated beams are able to manage independent data streams for improving MIMO system capabilities. Prototype testing showed that the desired coverage was achieved with a minimal number of reconfigurable elements, which makes this technology suitable for high-performance, low-cost, low-profile devices.
