 Metasurface antennas offer a unique solution to the need for high-performance low-profile transceivers in 5G per 6G networks and broadband satellite internet access. These antennas are based on the principles of quasi-bound states in the continuum, which allow for full control over the amplitude, phase and polarization of the aperture field. This allows for a wide range of functionality, such as single input multiple output, MIMO, near-field focusing, as well as far-field beam shaping. Metasurface antennas have been demonstrated experimentally and are expected to be used in future wireless communication systems.
