Metasurface Antennas Radiating Quasi-Bessel Beams for Near-Field Applications
In this work, we present two distinct metasurface antenna designs operating at 30 GHz, aimed at generating quasi-Bessel beams with non-diffractive ranges reaching up to several hundred wavelengths. The first antenna is a meta-axicon transmitter, consisting of a horn antenna coupled with a 3D-printed dielectric metasurface. The second design involves a printed metasurface launcher, excited by a coaxial pin. Numerical simulations of both configurations demonstrate highly efficient beam generation and maintain beam integrity over distances exceeding hundreds of wavelengths.
