Abstract

This paper presents the design of a holographic metasurface-based beamforming antenna. The metasurface, built on the holographic principle, showcases its transformative ability by converting an omnidirectional monopole into a highly directional antenna. Here, we present a holographic metasurface antenna designed on top of a novel 3D-printed substrate to maintain lightweight and achieve conformality. It is meticulously tailored for optimal performance at 15 GHz with precise beam at 60° while converting the omnidirectional pattern of the monopole to directional antenna offering gain of 13 dBi using a holographic metasurface. The results of the holographic metasurface antenna are verified with cylindrical bending confirming its flexibility.
