In this contribution, we discuss the possibility to exploit functionalized metasurface coatings wrapping wired antennas for manipulating their radiation pattern. Through a proper design of a cylindrical Huygens metasurface coat, the quasi-cylindrical wavefront of the field radiated by the antenna is locally transformed into a plane wave, leading to the generation of either multiple or single radiating beams from the original omnidirectional pattern.

Finally, a realistic configuration of the device enabling reconfigurability of the antenna's radiation pattern is discussed.

Abstract

In this contribution, we discuss the possibility to exploit functionalized metasurface coatings wrapping wired antennas for manipulating their radiation pattern. Through a proper design of a cylindrical Huygens metasurface coat, the quasi-cylindrical wavefront of the field radiated by the antenna is locally transformed into a plane wave, leading to the generation of either multiple or single radiating beams from the original omnidirectional pattern. The semi-analytical model of the device is presented, and some relevant examples are provided. Finally, a realistic configuration of the device enabling reconfigurability of the antenna's radiation pattern is discussed.
