Antenna Pattern Shaping through Functionalized Metasurface Coatings

In this contribution, we discuss the possibility to exploit functionalized metasurface coats wrapping wired antennas for manipulating their radiation pattern. Through a proper design of the Huygens metasurface coating, the quasi-cylindrical wave front of the field radiated by the antenna is locally transformed into a plane wave, leading to the generation of 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.
