Low Profile Wideband Scanning Antenna in Ka-band Based on Fully Metallic Metasurfaces

Résumé

In this paper, a high gain antenna based on low profile metasurfaces is designed and numerically analyzed. The operation principle is the same of series fed Continuous Transverse Stub (CTS) structures, but in comparison to prior designs, radiation efficiency and compactness are improved by feeding the radiating aperture with a planar lens working in reflection. The lens can be realized using a pin-type metasurface, resulting in a fully metallic construction. The radiating aperture is realized by etching slots in the upper wall of a parallel plate waveguide loaded with corrugations; this solution provides an almost frequency- and scan-independent active impedance, resulting in wideband performance for all the pointing directions. Furthermore, because of the axial symmetry of the feeding structure, the antenna has the capability of generating multiple beams from the same aperture while maintaining excellent port decoupling.
