Abstract
A self-filtering, space-time coding, waveguide-driven metasurface antenna includes at least first and second metal layers, and first dielectric layer between the first and second metal layers. A series of vias is formed in the first dielectric layer. A substrate integrated waveguide (SIW) is formed from the first and second metal layers and from the metal vias in the first dielectric layer. A series of meta-atoms is formed in the first metal layer, each meta-atom including a slot cooperating with two switching elements for switching the meta-atom between an on and off state. Each meta-atom behaves as a magnetic dipole antenna element that radiates electromagnetic waves into free space. In this manner, the propagating guided waves inside the substrate integrated waveguide are converted and molded into arbitrary selected out-of-plane free-space waves in both a frequency domain and a momentum domain.
