Abstract
Antenna assemblies, such as RADAR sensor antenna assemblies, that incorporate destructive interference elements. In some embodiments, the assembly may comprise one or more waveguides, one or more antenna slots, and a plurality of destructive interference elements. The destructive interference elements may be configured to reduce backscatter radiation by contributing to destructive interference of electromagnetic waves incident upon the destructive interference elements. In some embodiments, the destructive interference elements may be defined and/or exposed by a plate that may be coupled with a waveguide block or another layer/component of the assembly.
