摘要： In some examples, a method for generating a set of slot activation configurations for a holographic radial line slot antenna array comprising multiple slots defining a preconfigured slot pattern, each slot activation configuration defining a beam pattern for a signal to be emitted by the antenna, comprises generating a measure for the mutual coupling between the multiple slots in the presence of a signal to be applied to the antenna, the measure comprising a set of scattering parameters defining a scattering matrix for the antenna, using the measure for the mutual coupling, generating a set of impedance parameters for the array, controlling the resonance of at least one of the multiple slots by regulating a value of capacitance of a variable capacitance device provided across the slot, measuring a value for antenna gain of a beam pattern associated with the value of capacitance, selecting a final value of capacitance resulting in the highest measure of gain for the beam pattern, and selecting a slot activation configuration for the beam pattern on the basis of the selected final value of capacitance.

摘要： Antenna structures and assemblies for use in RADAR sensor assemblies and the like. In some embodiments, the assembly may comprise a feed waveguide comprising one or more feeding slots and a parallel plate waveguide operably coupled with the feed waveguide such that each of the one or more feeding slots of the feed waveguide is configured to inject electromagnetic energy into the parallel plate waveguide. A plurality of radiating slots may be formed in a plurality of rows and/or columns extending away from the feed waveguide to deliver electromagnetic energy out of the antenna assembly.
