摘要： A cavity slotted-waveguide antenna array has several waveguide columns disposed in parallel in a housing. Several of the waveguide columns being provided with cavity slots on the front side of the housing. The housing includes a front part secured to a rear part, with a rear portion of the waveguide columns being formed in the rear part, and with a front portion of the waveguide columns being formed in said front part. The waveguide columns can have a rectangular cross-section, with the columns defined by two opposing wide inner surfaces, a narrow inner back surface, and a narrow inner front surface, with the plurality of cavity slots extending from the front side of the housing to said narrow inner front surface. A signal probe is disposed in the columns. Conductive parallel plate blinds are conductively secured to the front side of the housing.

摘要： An Improved Roadway Guidance System provides guidance elements in a roadway as means to guide a vehicle along the roadway, as well as supply important information to the vehicle to enhance the autonomous operation of the vehicle in a safe and efficient manner. The system comprises at least three parts: (1) the use of overlaid roadway “emitter strips” that provide an extended excitation/emission field simultaneous with direct guidance instructions to passing vehicles; (2) the use of a linearly-arranged antenna array system provided on the vehicle and adapted for interaction with the emitter strips for positionally locating the vehicle within a travel lane and providing additional informative data for operation of the vehicle; and (3) the use of a multi-port Receiver Unit that works with the antenna array and the host vehicle's guidance system to optimize autonomous operation of the vehicle.

摘要： This document describes a single-layer air waveguide antenna integrated on a circuit board. The waveguide guides electromagnetic energy through channels filled with air. It is formed from a single layer of material, such as a sheet of metal, metal-coated plastic, or other material with conductive surfaces that is attached to a circuit board. A portion of a surface of the circuit board is configured as a floor of the channels filled with air. This floor is an electrical interface between the circuit board and the channels filled with air. The single layer of material is positioned atop this electrical interface to define walls and a ceiling of the channels filled with air. The single layer of material can be secured to the circuit board in various ways. The cost of integrating an air waveguide antenna on to a circuit board this way may be less expensive than other waveguide-manufacturing techniques.
