This document describes waveguides that use a combination of air dielectric filled channels and non-air dielectric filled channels to obtain beneficial attributes of both air and dielectric waveguides. EM energy loss inside the waveguide compares to a traditional air waveguide. However, with a smaller size than a comparable air waveguide, the example waveguide can occupy less area of a chip or package than a comparable air waveguide of a traditional design. The waveguide has a routing portion with hollow channels filled with an air dielectric. Radiation channels corresponding to each of the hollow channels are loaded with a non-air dielectric. A surface of each of the radiation channels allows EM energy to escape the non-air dielectric. The described waveguide may be particularly advantageous for use in an automotive context, for example, detecting objects in a roadway in a travel path of a vehicle.

Monodirectional antennas may be arranged to radiate in a near omni-directional pattern. By incorporating switches into the antenna arrangement, the antennas can be controlled to selectively radiate from a common radiofrequency feed.

According to another aspect of the disclosure, housings may include a plurality of antennas, and one or more procedures may be implemented to determine a codebook to radiate from the circular arrangement according to various beam constrains.

In another example, an antenna array includes first and second patch antenna elements disposed on a first side of a substrate and separated by a gap; and at least one meander line (ML) slots formed in a ground plane disposed on a second side of the substrate and aligned with the gap between the first and second patch antenna elements.

An antenna array that utilizes ground guard rings and metamaterial structures is disclosed. In certain embodiments, the antenna array is constructed from a plurality of antenna unit cells, wherein each antenna unit cell is identical. The antenna unit cell comprises a top surface, that contains a patch antenna and a ground guard ring. A reactive impedance surface (RIS) layer is disposed beneath the top surface and contains the metamaterial structures. The metamaterial structures are configured to present an inductance to the patch antennas, thereby allowing the patch antennas to be smaller than would otherwise be possible. In some embodiments, the metamaterial structures comprise hollow square frames. An antenna array constructed using this antenna unit cell has less coupling than conventional antenna arrays, which results in better performance. Furthermore, this new antenna array also requires less space than conventional antenna arrays.
