Waveguide assemblies are described that utilize a surface-mount waveguide for vertical transitions of a printed circuit board (PCB). The surface-mount waveguide enables low transmission-loss (e.g., increased return-loss bandwidth) by utilizing a waveguide cavity positioned over a plated slot to efficiently transfer electromagnetic energy from one side of the PCB to another side. The waveguide cavity is designed to excite two resonant peaks of the EM energy to reduce a return-loss of power and increase power delivered to an antenna while supporting a high bandwidth of EM energy. Furthermore, the surface-mount waveguide does not require precise fabrication often required for vertical transitions, allowing the surface-mount waveguide to be compatible with low-cost PCB materials (e.g., hybrid PCB stack-ups).

A radar system comprises a radar device defining upper and lower pairs of mounting tabs and being configured to transmit and receive electromagnetic waves based on a squint angle, a mounting device configured to be attached to a surface and to receive the radar device, wherein the mounting device defines upper and lower pairs of connection position assurance (CPA) features that correspond to the upper and lower pairs of mounting tabs, and a pair of mounting tab caps configured to be selectively installed on the upper or lower pairs of mounting tabs to offset the squint angle of the radar device.
