US 2022/0179039 A1 · Facia Supporting an Ultra-Wide Radar Field-of-View

Abstract

This document describes facia, including parts of vehicles, for supporting an ultra-wide radar field-of-view, for example, in automotive contexts. The facia is configured as a radome for supporting an ultra-wide field-of-view with an antenna despite the facia obstructing a field of view. The facia has one exterior surface or interior surface this is a mostly smooth or has a pattern of hemispherical indentations or domes that are configured to reduce reflections off that surface and increase light transmission through the facia. The other of the exterior or interior surface, has a pattern of hemispherical indentations or domes that are configured to reduce reflections off that surface and further increase light transmission through the facia.

Claims20

Dependent claims

A system comprising:

an antenna including an array of elements directed towards a field-of-view;
and
a facia for a vehicle and configured to be arranged between the antenna and the field-of-view, the facia having an exterior surface exposed to the field-of-view and an interior surface that is opposite the exterior surface and exposed to the array of elements,
the facia is configured as a radome having on at least one of the interior surface or the exterior surface a respective pattern of hemispherical indentations or domes that are configured to trap light, the trapping of the light being effective to reduce reflections off that surface and increase light transmission through the facia to support an ultra-wide field-of-view using the antenna despite the facia obstructing the field of view.
