Radar side-shield and a radar transceiver assembly

A side-shield for a radar transceiver, the side-shield comprising:

• a non-uniform delay structure comprising:
• a first dielectric material;
• and
• a plurality of embedded portions of at least one second dielectric material of different dielectric constant than the first dielectric material, each of the plurality of embedded portions being surrounded by, and thus physically separated by, the first dielectric material;
• the non-uniform delay structure being configured to have a radar signal propagate therethrough and to delay the radar signal propagating through the non-uniform delay structure by a variable amount in dependence of a wavelength of the radar signal and in dependence of a location on the non-uniform delay structure through which the radar signal propagates, to thereby diffuse the radar signal by phase randomization due to propagation through the non-uniform delay structure.
