Abstract

Automotive radars are often required to be placed behind a car bumper. The bumper layers can produce significant degradation to the radar antenna gain and hence to the maximum detectable range of the radar. It is shown that by adding a dielectric matching layer or/and by tilting the bumper with respect to the antennas, it is possible to reduce the gain degradation across the radar field of view. The idea is illustrated via a concrete example of a printed patch antenna located behind a bumper sample taken from a car. Good agreement is demonstrated between simulations and measurements.
