Abstract
An automobile radar module and method include a PCB having a first side on which RF electronic components are mounted and a second side on which digital electronic components are mounted. An EMI shield is mounted over the first side of the PCB, and a radome is mounted over the EMI shield. The EMI shield comprises an aperture exposing RF components on the first side of the PCB. The radome comprises a protrusion which protrudes into the aperture in the EMI shield. The protrusion and sidewalls of the aperture define a shielded region above the RF components on the first side of the PCB. The sidewalls extend at an acute angle with respect to a plane of the primary surface of the EMI shield, the acute angle being selected based on operational parameters of the radar module such that a predetermined shielding performance is realized.
