Compact Shielded Automotive Radar Module and Method |
| 摘要 |
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. |

1. An automobile radar module, comprising:
a housing; a printed circuit board (PCB) mounted in the housing, the PCB having a first side on which radio frequency (RF) electronic components are mounted and a second side on which digital electronic components are mounted; an electromagnetic interference (EMI) shield mounted over the first side of the PCB; and a radome mounted over the EMI shield; wherein: the EMI shield comprises at least one aperture through a primary surface of the EMI shield, the at least one aperture exposing at least a portion of the RF components on the first side of the PCB; the radome comprises at least one protrusion Which protrudes into the at least one aperture in the EMI shield; the at least one protrusion on the radome and sidewalls of the at least one aperture on the EMI shield define a shielded region above the portion of the RF components on the first side of the PCB; and the sidewalls of the at least one aperture 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 desired shielding performance is realized. |
