A radar system and method with reduced multipath effects include a first component of a radar sensor module on which at least one antenna element is formed, the at least one antenna element having a surface at which radar radiation is received or transmitted, the at least one antenna element having a radiation aperture. A second component in proximity to the antenna element such that a portion of the radar radiation impinges on the second component comprises an angled surface forming an angle with the surface of the antenna element. The angled surface of the second component comprises a texture such that when the portion of the radiation impinges on the angled surface, the amount of multipath signal propagating through the radiation aperture of the antenna element is reduced.

Apparatus and method for mitigating multipath effects and improving absorption of an automotive radar module

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.

Compact shielded automotive radar module and method

A housing for a radar sensor module has a back surface and a plurality of side surfaces connected to the back surface. A vent structure is connected to the back surface and at least one of the side surfaces. The vent structure includes an enclosure enclosing a chamber. A first opening in the vent structure penetrates the at least one of the side surfaces of the housing, such that the chamber is exposed to an exterior of the housing. A second opening in the vent structure penetrates the enclosure such that the chamber is exposed to an interior of the housing.

Automotive radar system and automotive radar sensor module with breather structure

An electronic module and method of making an electronic module include a printed circuit board (PCB) having a surface, at least one conductive trace being formed on the surface. A housing element for mechanically mating with the PCB includes at least one mating surface aligned with the conductive trace on the PCB when the PCB and the housing element are mechanically mated, the mating surface comprising a plurality of alternating protrusions and spaces between the protrusions. An electrical gasket is formed on the mating surface of the housing element such that the electrical gasket conforms with the protrusions and spaces on the mating surface of the housing element and is disposed between the mating surface of the housing element and the conductive trace on the surface of the PCB when the housing element and the PCB are mechanically mated, such that the electrical gasket provides an electromagnetic interference (EMI) seal between the mating surface of the housing element and the conductive trace on the first surface of the PCB.
