Fully integrated miniaturized radar sensor in LTCC multilayer technology with planar dual antenna device

摘要

Fully integrated miniaturized RADAR sensor for short-range monitoring (Short Range RADAR, SRR) of neighboring objects in the environment, in particular for determining the distance, location, speed and properties such as size, nature and material of detected objects - the RADAR sensor according to the FMCW (frequency-modulated continuous-wave) RADAR method is operated and - the RADAR sensor requires only a single antenna device for operation and - the entire high-frequency part of the RADAR sensor together with the antenna device required for operation is completely in LTCC ( Low temperature co-fired ceramic) multi-layer technology is implemented as a monoblock and - wherein the LTCC monoblock has a top and a bottom and - wherein the entire high-frequency circuit of the RADAR sensor with the hybrid microwave components (6) is on the bottom, characterized that - a resonant slot line antenna (9), which is directly coupled to a microwave electronic circuit, is used as the primary radiator, - with the shielding arranged in a LTCC monoblock arranged within the LTCC monoblock to form the radiation lobes.
