Abstract
An antenna system includes a printed circuit board (PCB) on which electronic components are mounted and an antenna module mounted on the PCB. A coupling element on the PCB couples the antenna module to at least one of the electronic components. The antenna module comprises a radio-frequency (RF)-compatible antenna substrate and an antenna structure plurality of antenna patches formed on the RF-compatible antenna substrate.
Claims8
An automotive radar antenna system, comprising:
- a printed circuit board (PCB) on which electronic components are mounted, the PCB being made of a first material;
- an automotive radar antenna module mounted on the PCB, wherein the automotive radar antenna module comprises a radio-frequency (RF)-compatible antenna substrate made of a second material different from the first material, and an automotive radar antenna structure comprising a plurality of antenna patches formed on the RF-compatible antenna substrate;
- a mounting structure for mounting the antenna module on the PCB, the mounting structure including a ball grid array (BGA) formed on a bottom surface of the antenna substrate;
- and
- a coupling element on the PCB coupling the antenna module to at least one of the electronic components, the coupling element comprising an antenna feeding structure, the antenna feeding structure comprising a microstrip-to-waveguide transition.
