Abstract
Embodiments provide a radio frequency apparatus including a radome, an absorber, and a radio frequency circuit board that may be used for millimeter wave radar of an intelligent automobile to reduce high-frequency radiation interference from a radio frequency chip and an antenna feeder.
Claims20
A radio frequency apparatus, comprising:
- a radome;
- an absorber comprising a top surface, one or more supporting pieces, and one or more securing pieces;
- and
- a radio frequency (RF) circuit board comprising at least one RF chip, at least one antenna feeder, and at least one RF antenna array, wherein the at least one antenna feeder connects the at least one RF chip to the at least one radio frequency antenna;
- the radome being configured to accommodate the RF circuit board, the top surface of the absorber covering the at least one RF chip and covering the at least one antenna feeder so as to electromagnetically shield the at least one RF chip and the at least one antenna feeder, the at least one RF antenna array arranged beyond the top surface of the absorber so as to be uncovered and electromagnetically unshielded by the top surface of the absorber, the at least one RF antenna array being electromagnetically shielded from interference from the at least one RF chip and the at least one antenna feeder, and the one or more securing pieces being configured to secure the absorber to the RF circuit board and to position the top surface of the absorber between the radome and the RF circuit board.
