Abstract

The present invention discloses an antenna component, an on-board radar and an automobile. The antenna component comprises: a dielectric substrate; an impedance adjustment component formed on one sideof the dielectric substrate; an array antenna formed on one side of the dielectric substrate and connected with the impedance adjustment component; a beamwidth adjustment component formed on one sideof the dielectric substrate, wherein the beamwidth adjustment component is arranged around the array antenna; and a back grounding plate formed on the other side of the dielectric substrate, whereinthe back grounding plate covers the direct below part of the impedance adjustment component, the array antenna, and the beamwidth adjustment component. According to the technical scheme of the presentinvention, the impedance adjustment component and the array antenna of the antenna component are arranged on the same side of the dielectric substrate, and the antenna component is easily adjusted toobtain a 50 ohm impedance and can be conveniently applied to a 24 GHz on-board radar without using a large-sized standard waveguide feed interface.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an antenna component, a vehicle-mounted radar with the antenna component and a vehicle with the vehicle-mounted radar. Background technique [0002] Due to the advantages of low profile and low cost, microstrip antennas are widely used in various vehicle radars. [0003] In the related technology, a microstrip comb array antenna applied in the 77GHz millimeter wave frequency band is proposed. The array antenna is mainly composed of a waveguide microstrip transition part, a comb radiation array antenna and a dielectric substrate. Among them, the waveguide microstrip transition part It is mainly composed of waveguide short-circuit surface, patch unit and WR12 standard waveguide feeding interface, and the patch unit and WR12 standard waveguide feeding interface are on the front of the dielectric substrate, and the comb radiation array antenna is on the back of the dielectric substr...
