Title:
ANTENNA, DETECTION APPARATUS, RADAR AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2022/160974
Kind Code:
A1
Abstract:
An antenna, a detection apparatus, a radar and a terminal. The antenna comprises a first dielectric substrate, a feed line, a plurality of coupling patches and a plurality of parasitic patches, wherein the feed line and the coupling patches are located on one side of the first dielectric substrate, the coupling patches are sequentially arranged in the extension direction of the feed line, and there is a gap between at least one coupling patch and the feed line; the plurality of parasitic patches are located on the side of the first dielectric substrate that is away from the feed line, and at least one of the plurality of parasitic patches corresponds to at least one coupling patch; and the orthographic projection of a parasitic patch among the at least one parasitic patch on the first dielectric substrate at least partially overlaps with the orthographic projection of a gap between the coupling patch corresponding to the parasitic patch and the feed line on the first dielectric substrate. Therefore, coupled feeding between a coupling patch and a feed line is realized in a gap coupling manner, and a parasitic patch is excited by a coupling gap, such that the coupling patch and the parasitic patch are excited at the same time to realize different resonant frequencies, thereby widening the operating bandwidth, and realizing the broadband characteristic.
