Title:
LARGE-BANDWIDTH COPLANAR FEED ANTENNA DESIGNED FOR A MILLIMETER-WAVE RADAR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/199020
Kind Code:
A1
Abstract:
The present invention relates to a coplanar feed antenna, comprising: a lower layer base plate, a middle layer base plate, and an upper layer base plate disposed in sequence; an antenna (101); and a feed structure. The antenna (101) is located on the upper layer base plate. The feed structure comprises a feed portion (201) and a feed conversion portion (301). The feed portion (201) is located on the upper layer base plate. The feed conversion portion (301) comprises a conversion region located on the upper layer base plate, the middle layer base plate, and the lower layer base plate. The communication between antenna signals and the feed portion is realized by means of the feed conversion portion (301). The antenna is characterized by a wide working bandwidth, high sidelobe suppression at a pitch plane, improved radiation gain flatness, and stable beam pointing.
