Title:
ANTENNA
Document Type and Number:
WIPO Patent Application WO/2023/142241
Kind Code:
A1
Abstract:
The present invention relates to the field of millimeter wave detection, and particularly relates to an antenna with a bidirectional radiation capability. The antenna comprises an end-fire antenna and a side-fire antenna, wherein the end-fire antenna and the side-fire antenna are disposed on the same PCB, and an included angle between the main polarization direction of the end-fire antenna and the main polarization direction of the side-fire antenna is 80-100 degrees. In the present invention, by means disposing both an end-fire antenna and a side-fire antenna on one PCB, simultaneous transmission and reception in two directions is achieved, such that a PCB and a control system are saved on, and the manufacturing cost of a millimeter-wave radar system which is capable of achieving bidirectional detection, especially bidirectional detection in orthogonal directions, is greatly reduced.
