Document Type and Number:
WIPO Patent Application WO/2023/024902
Kind Code:
A1
Abstract:
Disclosed in the present invention are a vehicle-mounted millimeter-wave radar, and a transmitting antenna system, a receiving antenna system and an antenna system therefor. The transmitting antenna system comprises: a millimeter-wave radar monolithic microwave integrated circuit comprising at least one transmitting channel, at least one transmitting antenna group, at least one power division network, and at least one orthogonal coupler, wherein one transmitting channel, one power division network, one orthogonal coupler, and one group of transmitting antennas are sequentially connected to form an electromagnetic signal transmitting link; the millimeter-wave radar monolithic microwave integrated circuit transmits an electromagnetic signal to the power division network through the transmission channel; the power division network divides the electromagnetic signal into two transmission signals and then transmits the two transmission signals to the orthogonal coupler; and the orthogonal coupler couples the two transmission signals and then divides the coupled transmission signal into two coupled transmission signals, and transmits the two coupled transmission signals to a first polarized antenna and a second polarized antenna of the transmitting antenna group. By means of embodiments of the present invention, the antenna system can adapt to different operating environments, thereby improving the co-frequency anti-interference level of the system.
