Description

Technical Field

[0001] The invention belongs to the technical field of antennas, and in particular relates to a vehicle-mounted plate antenna. Background Art

[0002] Plate antennas are usually converters used to receive and send wireless signals. They convert guided waves propagating on transmission lines into electromagnetic waves propagating in unbounded media (usually free space), or perform the opposite conversion. A vehicle-mounted plate antenna is an antenna installed on a vehicle. It is shaped like a flat plate and is usually used in vehicle-mounted communication systems, such as vehicle-mounted satellite navigation systems and vehicle-mounted communication equipment.

[0003] For example, a reinforcement installation device for a radar antenna disclosed in Chinese patent document (CN112799021B) includes a connection panel and a radar device. The radar device includes a substrate and a radar body. The radar body is fixedly connected to the substrate below. A pressure plate is fixedly connected to the substrate below. A buffer component is arranged below the substrate. A support is arranged between the pressure plate and the connection panel. The radar device is fixedly connected to the connection panel through the pressure plate, bolts and anti-loosening nuts. In the invention, a support and a pressure plate are arranged between the radar device body and the connection panel, so that when the radar device is installed by bolts, the connection stability and connection effect between the two are improved. The connection between the two is made more secure, and the arc-shaped setting of the first support part and the second support part greatly reduces the amplitude of the vibration generated by the connecting panel and transmitted to the radar equipment through the bolts, thereby reducing the vibration impact force of the indirect radar equipment from the vehicle body and making the connection more secure.
