ANTENNA ANGLE ADJUSTMENT DEVICE AND AN ANTENNA
The present disclosure relates to an antenna angle adjustment device, and the angle adjustment device includes a drive member ( 10 ) and a driven member ( 4 ). The drive member is supported rotatably around a first rotation axis (X 1 ) and can be manipulated and fixed. The driven member is supported rotatably around a second rotation axis (X 2 ), and the angular position of the driven member is related to the angular position of the antenna. The drive member has an engagement point, and the driven member has a concave curved portion. The engagement point extends into the curved portion and engages the curved portion so that the rotation of the drive member around the first rotation axis can cause the rotation of the driven member around the second rotation axis. The present disclosure further relates to an antenna with the angle adjustment device. The angle of the antenna can be appropriately adjusted by the angle adjustment device.
