Radio frequency antenna orientation adjusting device

The invention provides a radio frequency antenna orientation adjusting device which comprises a rectangular coordinate motion device which is used as a carrier for installing a polar coordinate motion device; the middle part of the polar coordinate movement device is mounted to the middle part of the rectangular coordinate movement device; and one end of the spherical coordinate movement device is mounted at one end of the polar coordinate movement device. The radio frequency antenna has the beneficial effects that the degrees of freedom of motion are designed in a series-connection structural form, and the degrees of freedom independently move and do not interfere with each other, so that the radio frequency antenna can be conveniently adjusted through the combination of different degrees of freedom of motion when the position posture is adjusted, and the radio frequency antenna has the same position posture, so that the adjustment precision is improved. According to the invention, a plurality of combination
