Foldable vehicle-mounted satellite antenna

The invention relates to a foldable vehicle-mounted satellite antenna. The antenna comprises a fixing support, a reflecting surface and a receiver support. The receiver support comprises a telescopic rod, and one end of the telescopic rod is connected with the middle of one side of the fixing support in a rotating mode. The reflecting surface comprises two sets of folding surfaces symmetrically arranged on the two sides of the receiver support, and the folding surfaces comprise a folding plate A and a folding plate B connected with the folding plate A through a hinge in a rotating mode. The folding plate A is further is connected with the other end of the fixing support in a rotating mode. The signal reflecting surface is composed of the two folding surfaces allowing folding, the folding degree is high, in the folding process, the whole antenna is in a thin plate shape, wind resistance is low, and because the foldable antenna is a pot-like antenna, the signal receiving capacity is high.
