The flexible paraboloid satellite-borne antenna comprises four cross ribs, ten air-inflated supporting pipes and a flexible reflection surface. The four cross ribs are arranged in parallel to form a trapezoid. The two ends of each air-inflated supporting pipe are closed, the two ends of the four cross ribs are connected with the ten air-inflated supporting pipes through tee joints, every two adjacent air-inflated supporting pipes are connected through a connecting pipe arranged in the corresponding tee joint, and two air inflation holes in each cross rib are communicated with the air-inflated supporting pipes at the two ends of the cross rib respectively through one corresponding connecting pipe. The two ends of the flexible reflection surface are connected with the cross rib 1A and the cross rib 1D respectively. The flexible paraboloid satellite-borne antenna is used for satellite-borne wireless signal receiving and sending.
