The invention relates to a probe antenna and a probe thereof, the probe antenna comprises two radiation units which are arranged in a mutually orthogonal manner, and each radiation unit comprises a substrate, two radiation surfaces located at two sides of the substrate and a feeder line arranged in the substrate. The radiating surface comprises a first conductive area, a second conductive area and a non-conductive area located between the first conductive area and the second conductive area, the width of the non-conductive area is gradually increased in the first direction, the feeder line comprises a coupled feeder line section, and the coupled feeder line section is located below the non-conductive area. As the two radiation units are consistent and orthogonally arranged, the problem that the same polarization directional diagram of the probe antenna is asymmetric is solved, the consistency of the directional diagram of the main polarization is poor, and the influence of cross polarization on the main polar
