Preferably, the outer surface of the contact is gold plated.
Furthermore, the transmission body is a hollow cylinder with one end sealed, the outer surface of the transmission body is plated with silver, and the contact element is welded with one end of the transmission body sealed; the hollow cylinder of the transmission body is arranged, so that the weight of the cross dipole antenna is further reduced, and meanwhile, the use of materials is saved.
Preferably, a matching shaft extends outwards from one end face of the transmission body seal along the axis direction of the transmission body seal, and a matching hole corresponding to the matching shaft is formed in one end of the contact element; the shearing resistance of the welding position of the inner conductor of the cross dipole antenna is improved, the stability of the inner conductor of the cross dipole antenna is improved, and the electric conductivity is guaranteed.
Preferably, a soldering tin hole is formed in the contact piece along one radial direction of the matching hole, the soldering tin hole is communicated with the matching hole, and an annular soldering tin groove corresponding to the soldering tin hole is formed in the matching shaft; the connection strength of the contact element and the transmission body is further improved, the transmission body matching shaft is prevented from loosening in the contact element matching hole to influence the signal transmission performance of the crossed dipole antenna, and the stable feeding is ensured.
Preferably, one end of the contact piece, which is far away from the transmission body, is provided with a jack or a contact pin which is matched with the connector; and corresponding jacks or pins are arranged according to the connecting ends of the connectors.
The invention has the following advantages and beneficial effects:
the density of the transmission body material is lower than that of the contact element material, the overall weight of the crossed dipole antenna is reduced, the equipment operation cost is reduced, particularly for equipment with strict weight indexes in the satellite class, and the satellite emission cost and the operation cost are greatly reduced.
