Problems solved by technology
Conformal antennas can be conformed to non-planar carrier planes without affecting the carrier’s aerodynamic characteristics and other working performance, so they are widely used in platforms such as drones and missiles, as well as in fields such as communications, radar and electronic countermeasures. Existing conformal antennas are still difficult to meet the actual needs of use

Abstract
The invention relates to a conformal dual-polarized antenna based on two-way differential power divider feed. The conformal dual-polarized antenna comprises an antenna base and a radiator supporting cylinder set on the antenna base. Four radiators are printed on an outer wall of the radiator supporting cylinder. The radiators are inverse F-shaped on the radiator supporting cylinder. Two corresponding radiators on the radiator supporting cylinder form a radiation pair. The two radiators in the radiation pair is in central symmetry. Two differential power dividers are set in the antenna base. The two differential power dividers and the two radiation pairs on the radiator supporting cylinder are in one-to-one correspondence connection. Differential feed can be carried out on the connected radiation pairs through utilization of the differential power dividers, so linear polarization directions of the two radiation pairs are mutually orthogonal. The conformal dual-polarized antenna is compact in structure. Under the condition that a directional diagram and gain satisfy a communication requirement, a size can be effectively reduced, and cost and weight are reduced.
Description
technical field [0001] The invention relates to an antenna, in particular to a conformal dual-polarized antenna fed by two-way differential power dividers, and belongs to the technical field of dual-polarized antennas. Background technique [0002] Dual-polarized antennas have the characteristics of anti-multipath attenuation and increased channel capacity, and are widely used in wireless communication systems. Under some specific application conditions, there are usually strict restrictions on the size and quality of the antenna, and the shape of the antenna carrier needs to be considered. Therefore, conformal antennas have emerged, especially light-weight conformal antennas. Conformal antennas can be conformed to non-planar carrier planes without affecting the carrier’s aerodynamic characteristics and other working performance, so they are widely used in platforms such as drones and missiles, as well as in fields such as communications, radar and electronic countermeasures...
