Coplanar waveguide dual-polarized notch cross dipole antenna with three radiation zero points

The invention relates to a three-radiation-zero-point coplanar waveguide dual-polarization notch cross dipole antenna which comprises a dielectric substrate, a metal reflecting plate and two coaxial cables, the cross dipole antenna is printed on the upper layer and the lower layer of the substrate and is fed by the two coaxial cables, and the metal reflecting plate is located below the dielectric substrate. The broadband dual-polarization cross dipole antenna covering 1.7-3.6 GHz is firstly designed by using a coplanar waveguide feed structure, then the coplanar waveguide DMS-DGS hybrid three-order band elimination filter is designed, and the miniaturized high-selectivity coplanar waveguide filter and the antenna are printed on the same dielectric substrate, so that a stop band covering 2.9-3.1 GHz is realized. At VSWRlt; under the conditions of 1, 2, compared with an original broadband antenna covering the frequency band of 1.7-3.6 GHz, the notch antenna provided by the invention works in two working frequen
