Abstract
An all-metal dual-polarized feeding element and an all-metal dual-polarized panel antenna are provided. According to the present disclosure, a first metal plate and M*N same waveguide radiating ports on the first metal plate form a radiating network. A second metal plate, a third metal plate, a fourth metal plate, a quadruple-ridged waveguide array, a first polarization feeding network, a second polarization feeding network, a coaxial to double-ridged waveguide array, and a double-ridged waveguide to quadruple-ridged waveguide array form a feeding network. Therefore, the dual-polarized feeding element and the dual-polarized panel antenna realize a wide bandwidth, a high efficiency and a low profile. The present disclosure solves problems of poor performance and hard realization of existing dual-polarized antennas in wide bandwidth, high efficiency and low profile.
