[0030] Such as figure 1 As shown, a low-profile dual-polarized filter magnetoelectric dipole antenna includes an upper dielectric substrate and a lower dielectric substrate separated by a certain distance between two layers, the upper surface of the upper dielectric substrate is printed with a radiator structure, and the lower dielectric substrate Substrate printed slot-coupled feed network structure, using the slot-coupled feed network with fusion filtering function to excite the radiator structure with low profile and high selective filter response, resulting in good broadband radiation characteristics and high roll-off band-pass filter effect.
[0031] Such as figure 2 As shown, the radiator structure includes four parasitic patches 3 loaded with symmetrical slits 1 and short-circuit probes 2, and the four parasitic patches form a rectangular structure. The symmetrical slits in this embodiment are placed on each parasitic On the patch, there are two symmetrical gaps about...
