  • Patent number: 10819042
    Abstract: A broadband low-profile dual-linearly polarized antenna for a OneLTE two-in-one platform and an antenna array device formed therefrom are provided that can realize low-profile and ultra-broadband and have such advantages as simple structure, neat appearance, easy engineering implementation, and suitability for mass production. The broadband low-profile dual-linearly polarized antenna can include (1) a radiating portion that can include a dielectric substrate, printed folded dipoles spaced apart on an upper surface of the dielectric substrate, first coupled parasitic elements on a lower surface of the dielectric substrate, and second coupled parasitic elements on the upper surface of the dielectric substrate and (2) a feed balun for feeding the radiating portion, wherein each of the printed folded dipoles can include a corresponding one of the first coupled parasitic elements and a corresponding one of the second coupled parasitic elements.
