The invention discloses a broadband filter antenna based on a microstrip-slot line form. The antenna comprises an input end microstrip line, a first F-shaped slot line resonator, a second F-shaped slot line resonator, a terminal open-circuit resonator, a first radiation unit, a second radiation unit, a director and a dielectric substrate; the first F-shaped slot line resonator and the second F-shaped slot line resonator are located on a metal grounding plate at a bottom layer of the dielectric substrate; a vertical arm of the first F-shaped slot line resonator and a vertical arm of the secondF-shaped slot line resonator are both parallel to the long side of the dielectric substrate; the input end microstrip line is located above the first F-shaped slot line resonator; an input port is arranged on the long side of the dielectric substrate; the terminal open-circuit resonator is located above the second F-shaped slot line resonator; and the input end microstrip line and the terminal open-circuit resonator are b
