To realize a reflector-provided dipole antenna showing an outstanding performance in a wide frequency range and allowing simultaneous transmission and reception at different frequencies. A dipole antenna element is provided at the back of a dielectric substrate set to the reflector surface. A parasitic element is provided on the front of the dielectric substrate, which is constituted by forming and protruding the central portion of a linear conductor forward like an almost trapezoidal shape, setting the pyramidal protruded portion to a position corresponding to the front of the feed point of the dipole antenna element and the both parts of the said parasitic element towards ends to positions corresponding to the rear of the dipole antenna element. A feed circuit provided on the face side of dielectric substrate is connected to a coaxial connector provided at the back of the reflector.
