PURPOSE: A broadband patch antenna using a dipole element is provided to reduce a manufacturing cost and enhance the productivity by simplifying a structure and reducing the number of processes. CONSTITUTION: A broadband patch antenna using a dipole element includes a radiator(111a-111e), a broadband micro-strip feed line(114a,114b), a cable, and a reflector(115a-115c). The radiator(111a-111e) has a V-shaped dipole array to increase a gain of an antenna. The broadband micro-strip feed line(114a,114b) is used for distributing the predetermined power to the radiator and matching the impedance to obtain a broadband characteristic. The cable is used for supplying the power to the dipole element through the broadband micro-strip feed line. The reflector(115a-115c) is used for playing a role of the ground, directing the radiative power to the one direction, and condensing effectively the beams.
