PURPOSE: A dual-resonance broadband antenna for an intelligent traffic system service is provided to transceive frequencies in the range of 5.7GHz to 6.2GHz and 2GHz to 3GHz. CONSTITUTION: A dual-resonance broadband antenna for an intelligent traffic system service comprises the following devices. A conductive pattern is formed on a dielectric substrate(5). A first conductive pattern is formed on the central part of the dielectric substrate. A second conductive pattern is formed on the first conductive pattern. A third conductive pattern is formed on the central part of the other side of the dielectric substrate. A fourth conductive pattern is formed on the third conductive pattern. A housing(60) surrounds the dielectric substrate.
