PURPOSE: A reverse-F antenna using a branch capacitor is provided to maintain a primary resonance frequency and form a resonance frequency in other band. CONSTITUTION: A reverse-F antenna includes a radiator(200), a ground surface(202), a ground pin(204), a power supplying pin(206), a first branch arm(208), a second branch arm(209), a branch capacitor(210). The radiator implements the radiation function of a supplied radio-frequency signal and the reception function of the radio-frequency signal. The ground surface and the radiator are connected by the branch capacitor. Another branch path is formed by the branch capacitor.
