Abstract
An antenna structure includes a substrate, a radiation unit, and a metal plate. The radiation unit is disposed on the substrate. The metal plate is separated from the radiation unit for a distance and is electrically isolated with the radiation unit. The metal plate is excited by the radiation unit to generate at least one resonance mode, and includes a hole penetrating the metal plate. Thus, the gain is enhanced, the bandwidth is increased, and multiple resonance modes are provided.
