Abstract
An antenna comprises a ground plate, a first plate, a connector, and a signal feeder having two terminals respectively electrically connected to the ground plate and the first plate. The first plate is set above the ground plate and comprises first, second, and third resonance regions with respective dimensions corresponding to wavelengths of first, second, and third frequencies at which the antenna operates. A connection region is connected to the first, second, and third resonance regions. The connector has two opposite ends respectively connected to the ground plate and the connection region. The first, second, and third frequencies respectively correspond to first, second, and third frequency bands of the antenna. The second frequency is close to the third frequency such that the second frequency band and the third frequency band are partially overlapped to cause the second frequency band and the third frequency band to merge.
