The present invention discloses a miniature antenna that has a simple structure, compact dimension and high efficiency. The miniature antenna is comprised of a dielectric element made of a dielectric material, having a first surface and a second surface opposite to the first surface, a first electrode layer being laid on the first surface, and a second electrode layer being laid on the second surface. The first electrode layer connected to a signal feeding line and the second electrode layer, connected to a ground plane, are partially overlapped to form a region that functions as a capacitor. Thereby, the miniature antenna can transmit and receive signals. The capacitance and resonant frequency of the miniature antenna can be adjusted via varying the pattern of the electrode layers, varying the thickness or permittivity of the dielectric element or via varying the size of the overlapping areas of the two electrode layers.
