Abstract
A dual frequency coupling feed antenna includes a substrate. There are an upper dipole radiative conductor, a lower dipole radiative conductor, a ground line and a ground reflective conductor disposed on the second surface of the substrate and the two dipole radiative conductors are not electrically connected to each other. The first surface of the substrate has a coupling conductor, a signal line and a feed-matching conductor. The coupling conductor extends parallel to the upper dipole radiative conductor. The ground reflective conductor is located at a side-edge of the dipole radiative conductor and the feed-matching conductor is located on the path of the signal line.
