Abstract:
1. A monopole slot antenna, comprising: a dielectric substrate; a first ground plane being disposed on a first surface of the dielectric substrate; a second ground plane being disposed in a vicinity of the first ground plane and electrically connected to the first ground plane via a metal wire, and the metal wire having a section being disposed on a second surface of the dielectric substrate, wherein the second surface is opposite to the first surface; a monopole slot being disposed only on the first ground plane, and the monopole slot having an open end disposed at an edge of the first ground plane and near the metal wire that connects the first and the second ground planes, and the section of the metal wire is connected to the first ground plane at an electric contact, wherein the electric contact has a distance at least one half of the length of the metal wire to the open end of the monopole slot; and a microstrip feedline being disposed on one surface of the dielectric substrate opposite to the first ground plane, and the microstrip feedline having an end extended across the monopole slot and another end connected to a signal source.
