Abstract

The invention discloses a low-profile magnetoelectric dipole antenna structure based on a bent magnetic wall, and the structure comprises a radiation unit part and a vertically-inverted-L-shaped feedpart and a common-ground coplanar waveguide feed part. The radiation unit part comprises a pair of trapezoidal electric dipoles and a pair of short-circuit bent magnetic dipoles, wherein the electricdipole are horizontally placed a top dielectric substrate, and the magnetic dipoles are implemented through the forming of metalized via holes on the dielectric substrate. The magnetic dipoles and theelectric dipoles are placed in a mutually perpendicular manner. A horizontal part of the vertically-inverted-L-shaped feed part is a cap-shaped paster, and a vertical part of the vertically-inverted-L-shaped feed part is implemented through the form of metalized via holes. The common-ground coplanar waveguide feed part is located on a bottom dielectric substrate, wherein the upper surface of thedielectric substrate is a metal ground, and the lower surface of the dielectric substrate is provided with two parts: a signal line of a common-ground coplanar waveguide and a ground line. The upper and lower metal grounds are connected with the metalized via holes. The antenna is simple in structure, is easy to integrate, is high in stability, is low in profile, and is suitable for a mobile positioning system in a modern wireless communication system.
