摘要
There is disclosed an antenna device including a dielectric substrate having a first, upper surface and a second, lower surface, a conductive groundplanc on the second surface or located between the first and second surfaces. At least two conductive feedlines are formed on the first surface and extend from feed points to predetermined radiating points at edge or corner parts of the first surface. The groundplane does not extend under the radiating points. The groundplane is configured as to extend between the radiating points and the feedlines may be widened at the radiating points. The antenna device provides broadband performance and good diversity within a small space.
