Abstract
A miniature antenna device includes a dielectric substrate having an upper side and an opposing lower side and at least one antenna element. The antenna element includes a first half-loop conductor strip disposed on the upper side of the substrate and a second half-loop conductor strip disposed on the lower side of the substrate. The first and second half-loop conductor strips are aligned complementarily one with the other to have a common center of curvature that is void of a ground plane. The antenna element further includes a director element disposed on the upper side of the substrate and spanning the first and second half-loop conductor strips, an input terminal disposed on the upper side of the substrate being electrically coupled to the first half-loop conductor strip, and a ground plane disposed on the lower side of the substrate being electrically coupled to the second half-loop conductor strip.
