Abstract
The present invention discloses a combination patch antenna element and bowtie-shaped slot antenna element together disposed upon a first major surface of a dielectric element. The bowtie-slot antenna element is defined upon the dielectric element within a boundary of the patch antenna element. The bowtie-slot antenna element defines a first antenna electrical resonance frequency characteristic, and the patch antenna element defines a second antenna electrical resonance frequency characteristic. The combination patch antenna element and bowtie-shaped slot antenna element are provided in relation to a ground plane element, such as provided by a printed wiring board of a wireless communications device. An additional optional feature of the antenna includes a plurality of conductive pattern enhancement elements disposed on an opposite side of the dielectric element.
