Abstract
An antenna assembly includes a conductive plate having a slot formed within the conductive plate. A conductive coupling element is positioned within the slot of the conductive plate to form a slot antenna structure with the conductive plate. At least one conductive radiator element is positioned outside of the slot. An antenna feed structure is electrically coupled to the conductive coupling element and the at least one conductive radiator element. The antenna feed structure is configured to simultaneously resonate the slot antenna structure and the at least one conductive radiator element. The slot antenna structure and the conductive radiator element work in combination to resonate at substantially similar (e.g., overlapping) RF communication bands or at different RF communication bands.
