The disclosed apparatus may include an antenna radiating structure that includes an active transparent mesh portion as well as a non-transparent antenna radiator portion. By combining transparent metal mesh and non-transparent metallic film into the antenna radiating structure, the disclosed apparatus results in improved radiation efficiency. Moreover, when overlaid on a transparent lens (such as with a pair of augmented reality glasses), the antenna radiating structure leaves the optical transparency of the lens largely unaffected due to the placement of the non-transparent metallic film. Various other implementations are also disclosed.

A multiband antenna for mobile devices that includes both energized and parasitically-coupled resonant elements. An energized element is fed radio frequency energy and resonates at a first frequency. A first parasitic element, arranged on a same surface as the energized element, is parasitically coupled to the energized element and resonates with at least a second frequency. A second parasitic element, arranged on a surface opposite the energized element resonates at a third frequency.
