1. A wireless device, comprising:
- a substrate;
a first portion of a radiating element patterned onto a first side of the substrate;
a second portion of the radiating element patterned onto a second side of the substrate, wherein the first and second portions are patterned as a continuous conductive element;
a feed line capacitively coupled to the radiating element; and
a via line coupled to the radiating element, the via line further coupled to a reference ground,wherein the radiating element is positioned outside of a footprint of the reference ground.
