The impedance matching of the antenna structure (10) is controlled easily. No external matching element is required. With the multi-trace and grounded-short-circuit design of the antenna structure (10), the better resonance in the LTE full band is obtained.

Portions of one or multiple antenna elements can be photo-etched on opposite sides of the substrate to provide an additional degree of freedom in terms of antenna placement, spacing, and rotation angle.
