Mobile device antennas with dielectric loading are described herein. In one example, a mobile device includes a ground plane, carried within an enclosure. An antenna is connected to the ground plane. Dielectric loading material is provided within at least a portion of an area defined between the ground plane and the antenna. The dielectric loading material results in a shortening of a required antenna length, thereby creating a recovered area, i.e., valuable space within the enclosure “recovered” by the use of dielectric loading material.
