Abstract
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.
Claims18
A mobile device, comprising:
- a ground plane, carried within an enclosure of the mobile device;
- an antenna, carried within the enclosure of the mobile device;
- dielectric loading material, fastened in a stacked relationship between at least a portion of the ground plane and at least a portion of the antenna;
- and
- a recovered area, sized as a function of the dielectric loading material, the recovered area located between the antenna and the enclosure, and sufficient in size to reduce adverse hand detuning of the antenna.
A mobile device, comprising:
- a printed circuit board to support components of the mobile device;
- an antenna supported a distance from the printed circuit board;
- a first dielectric loading material, contained within an area defined between the printed circuit board and the antenna;
- a second dielectric loading material, located adjacent to the antenna, and on a side of the antenna opposite the first dielectric loading material, to thereby sandwich at least a portion of the antenna between the first dielectric loading material and the second dielectric loading material;
- and
- a recovered area that is sized as a function of the first and second dielectric loading materials, located between the antenna and an enclosure of the mobile device, and of sufficient size to reduce adverse hand detuning of the antenna.
A wireless communications device, comprising:
- a ground plane, carried within an enclosure of the wireless communications device;
- an antenna, carried within the enclosure of the wireless communications device;
- a first dielectric loading material, contained within at least a portion of an area defined between the ground plane and the antenna;
- a second dielectric loading material, located adjacent to the antenna, and on a side of the antenna opposite the first dielectric loading material;
- and
- a third dielectric loading material, located between the antenna and a portion of the enclosure nearest to the antenna and being sized to prevent adverse hand detuning that would result without the third dielectric loading material.
