In addition to the specific applications covered, the technology may be applied to the generic problem of antenna tuning.

Detuning

The system may be more tolerant to environmental detuning or the effect of the product casing on the antenna performance.

Cost

The antenna may be made with a greater manufacturing spread and there is no requirement for a separate tuning circuit.

Efficiency

More efficient antennae may be employed in the product without detrimental effects.
