Abstract
Antenna apparatus and methods of use and tuning. In one exemplary embodiment, the solution of the present disclosure is particularly adapted for small form-factor, metal-encased applications such as smartphones or tablets (and 'phablets') utilizing near field communication (NFC) interfaces. The solution increases the effective size of the antenna without requiring any significant additional space or other structural modifications to the host device (such as changes to the device's metal case or size), while still maintaining a high degree of electrical performance (including a high Q factor).
