Claim:
1. A resonant structure comprising: an inductive section configured to inductively couple to an interior antenna, the inductive section comprising a first u-shaped end section, a u-shaped middle section, and a second u-shaped end section arranged in series in an electrically conductive path, wherein the first and the second u-shaped sections are configurable to adjust the inductance of the resonant structure, the interior antenna configured to be contained in a device package; and a capacitive section configured to capacitively couple to a ground plane so as to resonate in combination with the ground plane at a desired frequency, the ground plane being comprised in a vehicle chassis, the capacitive section further configured to be penetrated by an electrically conductive fastener, the electrically conductive fastener fastening the capacitive section to the ground plane via a dielectric penetrated by the electrically conductive fastener; the inductive section and the capacitive section being communicatively coupled to each other.
