Systems and methods are provided for an antenna coupler mechanism. The antenna coupler mechanism includes a first tuning leg, a second tuning leg, and a bottom plate. The first tuning leg includes a first inductive circuit element, the first tuning leg being configured to accept a radio frequency device in series with the first inductive circuit element. The second tuning leg includes a second inductive circuit element and a capacitive circuit element connected in series, the second tuning leg being connected electrically in parallel with the first tuning leg. In addition, the bottom plate includes a third inductive circuit element connected electrically in parallel with the first tuning leg and connected electrically in parallel with the second tuning leg, the bottom plate being configured to couple energy into a nearby structure.
