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