A wireless device ( 100 ) includes a first circuit board ( 102 ), a second circuit board ( 104 ), and a distributed load ( 106 ) having an inductive coupling ( 112 ) and a capacitive coupling ( 114 ). The inductive coupling ( 112 ) and the capacitive coupling ( 114 ) form a parallel resonance at predefined frequencies of interest. The second circuit board ( 104 ) includes an antenna ( 116 ) for receiving and transmitting radio waves.
