A mobile communication device. An antenna provides an output signal including a first resonance frequency and a wavelength. A printed circuit board (PCV) includes a metal grounding face and a layout face opposite the metal grounding face and is coupled to the antenna at a first node. A metal module is coupled to the metal grounding face at a second node. A distance between the first node and the second node is determined by the wavelength.
