Abstract
A wireless device may use two communication interfaces that utilize frequencies within the same band. As a result, a first communication interface such as an HDMI interface may interfere with operation of a second communication interface such as a WiFi interface. A conductive member is placed between the communication interfaces to reduce this interference. The conductive member has multiple slots, each slot having dimensions that cause resonance at a frequency used by the first communication interface. The number and spacing of the slots corresponds to the strength of signals used by the second communication interface. Placement of the conductive member between the first and second communication interfaces enables the conductive member to attenuate signals from the second communication interface that would interfere with the frequency used by the first communication interface.
