1. A device comprising:
a housing;
a circuit board within the housing;
a Wi-Fi interface within the housing and mounted proximate to a first end of the circuit board, wherein the Wi-Fi interface operates within a first frequency band;
a High-Definition Multimedia Interface (HDMI) interface mounted proximate to a second end of the circuit board opposite the first end, wherein the HDMI interface radiates within the first frequency band; and
a conductive member positioned within the housing, proximate to a portion of the circuit board that is between the Wi-Fi interface and the HDMI interface, wherein the conductive member comprises a plurality of slots, each slot of the plurality of slots having a length associated with resonance within the first frequency band, and wherein a number of slots in the plurality of slots and a spacing between adjacent slots of the plurality of slots attenuates signals in the first frequency band associated with operation of the HDMI interface that are conducted across the conductive member to prevent interference to signals associated with the Wi-Fi interface by the signals associated with the HDMI interface.
