Abstract
A radio module for use in an electronic device is disclosed. The radio module has a shield for reducing electromagnetic interference on the radio module. The shield may include a heat-spreading layer made of a material including graphite. The heat-spreading layer may spread heat generated by the radio module. The shield may also include a reflective layer overlapping the heat-spreading layer and configured to reflect electromagnetic energy to the heat-spread layer. The heat-spreading layer is also configured to absorb at least a portion of the electromagnetic energy, thereby reducing the electromagnetic interference on the radio module.
Claims25
A radio module configured for use in an electronic device, the radio module having a shield configured to reduce electromagnetic interference on the radio module, the shield comprising:
- a heat-spreading layer made of a material including graphite, the heat-spreading layer configured to spread heat generated by the radio module;
- a reflective layer overlapping the heat-spreading layer and configured to reflect electromagnetic energy to the heat-spread layer, wherein the heat-spreading layer is also configured to absorb at least a portion of the electromagnetic energy, thereby reducing the electromagnetic interference on the radio module;
- and
- wherein at least a portion of the shield is disposed between the radio module and a display module.
An electronic device comprising:
- a radio module including a first component set;
- and
- a first shield covering the radio module, the first shield including a heat-spreading layer, the heat-spreading layer comprising a material including graphite, the heat-spreading layer configured to spread heat generated by the first component set and to absorb electromagnetic energy for reducing electromagnetic interference on the radio module;
- and
- an enclosure member electrically coupled with at least a portion of the first shield, the enclosure member configured to be coupled with at least one of the radio module and the first shield wherein the enclosure member is further configured to support a display module.
