An electronic device includes a first region corresponding to a first part of the electronic device, and a second region corresponding to a second part of the electronic device. The second region has a lower temperature than that of the first region. An antenna is located over at least the first region and optionally the second region of the electronic device. A conductor is arranged over at least the first region of the electronic device to transmit heat from the first region to the second region. The conductor operates in conjunction with the antenna and is adjacent to at least a part of the antenna to prevent the conductor from interfering with the antenna.
