A field device in an industrial process control system having an electrically grounded housing with an electrical circuit located within the housing is described. The electrical circuit includes wireless communication circuitry and is electrically isolated from the housing. The field device also includes an antenna that is attached to the housing and a cable having a shield positioned between the wireless communication circuitry and the antenna. The cable provides electrical communication between the electrical circuit and the antenna. The electrical circuit is electrically isolated from the housing, and the shield of the cable is electrically grounded to the housing.
