Abstract: An electrically-conductive rubber composition and article of manufacture having a component thereof. In one aspect, such article of manufacture is a pneumatic rubber tire of a toroidal shape having a cavity designed to be substantially enclosed by the toroidal shape of the tire and its closure completed by a rigid rim onto which the tire is designed to be mounted. In another aspect, such pneumatic tire contains such rubber composition positioned on or within a rubber innerliner of the tire; wherein the innerliner is a surface of said cavity. In a further aspect, said rubber composition is an annular strip of an electrically-conductive rubber composition on or within such tire innerliner. The said annular strip is intended to be an antenna for having a capability of receiving electromagnetic waves from outside the tire and of transmitting electromagnetic waves from the inside of the tire to the outside of the tire.
