  • Conductive rubber antennas having improved physical and electrical properties
    Patent number: 4246217
    Abstract: A radio antenna is made of conductive rubber. Uncured rubber is doped with conductive high structure carbon black in proportions greater than normally required to attain the desired volume resistivity. The doped rubber is milled at high shear until the standard deviation of volume resistivity is reduced below a predetermined value in the finished antennas. A copper-containing metallic stud is embedded in at least one end of the uncured antennas and is bonded to the rubber by vulcanization during curing of the rubber. The antenna has improved physical properties, uniformity of volume resistivity, and reduced resistivity variation with stress.
