<p>The present invention provides a highly dielectric elastomer composition which shows a high dielectric constant in a wide temperature range from low to high temperature and has a low dielectric loss tangent, and a dielectric antenna composed of the highly dielectric elastomer composition. A dielectric antenna including a molding of a highly dielectric elastomer composition composed of an elastomer and a highly dielectric ceramic powder mixed with the elastomer and an electrode formed on the molding. The highly dielectric ceramic powder of barium titanate·neodymium ceramic has a temperature coefficient ± (unit: 1/°C) of a dielectric constant of the ceramic powder on 25°C standard ranging from -200×10 -6 to 100×10 -6 over a temperature range from-40°C to 100°C. The dielectric constant of the highly dielectric elastomer composition is ‰§7 and a dielectric loss tangent thereof is ‰¦0.01.</p> |
