Title:
DIELECTRIC SUBSTRATE AND DIELECTRIC ANTENNA
Document Type and Number:
WIPO Patent Application WO/2021/020205
Kind Code:
A1
Abstract:
The present invention provides: a dielectric substrate which has a high relative dielectric constant over a wide temperature range from a low temperature to a high temperature, and which has excellent productivity and an excellent degree of freedom in shape, while having a low dielectric loss tangent; and a dielectric antenna. A dielectric substrate 2 according to the present invention is used in a dielectric antenna 1, and is composed of a dielectric elastomer composition that is obtained by blending a dielectric ceramic powder into an elastomer; the elastomer is a thermoplastic elastomer; and the dielectric substrate 2 is an injection molded body of the dielectric elastomer composition, and has a dielectric loss tangent of 0.01 or less and a relative dielectric constant of 5 or more at a frequency of 1 GHz at a temperature of 20°C.
