Document Type and Number:
Japanese Patent JP7082304
Kind Code:
B2
Abstract:
Provided is a dielectric waveguide capable of reducing electromagnetic wave penetration. The disclosure relates to a dielectric waveguide comprising: a center dielectric A1; a dielectric layer A2 surrounding the center dielectric A1; and a dielectric layer A3 surrounding the dielectric layer A2, the center dielectric A1 comprising polytetrafluoroethylene, the center dielectric A1, the dielectric layer A2, and the dielectric layer A3 having relative permittivities at 25°C and 6 GHz represented by εA1, εA2, and εA3, respectively, εA1, εA2, and εA3 satisfying the following: εA1 is 2.20 or lower; εA2 is 1.90 or lower; εA3 is 1.55 or lower; and εA1 > εA2 > εA3 is satisfied.
