GB/T 12636-1990
Scope
This standard specifies the stripline test method for the complex dielectric constant of microwave dielectric substrates. This standard is suitable for testing the complex dielectric constant of various substrates (such as plastics, composite materials, ceramics, silicate and other single crystal materials, etc.) at microwave frequencies. Test frequency range: f=1~20GHz Test dielectric constant range: ε’=2~25 Test loss tangent range: tanδe=5×10-4~1×10-2
