T/CSTM 00990-2023 Test Method for Dielectric Constant and Dielectric Loss Angle Tangent in the Millimeter-Wave Band Using the Near-field Cavity Method
Abstract
Scope: This document specifies the test method for the dielectric constant and dielectric loss tangent of medium substrates in the millimeter wave band, including principles, environmental conditions, instrumentation, sample requirements, test steps, calculation formulas, system errors, precautions, and test reports. This document is applicable to testing the dielectric constant and dielectric loss tangent of sheet-like solid materials in the millimeter wave frequency range. Frequency test range: f = 25 GHz to 110 GHz; Dielectric constant test range: ε_r' = 2.0 to 20.0; Loss tangent value test range: tan?〖δ_ε 〗?〖=1.0×10(-4) to 1.0×10(-2) 〗; Temperature test range: -65 °C to 125 °C.
