Loss tangent (tan(δ)) is a measure of signal loss as the signal propagates down the transmission line. range of wavelengths, the permittivity of low-loss materials will generally slowly decrease as frequency increases, and the loss tangent will generally increase as frequency increases, in many cases in a linear fashion. For dielectric materials , and :. 5 Dielectric constant permittivity @ 1GHz 3. @ 10 GHz (Bereskin Stripline) 0. Therefore, good radar absorbent materials usually require a large dielectric loss tangent (ε"/ε') and magnetic loss tangent (μ"/μ'). Loss tangent for FR4 is not tightly controlled - in fact, it isn't even loosely controlled. Compared to other materials that are specialized for high frequencies, dispersion actually increases the signal speed at higher frequencies, thus decreasing the propagation delay at higher frequencies. 1(a) with a commercial program, CST Microwave Studio TM 2009 [16]. Most printed circuit boards are manufactured using glass-reinforced epoxy laminate as the substrate.
