Webexamples: substrates with low (2) and high (9.6) relative dielectric con-stants.2 The top cover tends to reduce the impedance. When the ratio of the distance from the top cover to the dielectric substrate and the substrate thickness [(H – h)/h] is greater than 10, the enclosure effects can be con-sidered negligible. The characteristic Webis a function of a substrate dielectric constant ε r: 𝑟+0.67 (4) Attenuation sources of practical microstrip lines are due to the effects of radiation and finite conductivity of the conductor lines. In addition, energy in a microstrip is depending on the dielectric constant ε r, substrate thickness h, and the circuit geometry.
