A microstrip line is 1 cm thick and 1.5 cm wide. The conducting strip is made of brass (σc = 1.1 X 107 S/m) while the substrate is a dielectric material with εr = 2.2 and tan θ =0.002. If the line operates at 2.5 GHz, find:
(a) Zo and εeff,
(b) αc and αd,
(c) The distance down the line before the wave drops by 20 dB.
