A microstrip transmission line is to be used as a capacitor of 4 pF at 800 MHz. The PCB dielectric is 3.6. The microstrip dimensions are h = 0.0625 in, w = 0.13 in, and t = 0.002 in. What is the characteristic impedance of the line?
(a) 48.9Ω
(b) 12.3Ω
(c) 54.3Ω
(d) 65.7Ω
This question was addressed to me by my school principal while I was bunking the class.
I would like to ask this question from Transmission Lines as Circuit Elements in section Transmission Lines of Avionics
