Field and Wave Electromagnetics 2nd Edition by David Cheng

تمرين 75

Consider lossless stripline designs for a given characteristic impedance.
a) How should the dielectric thickness, d , be changed for a given plate width, w , if the dielectric constant, r , is doubled
b) How should w be changed for a given d if r is doubled
c) How should w be changed for a given r if d is doubled
d) Will the velocity of propagation remain the same as that for the original line after the changes specified in parts (a), (b), and (c) Explain.
