Exercise 16

A parallel-plate transmission line is constructed of highly conducting plates of width w that are separated by a lossless dielectric of dielectric constant r and thickness d. Neglecting fringing effect, explain how the following should be changed if it is desired to double its characteristic impedance by changing only one parameter: (a) w , (b) d , and (c) r.
