A five-element Chebyshev low-pass filter having high roll off, built u
sing coplanar waveguide open circuit stubs for the capacitive elements
, is investigated. Passband ripple within 1.5 dB and a stop-band rejec
tion of more than 45 dB is achieved. Comparison of the predicted and e
xperimentally measured results is presented and the agreement is good.
