This article describes a fourth‐order 3‐D printed combline filter with a Chebyshev response, operating at central frequency 3 GHz and having a 3% fractional bandwidth. The filter is designed using the coupling matrix theory, fabricated, and experimental results are presented. Comparison between simulations and measurements shows good agreement. © 2017 Wiley Periodicals, Inc. Microwave Opt […]
