This letter presents an innovative topology of evanescent mode filters with mixed electromagnetic coupling finalized to take full advantage of additive manufacturing techniques. A four-pole filter with two transmission zeroes was designed starting from a suitable equivalent circuit. The filter was built using a 3-D printer and measured. The good experimental results show the usefulness of the solution when in-line topologies are required.

Abstract
This letter presents an innovative topology of evanescent mode filters with mixed electromagnetic coupling finalized to take full advantage of additive manufacturing techniques. A four-pole filter with two transmission zeroes was designed starting from a suitable equivalent circuit. The filter was built using a 3-D printer and measured. The good experimental results show the usefulness of the solution when in-line topologies are required.File in questo prodotto:
