Abstract
This letter presents the design and electrical measurement results of a novel compact diplexer design in Ku-band. The proposed diplexer is based on $\text {TM}_{01\delta }$ mode dielectric resonators (DRs). A fourth-order filter with one triplet section for each channel is used. An additively manufactured inset is used for each filter, which contains the resonators and the required support structure and is printed from two materials in one piece. The chosen arrangement enables a compact design and simple assembly. To validate the concept, the design, fabrication, and measurement of the fourth-order dielectric diplexer are presented.
