Abstract: The paper presents the results of electromagnetic and mechanical numerical calculations and experimental prototyping of Y- and O-shaped dielectric microwave beads made from the Rexolite 1422 and Ultem PEI 1000. The beads are designed to be used in 1.85/0.804 mm air circular coaxial connectors with an operating frequency range of 0 to 67 GHz.

Keywords: dialectic bead, dielectric microwave hub, coaxial connector, cut-off frequency

Funding: This work was supported by the Ministry of Science and Higher Education of the Russian Federation, project FTWM-2023-0014, dated January 16, 2023.
