Millimeter-Wave Broadband Power Divider Using Substrate Integrated Coaxial Line

摘要

A millimeter-wave broadband power divider using substrate integrate coaxial line (SICL) structure is investigated, fabricated and measured. The performance of power dividers with different kinds of transmission lines is compared in this study. Simulation and measurement results show that the fabricated SICL power divider prototype achieves wider working bandwidth than the SIW power divider and lower insertion loss than microstrip power divider.
