A broad‐band power divider using coaxial probes and a radial waveguide is presented. The simple modeling of this power divider and design method based on equivalent circuits has been developed. A four‐way radial waveguide power divider has been designed, fabricated, and measured. Close agreement is obtained between the measured results and the simulated results. The measured 15‐dB return loss bandwidth of the broad‐band multiple‐port structure is demonstrated to be 81.5% and its 0.5‐dB insertion loss bandwidth 84.6%. © 2007 Wiley Periodicals, Inc.
