In this study, a reciprocal broadband four‐way spatial divider/combiner with coaxial probes entering a rectangular cavity is simulated, experimentally fabricated and tested. A combination of circuit model and full electromagnetic wave methods is used to simplify the design procedure by increasing the role of the circuit model and, in contrast, reducing the amount of full wave optimisation. The presented structure is compact and easy to fabricate. Keeping its return loss greater than 10 dB, the constructed combiner operates with a 100% bandwidth from 5 to 15 GHz. A through scenario is also analysed whereas both measured and simulated results indicate a negligible loss. The measurements are in good agreement with the simulations done by high frequency structural simulator software.
