This Letter presents a four-way hybrid substrate integrated waveguide/microstrip-line power divider circuit based on the double microstrip-slot coupling. By slotting between T branch and loading isolation resistance, the isolation and output voltage standing wave ratio between non-adjacent ports is improved. By putting four output ports on the same side, the practicability of the circuit is improved. The test results show that the input return loss is >17.5 dB and insertion loss is <2 dB in 9–10.5 GHz.
