Abstract :
This paper presents a synthesis method for short-circuited waveguide orthomode transducers (OMTs). An equivalent circuit model of slot-coupled square waveguide T-junction is initially proposed, and useful formulas are derived for synthesis of the single-band OMT. Then a dual-band OMT connected with two filters is further designed using the circuit model and the synthesis theory for a filter matched with a complex load.
