Abstract A dual-band coaxial waveguide mode converter is investigated. In the converter, the TEM mode (Coa.TEM) and TM01 circular waveguide (Cir.TM01) mode are transformed simultaneously into TE11 coaxial waveguide (Coa.TE11) mode and TE11 circular waveguide (Cir.TE11) mode, respectively. The optimized geometrical dimensions are achieved by employing the mode coupling theory. A mode converter at 1.3 GHz and 5.0 GHz is designed, and conversion efficiencies of Coa.TEM−to-Coa.TE11 and Cir.TM01−to-Cir.TE11 are 99.88% and 99.70% at central frequency, respectively. Over the frequency ranges 1.15–1.51 GHz and 4.87–5.19 GHz, the conversion efficiency exceeds 90%. A good agreement between theoretical calculations and computer simulations is observed, demonstrating the feasibility of the dual-band mode converter.
