Abstract :
In this paper, a compact stepped-impedance resonator (SIR) transformer is proposed The implemented CB-CPW to SIW transition using the SIR transformer has shown a 50% reduction in size with only 2.09% reduction in the 15-dB fractional bandwidth as compared with using the quarter-wavelength transformer.
