Magnitude of the transmission coefficient obtained from lossless electromagnetic and circuit simulations. In all three cases, red curve is for symmetric case, where blue and olive curves correspond to asymmetric cases for different sections with bigger and small SIRs, respectively. (a) the capacitor patch length of the lower SIR for the first sub-section increased/decreased 0.665 mm (Δ l1,l = ±0.19, l1,l = ±0.665 mm), while the second and third sub-sections being asymmetric by decreasing the length of the lower capacitive patch 0.19 l1,l for each SIR patch length individually; (b) the capacitor patch length of the lower SIR for the second sub-section increased/decreased 0.494 mm (Δ l1,l = ±0.19, l1,l = ±0.494 mm), while the first and third sub-sections being asymmetric by decreasing the length of the lower capacitive patch 0.19 l1,l for each SIR patch length individually; (c) the capacitor patch length of the lower SIR for the third sub-section increased/decreased 0.342 mm (Δ l1,l = ±0.19, l1,l = ±0.342 mm), while the first and second sub-sections being asymmetric by decreasing the length for the lower capacitive patch 0.19 l1,l of each SIR patch length individually.
