Mechanically Reconfigurable Microstrip Lines Loaded with Stepped Impedance Resonators and Potential Applications
Figure 3
Microstrip line loaded with folded SIRs for the code “101” (a) and lossy electromagnetic simulation of the transmission coefficient corresponding to the indicated codes (b). The top and bottom substrates are Rogers RO3010 with thickness mm, dielectric constant , and loss tangent tan . The dimensions are line width mm, corresponding to a characteristic impedance close to 50 Ω; for the folded SIRs, (2.5 GHz) = 2 mm, (2.6 GHz) = 1.8 mm, (2.7 GHz) = 1.64 mm, mm, mm, (2.5 GHz) = 3.26 mm, (2.6 GHz) = 3.06 mm, (2.7 GHz) = 2.9 mm, and = 6 mm.
