Characterization of Thin Film Coupled Microstrip Line for Terahertz Frequency - Range

The dispersion characteristics and loss analysis of coupled microstrip line on low loss thin film cyclic-olefin copolymer dielectric substrate are investigated in this paper. The even-mode and odd-mode capacitances are computed using closed-form expressions derived from conformal mapping method. The frequency dependent parameter- impedance, effective relative permittivity, dielectric loss and conductor loss for even-mode and odd-mode are computed to analyze the coupled microstrip line.
