Summary: 
A hybrid-mode analysis of cylindrical microstrip line is presented based on Extended Spectral Domain Approach. The analysis incorporates the effects of the edge singularities properly and can afford the efficient and accurate calculation method for the characteristic impedances in addition to the phase constants of cylindrical microstrip line with zero- and finite-thickness conductor. The numerical results obtained by this method have revealed the effect of conductor thickness and curvature ratio of substrate on the characteristics of single and coupled cylindrical microstrips.
