Circular Symmetric Coupled Microstrip Transmission Lines

The Circular Symmetric Coupled Microstrip Transmission Lines (CSCMTL) are introduced as a new kind of coupled microstrip transmission lines. A simple method is proposed to determine the capacitance matrix of CSCMTLs. In this method the laplace's equation is solved analytically using the Fourier series expansion. Finally, the properties of CSCMTLs and the validation of the proposed method are studied using an example.
