Quasi-static analysis of the eigenmodes of an array of coupled slot transmission lines

摘要

The problem of the eigenmodes of an infinite 2D array of slot transmission lines operating in the quasi-periodic mode is solved. The boundary-value problem is reduced to a system of integral equations for longitudinal components of the electric current on metal conductors and the magnetic current in slots. The system of integral equation is solved in the static approximation at the first stage and, afterwards, the solution to the electromagnetic problem is found using the Galerkin method. The results of the numerical analysis of the dependences of eigenmode propagation constants on geometric parameters of the structure and phase shifts between the array channels are analyzed.
