Abstract

Finite element methods Green's function methods Impedance Magnetic field measurement Maxwell equations Microstrip Resonant frequency Scattering Transmission line matrix methods Waveguide junctions
The five-port annular junction is solved using field theory analysis with the aid of finite elements method. Novel model for fringing fields is presented. Fields distributions and scattering matrices are obtained. Two five-port microstrip annular junctions are simulated using IE3D, realized and the measured S-parameters are found to be in good agreement with theoretical ones.
