Analysis method for microstrip line power dividers with arbitrary branching circuit pattern

The transmission and reflection properties of 3-dB microstrip line power dividers with a straight-line and a curved branching circuit pattern have been analyzed based on the eigenfunction-weighted boundary integral equation method. Branching patterns can be arbitrary in this method. Theoretical values of scattering parameters were in reasonable agreement with initial experimental results at microwave frequencies. Theoretical and experimental results are presented.<<ETX>>
