Numerical method for determination of microstrip interdigitated coupler design parameters
Abstract
A method of determining design parameters for the microstrip interdigitated (Lange) coupler is presented. Parameters investigated include coupling coefficients, odd and even mode velocities, and characteristic impedance. A general method of analysis is reviewed, convergence of the method is studied, and a computer program implementing this analysis along with supporting test data are presented. Test results indicate a good agreement between measured and predicted coupling and directivity for the interdigitated couplers.
