Abstract

The design procedure for a microstrip six-port directional coupler on Epsilam-10 anisotropic substrate is described. An experimental 10 dB six-port directional coupler with centre frequency 1.1 GHz and bandwidth of 1.4 GHz has been designed, fabricated and tested. The measured scattering parameters have been found to be in good agreement with the theoretical predictions.
