Abstract
A novel design technique to improve the directivity of a microstrip direction coupler by a meandered structure with dielectric cover is proposed in this paper. Increasing of even-mode phase velocity by the proposed meandering method structure with dielectric cover is reported for the first time. An analytical method to obtain closed-form equations of even-mode, phase velocity is developed. The proposed structure is verified by experiments.
