STUDY OF COUPLING COEFFICIENT & DIRECTIVITY OF THE MICROSTRIPLINE COUPLER

Abstract

The coupling coefficient, directivity and the attenuation constant etc. are to be studied in this present paper. The microstrip directional coupler and its characteristic parameters have also been analytically studied. An ideal microstrip directional coupler makes use of the basic feature that power flowing in one direction in the main transmission line induces a power flow in only one direction in the secondary line.
