Directional coupler component is important in the radio technology. It finds application in a signal sample for measurement or monitoring, antenna beam forming, and separating transmitted and received signals on phone lines. In this research, a CPW directional coupler has been designed based on multilayer MMIC technology. The CPW directional coupler was modelled on GaAS substrates and Polymide as the dielectrics. When the scale dimensions of the directional coupler component are minimized, the performance of the isolation factor parameters, coupling factors and directivity factors are improved. |
