Design of Microstrip Couplers using Novel Artificial Dielectrics

Microstrip coupled line is more lossy than waveguide, coaxial line and strip line because it is open lines. As the lines are close together and very narrow, it has lower power handling capability and has lower quality factor Q. After reviewing past research work, we have concluded that the DGS and fractal DGS are good choices for the miniaturization of microstrip components and enhancing the performance parameter of the same. In addition to DGS and fractal DGS, Meta materials are also good choice.
