Abstract

In this article, designs and analyses of several CCPW (Cylindrical CPW) discontinuities have been realized as microwave reactive elements. The quasi-TEM characteristic parameters of CCPWs have been obtained by CMT (Conformal Mapping Techniques) which provide satisfactory accuracy at microwave frequencies and lead to closed-form analytical solutions suitable for CAD software packages. Then these discontinuities have been simulated in CST Microwave Studio 2006 in order to obtain inductance, capacitance and also input impedance versus frequency and physical dimensions of the elements. The results show that CCPW discontinuities can be used successfully as reactive elements for related applications.
