Abstract


The paper proposes an implementation of quasi-lumped reactive elements by using electromagnetocrystalline (EC) discontinuities. Characteristics of EC discontinuities and traditional microstrip structures are compared that illustrate a significant rise (by the factor of 1.5…4) of values of reactances caused by their implementation with EC discontinuities. The software package CST Microwave Studio has been used for simulation. Experimental characteristics for the proposed and traditional quasi-lumped inductances are presented. In addition, an error of quasi-lumped element parameter is analyzed and possible minimization of the error is shown.
