A New Theoretical Approach of Studying Resonances in Single Finline Transitions

In this article an innovative method of studying and removing the resonances, inherently exhibit by some waveguide to microstrip transitions, is presented. By modeling equivalent circuit, new approach allows obtain constructive parameters a finline transition, only using values resistance capacitance components circuit. This procedure will allow small microwave design Companies realize these transitions implementing circuit analysis software, not having afford electromagnetic which are very expensive time-consuming. A full 3D confirms that simulation results in excellent agreement with obtained equations discussed work.
