Abstract :
A unilateral finline-the asymmetrical structure finline-is discussed. In addition to providing better electromagnetic isolation, this structure solves problems of mechanical and thermal resistance encountered with the traditional line. It provides better electromagnetic performances than the traditional line, while leaving an additional degree of freedom to obtain the characteristic parameters. Calculation software is used to simulate this type of structure, with results close to experimental measurements. The study was completed by producing two circuits: a 20 GHz bandpass filter and a balanced mixer
