Experimental confirmation of the modal filtration in four- and five-conductor microstrip lines

An experimental confirmation of modal filtration based on multiconductor microstrip lines is executed. Authors designed four- and five-conductor prototypes of modal filters (MF), which have the maximum amplitude of the decomposition pulses of 12.6 and 15.3 times less in comparison with the initial signal. The results showed the prospect of research of multiconductor MF because addition of conductors to the initial structure additionally (up 2.3 times) decreases the amplitude of the initial signal at the end of the active conductor.
