Abstract :
This paper is dedicated to the design of the fourth-degree pseudo-elliptic cross-coupled filter based on half-wavelength folded substrate integrated resonators using multilayer PCB substrate. Also a new simple idea of obtaining negative coupling coefficient using positive coupling structure for folded waveguides is introduced and applied.
