Embodiment Construction
[0017] The asymmetric C-band dual-mode bandpass filter of this embodiment is as attached image 3 As shown, the side length of the pentagonal loop filter (3) in the present embodiment is 5.64mm, which is a full-wavelength resonator; the width of the non-orthogonal input and output feeders (1), (2) is 0.3mm , The coupling gap between the input and output feeder and the resonator is 0.2mm.
[0018] The pentagonal loop filter (3) is connected to the non-orthogonal input and output feeders (1) and (2) through coupling; the tree-shaped fractal perturbation is loaded on the left and right inner corners of the upper side of the ring, and the tree-shaped fractal perturbation is carried out first The two-branch primary fractal (5), on this basis, the secondary fractal is performed to obtain the two-branch secondary fractal structure (6); by adjusting the size of the coupling gap (4) between the input and output feeder and the resonator, it can be adjusted The coupling coefficient of t...
