Embodiment Construction
[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. The following are only preferred embodiments and do not constitute a limitation to the protection scope of the present invention.
[0035] see figure 1 , is a flowchart of a design method for a dual-band non-uniform transmission line impedance transformer provided by the present invention. In this embodiment, the design method of a dual-band non-uniform transmission line impedance converter includes the following steps:
[0036] S1. Expand the characteristic impedance of each non-uniform transmission line of the impedance transformer with a truncated Fourier and obtain a normalized expression
[0037]
[0038] Among them, i is the distinguishing subscript of different circuits, A~E is the distinguishing subscript of each non-uniform transmission line in a circuit, Z 0 is t...
