Example Embodiment
[0018] The technical solutions of the present invention will be described in detail below with reference to the drawings and specific embodiments. Example 1: First reference Figure 1~2 The described structure diagram of the ultra-wideband bandpass filter of the present invention using the simplified left-handed transmission line structure.
[0019] The ultra-wideband filter using the simplified left-handed transmission line structure of the present invention includes an input port 1, an output port 2 and at least one simplified left-handed transmission line structure unit on a PCB board. The input end is connected to the first microstrip line structure unit through a 50 ohm microstrip line 3, and the output end is connected to the last microstrip line structure unit through a 50 ohm microstrip line 4. Each microstrip line structure unit is composed of series inductance, parallel capacitance and parallel inductance. See the equivalent circuit model image 3 . L R Corresponds to ser...
Example Embodiment
[0022] Embodiment 2: Referring to FIG. 8, the grounded short microstrip line stubs of the filter of the present invention can have many different distribution forms. The grounded narrow microstrip transmission lines can be distributed on the same side or on the upper and lower sides of the main transmission line. It can be linear, polyline, or other shapes. The polyline-shaped curved section can point to the input end or the output end. Otherwise, the rest is the same as in Example 1.
