The invention discloses a micro-strip dual-passband filter capable of realizing X waveband and Ku waveband communication. A first sub micro-strip filter working in a Ku waveband comprises at least three ring resonators that are edge-coupled through electromagnetism in sequence, and each of the ring resonators is provided with an opening end; the three ring resonators comprise a first resonator (3), a second resonator (4) and a third resonator (5); a second sub micro-strip filter working in an X waveband also comprises at least three ring resonators that are edge-coupled through electromagnetism in sequence, and each of the ring resonators is provided with an opening end; the three ring resonators comprise a fourth resonator (6), a fifth resonator (7) and a sixth resonator (8); an input unit (1) is edge-coupled with the first resonator (3) and the fourth resonator (6) through electromagnetism; and an output unit (2) is edge-coupled with the third resonator (5) and the sixth resonator (8) through electromagnetism. The micro-strip dual-passband filter is used for screening microwave signals and filtering out useless or even harmful signals to ensure reliable transmission of useful signals, and the micro-strip dual-passband filter has the characteristics of small volume, simple structure and high reliability.
Description
technical field [0001] The invention relates to the field of filters, in particular to a microstrip double-passband filter across X-band and Ku-band. Background technique [0002] Microstrip filters are generally used in electronic equipment such as microwave communications, satellite communications, radar equipment, and aerospace to filter out channel clutter to achieve normal transmission of required microwave signals and suppress out-of-band clutter signals. [0003] The traditional bandpass planar filter currently on the market adopts a microstrip parallel line structure, which has a large volume and a small passband span. When realizing cross-X-band and Ku-band communication, the structure is complex and difficult to implement. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a cross-X band and Ku band microstrip double-pass band filter, which has the characteristics of small size, si...
