TWANDIKIRE NONAHA

Uduce twa RF waveguides ni ibikoresho byohereza ingufu ziva ahantu hamwe zijya ahandi. Aho gutanga ingufu mu mwanya wose nk'antene, microwave waveguides ishobora gufunga ingufu mu cyuma gifunze, ibyo bikaba bigabanya cyane igihombo mu gihe cyo kohereza ingufu. Uduce twa milimetero waveguides dushobora kumvikana nk'antene ikomeye cyane, kandi ingufu zishobora gukwirakwira gusa muri waveguides, kandi ntizishobora gukwirakwira ahandi.
Impinduka ya Waveguide ni imwe muri waveguide, ikoreshwa cyane mu nzego zitandukanye, harimo ariko ntigarukira gusa ku itumanaho rya mikoroonde, sisitemu za radar, satelite z'itumanaho n'ibikoresho byo guhuza radiyo ya mikoroonde. Hari ubwoko bwinshi bw'impinduka za waveguide, akenshi zifite imikorere myiza, umuraba usanzwe uhagaze VSWR≤1.2 muri bandwidth yuzuye ya waveguide, ibikoresho by'ibanze birimo umuringa, aluminiyumu, uburyo bwo gutunganya ubuso bwa silver plating, zahabu plating, nickel plating, passivation, conductive oxidation, nibindi.

Ibiranga:

Ikintu gisanzwe cya transition waveguide ni uko ibyambu bibiri bikoresha ubwoko butandukanye bwa waveguide mu guhindura ubwoko butandukanye bwa waveguide. Urugero:
1. Abahindura imiyoboro ya microstrip: Abahindura imiyoboro ya microstrip bakoreshwa cyane mu gutahura imiyoboro ya milimetero y’umuraba n’imiyoboro ya hybrid, ndetse no mu guhuza imiyoboro ya waveguide n’imiyoboro ya planar kugira ngo harebwe ko inzira ebyiri zo kohereza zihuye neza.
2. Guhindura imiterere y'umuraba uva ku miraba ibiri ujya ku miraba ibiri: Imiraba ihindura imiterere y'umuraba ishobora guhuza imiraba ibiri n'imiraba ibiri, igatanga igihombo gito cyo kwinjira no guhuza neza. Ubwo bwoko bw'umuraba uhindura imiterere bukwiriye gushyirwa muri laboratwari no gupima imiterere y'umuraba uhindura imiterere y'umuraba ibiri n'ibikoresho byawo.
3. Impinduka y'umurongo w'urukiramende: Umurongo w'urukiramende uhindura uburyo bwa TE10 mu buryo busanzwe bw'umurongo w'urukiramende ukajya muri TE11 mu murongo w'urukiramende. Iri hinduka ni ingenzi mu kohereza neza ibimenyetso biva ku murongo w'urukiramende usanzwe ukajya ku murongo w'urukiramende, cyane cyane mu bikorwa aho ihinduka ry'uburyo bwihariye rikenewe.

QualwaveImpinduka z'ibikoresho byo kuyobora umuyoboro w'amazi zifata intera ya frequency kugeza kuri 220GHz, ndetse n'impinduka z'umuyoboro w'amazi zikozwe mu buryo bwihariye hakurikijwe ibyo abakiriya bakeneye.
