Mafambiro eWaveguide

Izwi reRF waveguide, rinowanzo sanganisira marudzi akasiyana-siyana emafungu esimbi asina chinhu uye mafungu emvura pamusoro. Pakati pawo, rekutanga rinonzi closed waveguide nekuti electromagnetic wave yarinotumira yakavharirwa mukati mechubhu yesimbi. Rekupedzisira rinonziwo open waveguide nekuti electromagnetic wave yarinotungamira yakavharirwa kumucheto kwechimiro chewaveguide. Mafungu eradio frequency akadaro anoita basa rakakosha mumaovheni emicrowave, maradar, masateliti ekutaurirana, uye michina ye microwave radio link, uko vane basa rekubatanidza ma microwave transmitters nema receivers kuma antenna avo. Waveguide twist inonziwo waveguide torsion joint. Inoshandura gwara re polarization nekudzosera gwara remativi akafara uye akamanikana kumativi ese, kuitira kuti electromagnetic wave ipfuure nepakati payo, gwara re polarization rinoshanduka, asi gwara rekuparadzira harina kuchinja.
Pakubatanidza ma "millimeter wave wave guides", kana mativi akafara uye akamanikana ema "waveguides" maviri akatarisana, zvakakosha kuisa "twisted waveguider" iyi se "transition". Kureba kwe "waveguided twist" kunofanira kunge kuri "integer multiple" ye λ g/2, uye kureba kupfupi hakufanirwe kunge kuri pasi pe 2 λ g (apo λ g iri "wavelength" ye "waveguides").

Kushandiswa:

MaWaveguide twists ane mashandisirwo akasiyana-siyana, kunyanya nekuda kwehunhu hwawo hwepamusoro hwekushanda, senge huwandu hwekutumira mameseji uye kuderera kwechiratidzo, izvo zvinoita kuti aite basa rakakosha mumauto, mundege, kutaurirana nesatellite, masisitimu eradar, mifananidzo yemafungu e millimeter uye minda yekupisa/kubika mumaindasitiri.

QualwaveZvishandiso zve waveguide twists zvinofukidza huwandu hwema frequency hunosvika 110GHz, pamwe neWaveguide Twists yakagadzirirwa zvinoenderana nezvinodiwa nevatengi. Kana uchida kubvunza nezve rumwe ruzivo nezvechigadzirwa, unogona kutitumira email uye tichafara kukushandira.
