Low VSWR Waveguide Twists

Waveguide, mawuwa nthawi zambiri amatanthawuza mitundu yosiyanasiyana ya ma waveguide achitsulo osasunthika komanso ma waveguide apamwamba. Pakati pawo, yoyambayo imatchedwa yotsekedwa waveguide chifukwa mafunde a electromagnetic omwe amatumiza amatsekeredwa mkati mwa chubu chachitsulo. Yotsirizirayi imatchedwanso open waveguide chifukwa mafunde a electromagnetic omwe amawongolera amakhala pafupi ndi mawonekedwe a waveguide. Mafunde oterowo amagwira ntchito yofunika kwambiri m’mauvuni a ma microwave, ma radar, ma satelayiti olankhulana, ndi zida zolumikizira mawayilesi a microwave, kumene amakhala ndi udindo wolumikiza ma microwave transmitters ndi zolandirira ku tinyanga tawo. Waveguide twist amatchedwanso waveguide torsion joint. Imasintha njira ya polarization mwa kutembenuza njira ya mbali zazikulu ndi zopapatiza pamapeto onse awiri, kotero kuti mafunde a electromagnetic adutsamo, njira ya polarization imasintha, koma njira yofalitsa imakhalabe yosasinthika.
Mukalumikiza ma waveguide, ngati mbali zazikulu ndi zopapatiza za ma waveguide awiriwo ndi zotsutsana, ndikofunikira kuyika mafunde opindikawa ngati kusintha. Utali wa mafunde opindika uyenera kukhala wochulukirachulukira wa λ g/2, ndipo utali waufupi usakhale wochepera 2 λ g (pomwe λ g ndi kutalika kwa mawonekedwe a waveguide).
