Waveguide Twists RF Microwave Millimeter Wave Radio

RF waveguide, mawuwa nthawi zambiri amakhudza mitundu yosiyanasiyana ya mafunde achitsulo opanda kanthu ndi mafunde a pamwamba. Pakati pawo, woyamba amatchedwa closed waveguide chifukwa mafunde amagetsi omwe amatumiza amakhala otsekeredwa mkati mwa chubu chachitsulo. Womalizayu amatchedwanso open waveguide chifukwa mafunde amagetsi omwe amatsogolera amakhala otsekeredwa kuzungulira kapangidwe ka mafunde. Mafunde otere a wailesi amagwira ntchito yofunika kwambiri mu uvuni wa microwave, ma radar, ma satellite olumikizirana, ndi zida zolumikizira wailesi ya microwave, komwe ali ndi udindo wolumikiza ma transmitter ndi ma receiver a microwave ku ma antenna awo. Kupotoka kwa mafunde kumatchedwanso waveguide torsion joint. Kumasintha njira ya polarization potembenuza njira ya mbali zazikulu ndi zopapatiza kumapeto onse awiri, kotero kuti mafunde amagetsi amadutsamo, njira ya polarization imasintha, koma njira yofalitsira siinasinthe.
Mukalumikiza ma waveguide a millimeter, ngati mbali zazikulu ndi zopapatiza za ma waveguide awiriwa zili moyang'anizana, ndikofunikira kuyika ma waveguide opotoka awa ngati kusintha. Kutalika kwa ma waveguide kuyenera kukhala nambala yambiri ya λ g/2, ndipo kutalika kochepa sikuyenera kuchepera 2 λ g (komwe λ g ndiye kutalika kwa ma waveguide).
