Waveguide Imapotoza RF Microwave Millimeter Wave Radio

RF waveguide, mawuwa nthawi zambiri amakhudza mitundu yosiyanasiyana ya ma waveguide achitsulo osasunthika komanso mafunde a pamwamba. Pakati pawo, yoyambayo imatchedwa yotsekedwa waveguide chifukwa mafunde a electromagnetic omwe amawatumizira amakhala mkati mwa chubu chachitsulo. Yotsirizirayi imatchedwanso open waveguide chifukwa mafunde a electromagnetic omwe amawongolera amakhala ozungulira mawonekedwe a waveguide. Mawayilesi amtundu woterewa amagwira ntchito yofunika kwambiri mu uvuni wa microwave, ma radar, ma satelayiti olumikizirana, ndi zida zolumikizira mawayilesi a microwave, komwe amakhala ndi udindo wolumikiza ma microwave transmitter ndi zolandila 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 mafunde a millimeter 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).
