I-Waveguide Twists RF Microwave Millimeter Wave Radio

I-RF waveguide, leli gama livame ukumboza izinhlobo ezahlukene zama-waveguides ensimbi engenalutho kanye nama-waveguides amagagasi angaphezulu. Phakathi kwazo, eyokuqala ibizwa ngokuthi i-closed waveguide ngoba igagasi le-electromagnetic elilidluliselayo livalelwe ngokuphelele ngaphakathi kwepayipi lensimbi. Eyokugcina ibizwa nangokuthi i-open waveguide ngoba igagasi le-electromagnetic eliliqondisayo livalelwe emkhawulweni wesakhiwo se-waveguide. Ama-waveguides anjalo e-radio frequency adlala indima ebalulekile kuma-microwave oven, ama-radar, ama-satellite okuxhumana, kanye nemishini yokuxhumanisa i-microwave radio, lapho enesibopho sokuxhuma ama-microwave transmitters kanye nama-receiver kuma-antenna awo. I-Waveguide twist ibizwa nangokuthi i-waveguide torsion joint. Ishintsha indlela ye-polarization ngokuguqula indlela yezinhlangothi ezibanzi nezincane kuzo zombili izinhlangothi, ukuze igagasi le-electromagnetic lidlule kuyo, indlela ye-polarization iyashintsha, kodwa indlela yokusabalala ihlala ingashintshi.
Uma uxhuma ama-waveguide e-millimeter wave, uma izinhlangothi ezibanzi nezincane zama-waveguide amabili ziphambene, kubalulekile ukufaka lo mhlahlandlela we-waveguide osontekile njengoshintsho. Ubude bokusonta kwe-waveguide kufanele bube yi-integer multiple engu-λ g/2, kanti ubude obufushane akufanele bube ngaphansi kuka-2 λ g (lapho i-λ g ingubude be-waveguide).
