Waveguide Sotha RF Microwave Millimeter Wave Radio

RF waveguide, hangata lentsoe le akaretsa mefuta e fapaneng ea maqhubu a tšepe a se nang letho le maqhubu a maqhubu a holim'a metsi. Har'a tsona, ea pele e bitsoa "waveguide" e koetsoeng hobane leqhubu la motlakase leo le le fetisang le koaletsoe ka ho feletseng ka har'a tube ea tšepe. Ea morao-rao e boetse e bitsoa open waveguide hobane leqhubu la motlakase leo e le tataisang le lekanyelitsoe moeling oa sebopeho sa waveguide. Li-waveguide tse joalo tsa maqhubu a seea-le-moea li phetha karolo ea bohlokoa liontong tsa microwave, liradara, lisathelaete tsa puisano, le thepa ea khokahanyo ea radio ea microwave, moo li ikarabellang bakeng sa ho hokahanya li-transmitters le li-receiver tsa microwave le manakana a tsona. Waveguide twist e boetse e bitsoa waveguide torsion joint. E fetola tataiso ea polarization ka ho khutlisetsa tataiso ea mahlakoreng a pharaletseng le a moqotetsane lipheletsong tse peli, e le hore leqhubu la motlakase le fete ho eona, tataiso ea polarization e fetoha, empa tataiso ea ho phatlalatsoa e lula e sa fetohe.
Ha ho hokeloa li-waveguide tsa millimeter wave, haeba mahlakore a sephara le a moqotetsane a li-waveguide tse peli a fapane, hoa hlokahala ho kenya leqhubu lena le sothehileng joalo ka phetoho. Bolelele ba waveguide twist e lokela ho ba palo e felletseng ea makhetlo a mangata a λ g/2, 'me bolelele bo khuts'oane bo se be ka tlase ho 2 λ g (moo λ g e leng bolelele ba maqhubu a waveguide).
