Ukupheliswa kweWaveguide yobukhulu obuncinci

Ukupheliswa kwe-waveguide yobukhulu obufutshane sisakhiwo se-waveguide esiyilwe ngokukodwa esinemilinganiselo emifutshane, esisetyenziselwa ukufunxa nokususa amandla emiqondiso ye-microwave enamandla aphantsi, ngaloo ndlela kufezekiswa ukusetyenziswa kwemiqondiso engafunekiyo kwisekethe. Umgaqo wokupheliswa kwe-waveguide yobukhulu obufutshane usekelwe kwiindlela ezimbini: ukubonakalisa kunye nokufunxa. Xa isignali ye-microwave idlula ekuphelisweni kobukhulu obufutshane kwi-waveguide, enye yesignali iya kubonakaliswa ibuyele kumthombo, kwaye enye inxalenye yesignali iya kufunxwa kukupheliswa kwe-waveguide. Ngoyilo olufanelekileyo kunye nokukhetha, ilahleko yokubonakalisa ingancitshiswa kwaye ilahleko yokungenisa ingandiswa.

Iimbonakalo:

1. Ukuba nesakhiwo esilula.
2. Ubungakanani obuncinci
3. Iindleko eziphantsi zokuvelisa
4. Isalathisi samaza amiyo sigqibelele kakhulu.

Isicelo:

1. Ukulungiswa nokuvavanywa kwesekethe: Imithwalo ye-waveguide encinci idla ngokusetyenziswa ekulungisweni nasekuvavanyweni kweesekethe ze-microwave. Ngokuqhagamshela ukuphela kwe-waveguide kwi-output port yesekethe eza kuvavanywa, ukubonakaliswa kwesignali kunokuthintelwa, ngaloo ndlela kukhuselwe izinto zesekethe ekonakalisweni kwaye kuqinisekiswe iziphumo zovavanyo ezichanekileyo nezithembekileyo.
2. Ukulinganiswa kwe-coefficient yokubonakalisa: Ngokulinganisa i-coefficient yokubonakalisa, ukusebenza okulinganayo kwesekethe evavanyiweyo kunokuvavanywa. Ukuphela kwe-waveguide yobude obufutshane kunokusetyenziswa njengee-standard reference terms, kwaye xa kuthelekiswa nesekethe evavanyiweyo, ngokulinganisa ubunzulu besignali ebonakalisiweyo, i-coefficient yokubonakalisa inokubalwa kwaye ukusebenza okulinganayo kwesekethe kunokuhlalutywa.
3. Ukulinganiswa kwengxolo: I-Short Long Waveguide Imithwalo ikwadlala indima ebalulekileyo ekulinganisweni kwengxolo. Ngokusebenzisa iimpawu zayo zokufunxa, imiqondiso yengxolo ingasetyenziswa ngokufanelekileyo, ngaloo ndlela kunciphisa ukuphazamiseka kwengxolo ngexesha lokulinganisa.
Uvavanyo lwenkqubo ye-Antena kunye ne-RF: Kuvavanyo lwenkqubo ye-antenna kunye ne-RF, imithwalo ye-microwave ingasetyenziselwa ukulinganisa ukusetyenziswa kwamandla okusingqongileyo apho i-antenna ikhoyo. Ngokuqhagamshela ukuphela kwe-antenna kwi-port ye-output ye-antenna, ukusebenza kwe-antenna kunye nenkqubo kunokuvavanywa, kulinganiswe, kwaye kuphuculwe.

I-QualwaveIbonelela nge-VSWR ephantsi kwaye ii-waveguide terminals ezincinci zigubungela uluhlu lwamaza angama-5.38 ~ 40GHz. Ii-terminals zisetyenziswa kakhulu kwiindawo ezininzi zokusebenza.
