Ubungakanani obuncinci beWaveguide Ukupheliswa

Ukupheliswa kobungakanani obufutshane be-waveguide yinkqubo eyenziwe ngokukodwa ye-waveguide enemilinganiselo emifutshane, esetyenziselwa ukufunxa kunye nokuchitha amandla emiqondiso ye-microwave yamandla aphantsi, ngaloo ndlela kufezekiswa ukusetyenziswa kwemiqondiso engeyomfuneko kwisekethe. Umgaqo wokupheliswa kobungakanani obufutshane be-waveguide usekwe kwiindlela ezimbini: ukubonakalisa kunye nokufunxa. Xa isignali ye-microwave idlula ukupheliswa kobungakanani obufutshane kwi-waveguide, enye yesiginali iya kubonakaliswa umva kumthombo, kwaye enye inxalenye yesiginali iya kutsalwa kukupheliswa kwe-waveguide. Ngoyilo olufanelekileyo kunye nokukhetha, ilahleko yokubonakalisa ingancitshiswa kwaye ilahleko yokufunxa inganyuswa.

Iimbonakalo:

1. Ukuba nesakhiwo esilula.
2. Ubungakanani obuqinileyo
3. Iindleko eziphantsi zokuvelisa
4.Isalathiso sokuma kwamaza sihle kakhulu.

Isicelo:

1. Ukulungiswa kweempazamo kunye novavanyo lwesekethe: Ubungakanani obuncinci be-waveguide imithwalo idla ngokusetyenziswa ekulungisweni nasekuvavanyweni kweesekethe ze-microwave. Ngokudibanisa ukupheliswa kwe-waveguide kwi-port ye-output ye-circuit ukuze ivavanywe, ukubonakaliswa komqondiso kunokuthintelwa, ngaloo ndlela kukhuselwa amacandelo esekethe kumonakalo kunye nokuqinisekisa iziphumo zovavanyo ezichanekileyo nezithembekileyo.
2. Ukulinganisa i-coefficient ye-reflection: Ngokulinganisa i-coefficient ye-reflection, ukusebenza okufanayo kwesekethe phantsi kovavanyo kunokuhlolwa. Ukupheliswa kobude obufutshane be-waveguide kungasetyenziselwa ukupheliswa kwereferensi eqhelekileyo, kwaye xa kuthelekiswa nesekethe phantsi kovavanyo, ngokulinganisa ubungakanani bomqondiso obonakalisiweyo, i-coefficient ebonakalisiweyo ingabalwa kunye nokusebenza okuhambelanayo kwesiphaluka kunokuhlalutywa.
3. Umlinganiselo wengxolo: Ubude obufutshane beMilayidi yeWaveguide nayo idlala indima ebalulekileyo kumlinganiselo wengxolo. Ngokusebenzisa iimpawu zayo zokufunxa, imiqondiso yengxolo inokusetyenziswa ngokufanelekileyo, ngaloo ndlela inciphisa ukuphazamiseka kwengxolo ngexesha lokulinganisa.
Uvavanyo lwe-antenna kunye ne-RF inkqubo: Kuvavanyo lwe-eriyali kunye ne-RF, imithwalo ye-Microwave ingasetyenziselwa ukulinganisa ukusetyenziswa kombane ongekho kwimeko apho i-eriyali ikhona. Ngokudibanisa ukupheliswa kwi-eriyali yokukhupha i-port, ukusebenza kwe-eriyali kunye nenkqubo inokuhlolwa, ilinganiswe, kwaye iphuculwe.

QualwaveIbonelela nge-VSWR ephantsi kunye nobungakanani obuncinci ukupheliswa kwe-waveguide cover frequency range 5.38 ~ 40GHz. Ukupheliswa kusetyenziswa ngokubanzi kwizicelo ezininzi.
