Ukuqedwa kwe-Waveguide yosayizi omncane
Ukuqedwa kwe-Waveguide yosayizi omncane
Ukunqanyulwa kwe-waveguide yosayizi omfushane kuyisakhiwo se-waveguide esiklanywe ngokukhethekile esinobukhulu obufushane ngokuqhathaniswa, esisetshenziselwa ukumunca futhi kuhlakaze amandla amasiginali we-microwave enamandla aphansi, ngaleyo ndlela kuzuzwe ukusetshenziswa kwamasiginali angadingekile kusekethe. Umgomo wokunqanyulwa kwe-waveguide kasayizi omfushane usekelwe ezindleleni ezimbili: ukucabangela nokumuncwa. Uma isignali ye-microwave idlula ekunqanyulweni kosayizi omfushane ku-waveguide, enye isignali izoboniswa emuva kumthombo, futhi enye ingxenye yesiginali izomuncwa ukunqanyulwa kwe-waveguide. Ngokuklama nokukhethwa okufanele, ukulahlekelwa kokubonisa kungancishiswa futhi ukulahlekelwa ukumuncwa kungakhuliswa.
Izici:
1. Ukuba nesakhiwo esilula.
2. Usayizi ohlangene
3. Izindleko zokukhiqiza eziphansi
4.Inkomba yegagasi elimile lihle kakhulu.
Isicelo:
1. Ukulungisa iphutha nokuhlola umjikelezo: Ukunqanyulwa kwe-waveguide kasayizi omfushane kuvame ukusetshenziswa ekulungiseni amaphutha nasekuhloleni amasekhethi e-microwave. Ngokuxhuma ukunqanyulwa kwe-waveguide embobeni yokuphumayo yesekethe ezohlolwa, ukubonakaliswa kwesignali kungavinjelwa, ngaleyo ndlela kuvikelwe izingxenye zesekethe emonakalweni futhi kuqinisekiswe imiphumela yokuhlola enembile nethembekile.
2. Isilinganiso se-reflection coefficient: Ngokulinganisa i-reflection coefficient, ukusebenza okufanayo kwesekethe engaphansi kokuhlolwa kungahlolwa. Ukunqanyulwa kwe-waveguide yosayizi omfushane kungasetshenziswa njengokunqanyulwa kwereferensi okujwayelekile, futhi uma kuqhathaniswa nesekhethi engaphansi kokuhlolwa, ngokulinganisa ukushuba kwesignali ebonisiwe, i-coefficient yokubonisa ingabalwa futhi ukusebenza okufanayo kwesekethe kungahlaziywa.
3. Ukulinganiswa komsindo: Ukunqanyulwa kwe-waveguide kasayizi omfushane nakho kudlala indima ebalulekile esilinganisweni somsindo. Ngokusebenzisa izici zayo zokumunca, amasignali omsindo angadliwa ngokuphumelelayo, ngaleyo ndlela kuncishiswe ukuphazamiseka komsindo phakathi nokulinganisa.
Ukuhlolwa kwesistimu ye-antenna ne-RF: Ekuhlolweni kwe-antenna nesistimu ye-RF, ukunqanyulwa kwe-waveguide kasayizi omfushane kungasetshenziswa ukulingisa ukusetshenziswa okungewona kwamandla kwemvelo lapho i-antenna itholakala khona. Ngokuxhuma ukunqanyulwa embobeni yokukhipha i-antenna, ukusebenza kwe-antenna nohlelo kungahlolwa, kulinganiswe, futhi kuthuthukiswe.
Qualwaveihlinzeka nge-VSWR ephansi kanye nokunqanyulwa kwe-waveguide kasayizi omncane kuhlanganisa ibanga lemvamisa elingu-5.38~40GHz. Ukunqanyulwa kusetshenziswa kabanzi ezinhlelweni eziningi.
