Iyini i-antenna yophondo lwelensi
I-Antenna Yelensi Yephondoiyisakhiwo se-antenna esikhethekile esihlanganisa izici ze-lens kanye nezakhi ze-horn. Ivame ukusetshenziswa ezinhlelweni zokuxhumana kanye ne-radar kuma-microwave kanye nama-millimeter wave band. Amapharamitha ahlukahlukene e-antenna ye-horn ye-lens azokwethulwa ngokuningiliziwe ngezansi.
Inzuzo: Inzuzo yikhono le-antenna lokuguqula amandla kagesi angenayo abe amandla akhishwa imisebe. Kuma-antenna e-lens horn, inzuzo ivame ukuba yisilinganiso samandla aphezulu akhishwa imisebe ohlangothini lwe-antenna eyinhloko namandla aphezulu akhishwa imisebe e-antenna yokubhekisela (njenge-antenna yomthombo wephuzu elifanele). Inzuzo iyinkomba ebalulekile yokusebenza kwe-antenna futhi ithinta ngqo ibanga lokuxhumana kanye nokuzwela kokwamukela kwe-antenna.
Ububanzi bomsebe: Ububanzi bomsebe bubhekisela ebangeni lemisebe ye-antenna ohlangothini oluyinhloko lomsebe. Kuma-antenna e-lens-horn, ububanzi bomsebe buxhomeke ekwakhiweni kophondo kanye nesimo selensi. Ububanzi bomsebe obuncane bubonisa ukuthi i-antenna inesiqondiso esiphezulu kanye nokuqondisa.
Izinga le-side lobe: Izinga le-side lobe libhekisela ezingeni lamandla wamandla akhishwa imisebe kwezinye izikhombisi-ndlela ngaphandle kwesiqondiso se-beam maqondana ne-main beam. Uma izinga le-side lobe liphansi, kulapho amandla e-radiation e-antenna egxile khona ohlangothini lwe-main beam, enekhono elingcono lokulwa nokuphazamiseka kanye nokuqondisa.
Isilinganiso segagasi elimile: Isilinganiso segagasi elimile sibhekisela ezingeni lokufanisa i-impedance ekugcineni kokufakwa kwe-antenna. Kuma-antenna empondo yelensi, ukukalwa kwesilinganiso segagasi elimile kungasetshenziswa ukuhlola ukusebenza kokufanisa i-impedance kwe-antenna kanye nokusebenza kahle kokudluliswa kwesignali. Isilinganiso segagasi elimile eliphansi sibonisa ukufana okungcono kwe-impedance phakathi kwe-antenna nomugqa wokudlulisela.
Ububanzi bemvamisa: Ububanzi bemvamisa bubhekisela kububanzi bemvamisa lapho i-antenna ingasebenza khona ngokujwayelekile. Ama-antenna e-lens horn ngokuvamile aklanyelwe ukusetshenziswa kubhendi ethile yemvamisa, futhi ububanzi bawo bemvamisa buxhomeke ezicini zokwakhiwa kwe-antenna nezinto zokwakha.
Ibanga lokusebenza eliphumelelayo: Ibanga lokusebenza eliphumelelayo libhekisela ebangeni eliphezulu lapho i-antenna ingafinyelela khona ukusebenza okwamukelekayo kanye nekhwalithi yokudlulisela ohlelweni lokuxhumana noma lwe-radar. Le pharamitha ihlobene nezici ezifana nokwanda kwe-antenna, ububanzi be-beam kanye nezimo zemvelo.
Ubukhulu Bokwakha: Ubukhulu bokwakha bubhekisela kusayizi ongokoqobo kanye nesimo se-antenna. Kuma-antenna e-lens horn, ubukhulu bokwakha buthinta impendulo yemvamisa, ububanzi be-beamm, kanye nezici zokukhanya kwe-antenna.
Amapharamitha e-antenna yophondo lwelensi afaka phakathi ukukhuphuka, ububanzi bomsebe, izinga le-side lobe, isilinganiso samagagasi okuma, ububanzi bemvamisa, ibanga lokusebenza eliphumelelayo kanye nosayizi wokwakha. La mapharamitha acabangela izici ezifana nokusebenza kwe-antenna, isiqondiso, ukufanisa i-impedance, ukuzivumelanisa nemvamisa kanye nosayizi obonakalayo, futhi abaluleke kakhulu ekwakhiweni, ekusetshenzisweni kahle nasekusetshenzisweni kwama-antenna.
