Kunesidingo esandayo sezinhlelo zokuxhumana nge-broadband ezinhlotsheni ezahlukahlukene zamapulatifomu angomahamba nendlwana, isibonelo, imikhumbi yasolwandle, izimoto zomhlaba kanye nezindiza. Ngayinye yalezi zinsizakusebenza zine-radar eyodwa noma amaningi, futhi i-radar ngayinye inohlelo lwe-antenna oluhlukile, oluqhutshwa ngomshini ku-azimuth nokuphakama. Ngohlelo lokuxhumana lwesathelayithi olubanzi lwe-satellite olune-antenna efakwe emotweni, i-antenna isetshenziselwa ukusiza ukwakha ukuxhumana kokuxhumana nesathelayithi esuselwa endaweni ku-geosynchronous orbit. I-antenna yakha ingxenye yetheminali yezokuxhumana ethwalwa yimoto. Ama-Antena anekhono lokulandela ngomkhondo, ngokunemba okuphezulu, iziphuphutheki zokuxhumana ezivela kuzingxenyekazi ezihambayo ezifana nezindiza, imikhumbi nezimoto zomhlaba, phakathi kokunye, ukukhulisa isilinganiso sedatha, ukwenza ngcono ukusebenza kwe-downlink nokudluliswa kwe-uplink, kanye / noma ukuvimbela ukuphazamiseka iziphuphutheki ezizungeza eduze kwesathelayithi eqondisiwe. Ama-antenna anjalo avumela amapulatifomu okuxhumana ngesathelayithi ahamba phambili aneziqubulo eziphakeme kakhulu, njengezindiza nezimoto zomhlaba ukuthola amasiginali avela kanye / noma ukudlulisa amasignali kumasathelayithi afana neziphuphutheki ze-geostationary.
I-antenna ejikelezayo yakha isisekelo kanye nesisekelo esijikelezayo esisekela okungenani isibonakaliso esisodwa se-antenna kanye neyunithi yokudlulisa / yokwamukela i-RF, isisekelo kanye nesisekelo esijikelezayo esifakwe ngokufana, inhlanganisela ejikelezayo ebekwe ukuvumela ukudluliswa kwezimpawu zamaza omsakazo (RF) phakathi isisekelo esijikelezayo nesisekelo ngesikhathi sokunyakaza kokujikeleza kwesihlobo esisodwa kuya kwesinye kuzungeze i-eksisi yokuzungezisa, isifaki khodi sokulandela ukunyakaza kokujikeleza, iringi yokuhambisa esetshenziselwe ukumisa iphrofayili emile yokuhlangana okujikelezayo phakathi kwensika nokujikeleza base ukuze kugcinwe ukuxhumana kogesi lapho phakathi kokunyakaza kokujikeleza, kanye nokuthwala okuyindilinga okumiswe kahle ukuhlanganisa isifaki khodi kanye namasongo okushibilika kobuningi azungeze i-eksisi yokujikeleza nokucindezela ukunyakaza kokujikeleza. Ijoyini elijikelezayo, iyunithi yendandatho eshelelayo kanye ne-annular bearing kugxilile nokuhlangana okujikelezayo, isifaki khodi, nomthamo wonyaka osendizeni ejwayelekile evundlile.
Isiliphu sendandatho nebhulashi lisetshenziselwa ukudlulisa ukulawulwa kwamandla kagesi kanye nesiginali yesimo kuye nokubuya kumasekethe wokuphakama ngenkathi i-antenna ijikeleza ku-azimuth. Ukusetshenziswa kwendandatho eshelelayo ohlelweni lwe-antenna kuyefana neyunithi yokutsheka. Idivayisi yokutsheka enesilayidi esididiyelwe ivame ukusetshenziselwa ukunikeza ukubekwa kwesikhathi okunembile kwe-antenna nakho. Amanye amadivayisi we-pan-tilt wokusebenza aphezulu anikezela i-interface ye-Ethernet / web ehlanganisiwe, futhi indandatho eshibhile yokuhambisa iyadingeka ngokudluliswa kwe-Ethernet.
Izinhlelo ezihlukile ze-antenna zidinga namasongo ahlukahlukene okushelela futhi. Ngokuvamile, iringi yesilayiti semvamisa ephezulu, iringi yokuma kobumba ngoqwembe (iringi yokuphakama okuphansi) futhi ngendandatho yesiliphu esibholayo kuvame ukusungulwa ezinhlelweni ze-antenna. Eminyakeni yamuva nje, i-radar yasolwandle ene-antenna ejikelezayo iye yafuna ngokushesha, eziningi zazo zidinga ukuxhumana kwe-Ethernet. Izindandatho ze-AOOD Ethernet slip zivumela ukuxhumeka okungu-1000/100 base T Ethernet kusuka kokulungisiwe kuya kupulatifomu ejikelezayo kanye nezinguquko ezingaphezu kwezigidi ezingama-60 zokuphila konke.
