Umlando

I-antenna ye-broadband horn iyi-antenna esetshenziselwa ukuhanjiswa kwamagagasi kagesi, futhi umlando wayo ungalandelelwa emuva kuma-1930s. I-antenna ye-broadband horn yaqala ukusungulwa isazi sezinkanyezi saseMelika u-Karl Guthe Jansky ngo-1932. Wasebenzisa uthi "lophondo" oluklanywe ngokukhethekile ukuze amukele futhi akale amaza omsakazo endaweni yonke. Idizayini ye-antenna yophondo lwe-broadband igqugquzelwa uphondo lomsindo futhi imise okwecilongo ukuthuthukisa isignali eyamukelwe uthi. Emashumini ambalwa eminyaka alandelayo, izimpondo ze-broadband horn zathuthukiswa ngokuqhubekayo futhi zathuthukiswa, zaba ukuxhumana okungenantambo okubalulekile kanye nedivaysi yokubuka izinkanyezi. Namuhla, izimpondo ze-Broadband horn zisetshenziswa kakhulu kwezokuxhumana okungenantambo, izinhlelo ze-radar, izilinganiso zokuphazanyiswa komsakazo, amahhavini ama-microwave neminye imikhakha, futhi ukwakheka nokusebenza kwazo kuye kwathuthukiswa futhi kwathuthukiswa ngokuqhubekayo. Umlando wezimpondo ze-broadband kungathiwa uyingxenye ebalulekile yomlando wokuthuthukiswa kokuxhumana okungenantambo nokubhekwa kwezinkanyezi.

Isakhiwo kanye Nomgomo:

Isici esiyinhloko se-antenna yophondo lwe-broadband isakhiwo sayo esimise okophondo. Ngokuvamile iqukethe isakhiwo somhlahlandlela esime uphondo olukhula kancane kancane, lapho izinga lophondo likhula kancane kancane. Ubude nokuma kwesakhiwo somhlahlandlela kuncike ebhendini yefrikhwensi oyifunayo kanye nezidingo zokusebenza.

Umgomo wokusebenza we-antenna yophondo lwe-broadband usekelwe kusimo sophondo olukhula kancane kancane esakhiweni somhlahlandlela. Njengoba isignali idlula othini lophondo, isakhiwo somhlahlandlela sinweba kancane kancane isignali ukusuka ezindaweni ezincane ukuya ezindaweni ezinkulu. Lokhu kwandiswa kwenza i-antenna yophondo ikwazi ukukhanya kahle futhi yamukele amasignali ngebhande lefrikhwensi ebanzi ngoba amasignali amafrikhwensi ahlukene angasakazwa futhi atholakale kumasegimenti ophondo ahlukene.

Izici Nezicelo:

1. Izici ze-Broadband: Idizayini ye-antenna ye-broadband horn iyenza isebenze ngaphakathi kwebhendi yefrikhwensi ebanzi. Ingamboza amabhendi amafrikhwensi amaningi, asukela kumakhulu ama-megahertz kuya kumagigahertz ambalwa noma ngaphezulu. Lokhu kwenza ama-antenna e-wideband horn alungele izinhlelo zokusebenza ezidinga ukucutshungulwa kwamasiginali enamabhendi abanzi, njengokuxhumana, i-radar nezilinganiso ze-RF.

2. Izici zemisebe eqondile: I-antenna yophondo lwe-Broadband inezici zemisebe eyisicaba, okungukuthi, inephethini yemisebe efanayo ngaphakathi kwebanga elibanzi. Lokhu kusho ukuthi ingakhipha imisebe futhi yamukele amasiginali ngempumelelo ebangeni elibanzi lezikhombisi-ndlela ngaphandle kokuhlanekezela okubalulekile kokuqondisa.

3. Imisebe yelobe eseceleni ephansi: Izimpondo ze-Broadband horn ngokuvamile zinemisebe ephansi yelobe eseceleni, okungukuthi, ayikho imisebe eyengeziwe esobala ngaphandle kwelobe eyinhloko. Lokhu kwenza kube usizo ezinhlelweni lapho amasiginali aphazamisayo adinga ukuncishiswa noma asuswe.

4. Ukubekezelela amandla aphezulu: Izimpondo ze-Broadband horn ngokuvamile zinokubekezelela amandla aphezulu. Ikhono labo lokuphatha amasignali amandla aphezulu libenza bafanelekele izinhlelo zokusebenza zamandla aphezulu njenge-radar nezinhlelo zokuxhumana.

5. Ilula futhi inokwethenjelwa: Isakhiwo sophondo lwe-broadband antenna silula futhi kulula ukusikhiqiza nokusifaka. Ngokuvamile zenziwe ngezinto zensimbi, njenge-aluminium noma ithusi, ukuze ziqine futhi zithembeke.

Fingqa:

I-antenna ye-broadband horn wuthi olungasebenza ngaphakathi kwebhendi yefrikhwensi ebanzi. Inezici zebhendi ebanzi, izici zemisebe eyisicaba, imisebe yelobe eseceleni ephansi, amandla okuphatha amandla aphezulu, futhi ilula futhi inokwethenjelwa. Ama-antenna ophondo lwe-Broadband asetshenziswa kakhulu kwezokuxhumana, i-radar, ukukala imvamisa yomsakazo kanye nocwaningo lwesayensi neminye imikhakha ukuze kukhanye futhi kwamukelwe amasignali e-broadband.
