Imbali kunye nomsebenzi wee-eriyali ze-cone horn

Imbali yee-eriyali ze-tapered horn isukela ekuqaleni kwenkulungwane yama-20. Ii-eriyali zokuqala ezifakwe kwi-tapered zasetyenziswa kwi-amplifiers kunye ne-speaker systems ukuphucula i-radiation ye-audio signals. Ngophuhliso lonxibelelwano olungenazingcingo, ii-eriyali ze-conical horn zisetyenziswa ngokuthe ngcembe kwiindawo zikanomathotholo kunye ne-microwave. Izibonelelo zayo kwimitha ye-electromagnetic wave kunye nokwamkelwa kuyenza ibe sisakhiwo esibalulekileyo se-eriyali. Emva kweminyaka yee-1950s, ngophuhliso olukhawulezayo lwetekhnoloji yonxibelelwano lwe-microwave, i-eriyali ze-conical horn zaqala ukusetyenziswa kakhulu kwimimandla yasemkhosini neyasekuhlaleni. Isetyenziswa kwizicelo ezifana neenkqubo zeradar, iinkqubo zonxibelelwano, unxibelelwano ngesathelayithi, imilinganiselo yerediyo kunye noluhlu lwee-eriyali. Uyilo kunye nokulungelelaniswa kwee-eriyali ze-tapered horn nazo zifumene uthotho lophando kunye nophuculo. Ukususela kuhlalutyo lokuqala lwethiyori ukuya ekuqalisweni kokulinganisa kwamanani kunye ne-algorithms yokuphucula, ukusebenza kwee-antenna ze-tapered horn iyaqhubeka nokuphucula. Namhlanje, i-eriyali ye-eriyali ene-tapered iye yaba sisakhiwo esiqhelekileyo kunye nesisiseko se-eriyali esisetyenziswa ngokubanzi kunxibelelwano olungenazingcingo kunye nobuchwepheshe be-microwave.
Isebenza ngokukhokelela amaza ombane ukusuka kumazibuko amancinane ukuya kumazibuko amakhulu ukuze kuzuzwe inzuzo ephezulu kunye nokuphendula okuphindaphindwayo. Xa i-electromagnetic wave ingena kwizibuko elincinane le-eriyali yophondo olune tapered ukusuka kumgca wothumelo (ofana nentambo ye-coaxial), iliza lombane liqala ukwanda kumphezulu wesakhiwo esithe thaca. Njengoko i-conical structure isanda ngokuthe ngcembe, amaza e-electromagnetic asasazeka ngokuthe ngcembe, esenza indawo enkulu yemitha. Oku kwandiswa kwejiyometri kubangela ukuba amaza ombane aphume kwizibuko elikhulu le-eriyali yophondo oluthenjiweyo. Ngenxa yobume obukhethekileyo besakhiwo sekhowuni, ukwahluka komqadi wamaza e-electromagnetic kwindawo yeradiation kuncinci, oko kunika inzuzo ephezulu. Umgaqo osebenzayo we-eriyali yophondo oluyi-conical uxhomekeke ekubonakalisweni, ukuchaswa kunye nokuphazamiseka kwamaza ombane we-electromagnetic ngaphakathi kwesakhiwo se-conical. Ezi nkqubo zivumela amaza ombane ukuba agxile kwaye asasazeke, ewavumela ukuba aphume ngokufanelekileyo. Ngamafutshane, umgaqo osebenzayo we-eriyali yophondo oluyiconical kukukhokela amaza ombane ukusuka kwizibuko elincinane ukuya kwizibuko elikhulu, ukufikelela kwimitha yelanga yombane kunye nenzuzo ephezulu ngesakhiwo esikhethekileyo sejometri. Oku kwenza ukuba i-eriyali ye-tapered i-eriyali ibe luhlobo olubalulekileyo lwe-eriyali kunxibelelwano olungenazingcingo kunye nosetyenziso lwe-microwave.
