Yintoni i-antenna yelensi yophondo
I-Antenna yeLens Hornsisakhiwo esikhethekileyo se-antenna esidibanisa iimpawu zeelensi kunye nezinto ze-horn. Sisetyenziswa kakhulu kwiinkqubo zonxibelelwano kunye ne-radar kwiibhendi zamaza ze-microwave kunye ne-millimeter. Iiparameter ezahlukeneyo ze-antenna ye-horn yelensi ziya kwaziswa ngokweenkcukacha ngezantsi.
Inzuzo: Inzuzo kukukwazi kwe-antenna ukuguqula amandla ombane angenayo abe ngamandla akhutshwayo. Kwii-antenna ze-lens horn, inzuzo idla ngokuba ngumlinganiselo wamandla aphezulu akhutshwayo kwicala le-antenna ephambili ukuya kumandla aphezulu akhutshwayo e-antenna yesalathiso (njenge-antenna yomthombo wenqaku elifanelekileyo). Inzuzo luphawu olubalulekileyo lokusebenza kwe-antenna kwaye ichaphazela ngokuthe ngqo umgama wonxibelelwano kunye nobuntununtunu bokufumana i-antenna.
Ububanzi bemitha: Ububanzi bemitha bubhekisa kuluhlu lwemitha ye-antenna kwicala eliphambili lemitha. Kwii-antenna ze-lens-horn, ububanzi bemitha buxhomekeke kuyilo lwe-horn kunye nokuma kwelensi. Ububanzi bemitha obuncinci bubonisa ukuba i-antenna inendlela ephezulu kunye nendlela ephezulu.
Inqanaba le-side lobe: Inqanaba le-side lobe libhekisa kwinqanaba lamandla ombane okhutshwe kwiindlela ezingezizo eze-beam xa kuthelekiswa nomqadi oyintloko. Okukhona inqanaba le-side lobe liphantsi, kokukhona amandla ombane e-antenna egxile ngakumbi kwicala le-main beam, enentsebenzo engcono yokulwa nokuphazamiseka kunye nokuqondisa.
Umlinganiselo wamaza amileyo: Umlinganiselo wamaza amileyo ubhekisa kwinqanaba lokuhambelana kwe-impedance kwisiphelo sokufaka se-antenna. Kwii-antenna ze-lens horn, ukulinganiswa komlinganiselo wamaza amileyo kungasetyenziselwa ukuvavanya ukusebenza kokuhambelana kwe-impedance ye-antenna kunye nokusebenza kakuhle kokudluliselwa kwesignali. Umlinganiselo wamaza asezantsi amileyo ubonisa ukuhambelana okungcono kwe-impedance phakathi kwe-antenna kunye nomgca wokudluliselwa.
Uluhlu lweefrikhwensi: Uluhlu lweefrikhwensi lubhekisa kuluhlu lweefrikhwensi apho i-antenna inokusebenza khona ngokuqhelekileyo. Ii-antenna ze-lens horn zihlala zenzelwe ukusetyenziswa kwibhendi ethile yeefrikhwensi, kwaye uluhlu lwazo lweefrikhwensi luxhomekeke kwiimpawu zokwakhiwa kwe-antenna kunye nezixhobo.
Umgama osebenzayo wokusebenza: Umgama osebenzayo wokusebenza ubhekisa kumgama ophezulu apho i-antenna inokufikelela khona ukusebenza okwamkelekileyo kunye nomgangatho wokudluliselwa kwinkqubo yonxibelelwano okanye yeradar. Le parameter inxulumene nezinto ezinje ngokufumana i-antenna, ububanzi bemitha kunye neemeko zokusingqongileyo.
Ubukhulu boKwakha: Ubukhulu bokwakha bubhekisela kubukhulu bomzimba kunye nokuma kwe-antenna. Kwii-antenna ze-lens horn, ubukhulu bokwakha buchaphazela impendulo ye-frequency, ububanzi be-beamm, kunye neempawu zemitha ye-antenna.
Iiparameter ze-antenna ye-lens horn ziquka i-gain, ububanzi be-beam, i-side lobe level, i-standing wave ratio, i-frequency range, umgama osebenzayo wokusebenza kunye nobukhulu bokwakhiwa. Ezi parameter ziqwalasela izinto ezifana nokusebenza kwe-antenna, i-directivity, i-impedance matching, i-frequency adjustability kunye nobukhulu bomzimba, kwaye zibaluleke kakhulu kuyilo, ukulungiswa kunye nokusetyenziswa kwe-antenna.
