Ii-eriyali zeempondo ze-Broadbandzizixhobo ezisetyenziswa kwicandelo lonxibelelwano lwerediyo ukuze zidlulise kwaye zithole imiqondiso kwiindidi ezahlukeneyo zeefrikhwensi. Zenzelwe ukubonelela nge-bandwidth ebanzi kwaye zinokusebenza kwiibhendi ezininzi zeefrikhwensi. Ii-antenna zeempondo zaziwa ngokufumana kwazo okuphezulu kunye nesikhokelo, nto leyo eyenza zifaneleke kwiindlela ezahlukeneyo ezifana nonxibelelwano olungenazingcingo, iinkqubo ze-radar, kunye nonxibelelwano lwesathelayithi. Zisetyenziswa rhoqo kwiikhonkco zonxibelelwano oluya kwindawo enye, apho kufuneka khona ukudluliselwa kwedatha ekude kunye nomthamo ophezulu. Uyilo lwe-antenna yeempondo ze-broadband lubandakanya ukukhetha ngononophelo imo kunye nobukhulu besakhiwo sempondo ukuze kufezekiswe i-bandwidth ebanzi yokusebenza. Ubume bempondo bukhula kancinci kancinci ukusuka emqaleni omncinci ukuya kwindawo evulekileyo, evumela ukuhambelana okungcono kwe-impedance kunye nokusebenza kakuhle kwiindidi ezahlukeneyo zeefrikhwensi. Ii-antenna zeempondo ze-broadband zinokwakhiwa kusetyenziswa izixhobo ezahlukeneyo, ezifana nezixhobo zesinyithi okanye ze-dielectric, kuxhomekeke kwiimfuno ezithile. Ii-antenna zeempondo zesinyithi zisetyenziswa rhoqo kwizicelo zamandla aphezulu, ngelixa ii-antenna zeempondo ze-dielectric zikhethwa ngenxa yoyilo lwazo olukhaphukhaphu noluncinci. Kubalulekile ukuqaphela ukuba nangona ii-antenna zeempondo ze-broadband zinokugubungela uluhlu olubanzi lweefrikhwensi, ukusebenza kwazo kunokwahluka kwiindidi ezahlukeneyo zeefrikhwensi. Ukwanda kwee-antenna, ipateni yokukhanya, kunye nokuhambelana kwe-impedance kunokutshintsha njengoko i-frequency yokusebenza itshintsha. Ke ngoko, uhlalutyo olufanelekileyo kunye nokuqwalaselwa koyilo kubalulekile ukuqinisekisa ukusebenza kakuhle kuyo yonke i-bandwidth oyifunayo.
Ingaba isebenza kanjani:
Umgaqo wayo wokusebenza ngolu hlobo lulandelayo: I-frequency nganye ihambelana ne-resonator: Kwi-antenna ye-broadband horn, ukusebenza kwe-broadband kufezekiswa ngokusasaza imiqondiso yeefrikhwensi ezahlukeneyo kwi-resonators ezahlukeneyo. I-resonator nganye inako ukuqinisa imiqondiso ngaphakathi koluhlu oluthile lweefrikhwensi. Ulwakhiwo lwe-Horn: Ulwakhiwo lwe-horn lwe-antenna ye-broadband horn ludlala indima ebalulekileyo. Ngokuyila ngokuqiqileyo ubungakanani, imilo, ukugoba kunye nezinye iiparameter zesithethi, imiqondiso yeefrikhwensi ezahlukeneyo inokusasazwa kwaye igxile ngaphakathi kwesithethi. Ukuhanjiswa kwe-Broadband: Emva kokudlula kwisakhiwo se-horn, i-antenna ye-broadband horn inokusasaza imiqondiso kwiifrikhwensi ezininzi. Ezi signals zidluliselwa ngemitha yendawo kwaye zinokufezekisa ukuhanjiswa kwe-broadband. Inethiwekhi yokufanisa: Ukuze kuqinisekiswe ukusebenza kunye nokuhambelana kwe-impedance ye-antenna ye-broadband horn, inethiwekhi yokufanisa idla ngokongeza. Inethiwekhi yokufanisa inee-capacitors kunye nee-inductors kwaye isetyenziselwa ukulungisa i-input impedance ye-antenna ukuze ihambelane ne-impedance yomgca wokudlulisela. Uyilo kunye nomgaqo wokusebenza we-antenna ye-broadband horn ziyinkimbinkimbi, kwaye izinto ezifana noluhlu lweefrikhwensi zesignali, ukusebenza kakuhle kwemitha, kunye nokuhambelana kwe-impedance kufuneka ziqwalaselwe ngokupheleleyo. Idla ngokusetyenziswa kwiinkqubo zonxibelelwano lwe-broadband, ezifana ne-radar, unxibelelwano lwesathelayithi, unxibelelwano lwezithuthi, njl.
