Izindaba - Qonda izimiso zokuklama nezici zokusebenza zama-antenna amabili

I-Biconical Antenna iyi-antenna ekhethekile enebhendi ebanzi eyakhiwe ngamakhoni ensimbi amabili alinganayo axhumeke phansi futhi axhunywe kumthombo wesignali noma umamukeli ngenethiwekhi yokunquma. Ama-antenna angama-Biconical asetshenziswa kabanzi ekuhlolweni kokuhambisana kwe-electromagnetic (EMC), ukuxhumana okungenantambo kanye nezinhlelo ze-radar. Umgomo wokusebenza we-biconical antenna ukusebenzisa izici zokubonisa kanye nemisebe yamagagasi kagesi kumakhondakta ensimbi. Uma igagasi kazibuthe lingena ku-antenna e-biconical, lizobonakala izikhathi eziningi ebusweni bekhoni, kwenze umphumela wokusakazwa kwe-multipath. Lokhu kusakazwa kwe-multipath kubangela ukuthi i-antenna ikhiqize iphethini yemisebe efanayo ngokuqhathaniswa lapho ibheke khona emisebeni. Isici esiyinhloko sama-antenna angama-biconical ukusebenza kwawo kwebhande elibanzi. Ingasebenza ebangeni elikhulu lefrikhwensi, ivamise ukumboza amakhulu ambalwa ama-megahertz kuya kumagigahertz ambalwa. Lesi sici senza ama-antenna angama-biconical asetshenziswe kabanzi ekuhloleni nasekukaleni ukuxhumana okungenantambo kwe-wide-band, kanye nokuhlolwa kwe-EMC kwemishini kumafrikhwensi ahlukene. Ngaphezu kwalokho, ukwakheka kwe-biconical antenna kulula futhi kulula ukwenza, ukuyifaka nokusebenzisa. Kodwa-ke, ama-antenna angama-biconical nawo anemikhawulo ethile. Okokuqala, inzuzo ye-antenna iphansi kakhulu ngenxa yokusebenza kwayo kwe-broadband. Okwesibili, njengoba ukuklanywa nokwakhiwa kwezinti kudinga ukucabangela ububanzi befrikhwensi nezinye izidingo, kungase kube nezici ezihlukile zothi kumabhendi athile efrikhwensi. Ngakho-ke, kuyadingeka ukukhetha i-antenna efanele ye-biconical ngokuya ngezidingo ezithile kuhlelo lokusebenza. Ngokuvamile, i-biconical antenna iyi-antenna ekhethekile esebenza ngebhande elibanzi futhi ifanele ukuxhumana okungenantambo kwe-wide-band, ukuhlolwa kwe-EMC nokulinganisa. Inezinzuzo zesakhiwo esilula, ukukhiqiza nokusetshenziswa okulula, kodwa kudinga ukunakwa ekukhetheni inzuzo kanye nezici zebhendi ezihlukene.
