Izindaba - Qonda izimiso zokuklama kanye nezici zokusebenza kwama-antenna amabili

I-Biconical Antenna iyi-antenna ekhethekile ye-wide-band enesakhiwo sayo sakhiwe ngamakhoni amabili ensimbi ahambisanayo axhunywe phansi futhi axhunywe emthonjeni wesignali noma kumukeli ngenethiwekhi yokunquma. Ama-antenna e-biconical asetshenziswa kabanzi ekuhlolweni kokuhambisana kwe-electromagnetic (EMC), ukuxhumana okungenantambo kanye nezinhlelo ze-radar. Umgomo osebenzayo we-antenna ye-biconical ukusebenzisa izici zokukhanya kanye nemisebe yamagagasi kagesi kuma-conductor ensimbi. Lapho igagasi le-electromagnetic lingena kwi-antenna ye-biconical, lizobonakala izikhathi eziningi ebusweni bekhoni, kwakha umphumela wokusabalalisa we-multipath. Lokhu kusakazwa kwe-multipath kubangela ukuthi i-antenna ikhiqize iphethini yemisebe efanayo ngendlela yokukhanya. Isici esiyinhloko sama-antenna e-biconical ukusebenza kwawo kwe-wide-band. Ingasebenza ngaphezu kwebanga elikhulu lemvamisa, ngokuvamile ihlanganisa amakhulu ambalwa e-megahertz kuya kuma-gigahertz amaningana. Lesi sici senza ama-antenna e-biconical asetshenziswe kabanzi ekuhlolweni nasekulinganisweni kokuxhumana okungenantambo kwe-wide-band, kanye nokuhlolwa kwe-EMC kwemishini ebangeni elihlukene lemvamisa. Ngaphezu kwalokho, isakhiwo se-antenna ye-biconical silula futhi kulula ukusenza, ukuyifaka nokusebenzisa. Kodwa-ke, ama-antenna e-biconical nawo anemikhawulo ethile. Okokuqala, inzuzo ye-antenna iphansi kakhulu ngenxa yokusebenza kwayo kwe-broadband. Okwesibili, njengoba ukwakheka nokukhiqizwa kwama-antenna kudinga ukucabangela ububanzi bemvamisa nezinye izidingo, kungase kube nezici ze-antenna ezahlukene kuma-frequency band athile. Ngakho-ke, kubalulekile ukukhetha i-antenna ye-biconical efanele ngokwezidingo ezithile kuhlelo lokusebenza. Ngokuvamile, i-antenna ye-biconical iyi-antenna ekhethekile esebenza nge-wide-band futhi ifanele ukuxhumana okungenantambo kwe-wide-band, ukuhlolwa kwe-EMC kanye nokulinganisa. Inezinzuzo zesakhiwo esilula, ukukhiqizwa okulula kanye nokusetshenziswa, kodwa kudingeka kuqashelwe ukukhethwa kwe-gain kanye nezici ze-frequency band ezahlukene.
