Ukuba wakha wangena kwi-EMC test lab okanye wasebenza kwiinkqubo zokubeka esweni i-wideband, kusenokwenzeka ukuba ukhe wadibana ne-i-antenna ye-biconical. Xa uyijonga okokuqala, imilo yayo efana ne-bow-tie iyabonakala—izinto ezimbini ezijonge enye kwenye, zijongwe embindini. Kodwa ngaphaya kwembonakalo yayo eyahlukileyo kukho uyilo olusombulula enye yeengxaki ezibalulekileyo kubunjineli be-antenna: ukufezekisa ukusebenza okuzinzileyo kuluhlu olubanzi kakhulu lwamaza.
Ingaba isebenza kanjani
I-antenna ye-biconical ingacingelwa njengokuqhubeka okuvuthayo komgca wokudlulisela olinganiselayo. Khawuthelekelele uthatha umgca weentambo ezimbini uze ugobe kancinci kancinci ii-conductors ngaphandle de zenze iikhowuni—yiloo nto ke leyo. Olu tshintsho luhamba kancinci kancinci ukusuka kwi-guided wave ukuya kwi-free-space wave yiyo eyenza i-biconical ibe yi-wideband yayo.
Ngokungafaniyo nee-antenna eziphendulayo ezisebenza ngokufanelekileyo kufutshane ne-frequency ethile, i-geometry ye-biconical ivumela ukuba ikhanye ngokufanelekileyo kwii-octaves ezininzi. I-engile yee-cones imisela i-characteristic impedance, ngelixa ubude bubeka umda we-low-frequency—ii-cones ezinde zithetha ii-frequency eziphantsi.
Iingenelo eziphambili
1. Ukusebenza kwe-Ultra-Wideband: Olu luphawu olubalaseleyo lwe-biconical. I-antenna enye inokugubungela umlinganiselo wamaza okuphindaphinda we-10:1 okanye ngaphezulu—ukusuka kumashumi e-MHz ukuya kwi-GHz ezininzi. Kwiinkqubo ezifuna ukujonga, ukuvavanya, okanye ukunxibelelana kwiibhendi ezininzi, i-biconical enye inokuthatha indawo yee-antenna ezininzi ze-narrowband.
2. Ipateni ye-Omnidirectional kwi-H-Plane: Kwiplane ethe tye, i-biconical ikhanya ngokufanayo kuzo zonke iindlela—uphawu olubalulekileyo kwizicelo ezinje ngovavanyo lwe-EMC apho imiqondiso inokufika khona nakweyiphi na i-engile, okanye kwiinkqubo zokusasaza nokubeka iliso ezifuna ukugqunywa yi-360°.
3. Ipateni Ehambelanayo Kuyo Yonke Imvamisa: Ngokungafaniyo nezinye ii-antenna ze-wideband ezitshintsha kakhulu ipateni yazo yemitha ngokuphindaphindiweyo, ii-biconicals eziyilwe kakuhle zigcina ipateni ezinzileyo—uphawu oluxabisekileyo xa ukulinganisa ukuphindaphindwa kubalulekile.
4. Ulwakhiwo olulula noluqinileyo: Akukho nethiwekhi zokulungisa ezintsonkothileyo okanye izakhiwo ezibuthathaka—kukho nje iikhowuni zesinyithi kunye nokutya. Oku kwenza ii-biconicals zithembeke kuzo zombini iindawo zelebhu kunye nokusasazwa kwangaphandle kwentsimi.
Izicelo eziqhelekileyo
Uvavanyo lwe-EMC/EMI——Mhlawumbi olu lolona setyenziso luqhelekileyo. IiBiconicals zizixhobo eziqhelekileyo zokukhupha umbane ngemitha kunye novavanyo lokuzikhusela komzimba ukusuka kwi-30 MHz ukuya kwi-1 GHz nangaphezulu. Uhlobo lwazo lwe-broadband luvumela ukukhutshelwa ngokukhawuleza kwamaza ngaphandle kotshintsho lwe-antenna.
Ukubeka iliso kwiSpectrum——Kwiiarhente zikarhulumente kunye nabaqhubi beefowuni abajonga ispectrum yerediyo, ii-biconicals zibonelela ngokugubungela okuqhubekayo kwiibhendi ezininzi, zibamba imiqondiso enokuthi i-antennas ye-narrowband ingayiboni.
Unxibelelwano lweBroadband——Kwiinkqubo ezifuna ukugubungela yonke indawo kwiireyithingi ezibanzi—ezifana neeradiyo zomkhosi ezisebenzisa amaqhinga okanye iikhonkco zedatha ezinamabhendi amaninzi—ii-biconicals zibonelela ngesisombululo se-antenna enye.
Ukulinganiswa kwamandla entsimi——Kwiiphando zesiza kunye nokuqinisekiswa kokugubungela, iipateni ezizinzileyo ze-biconicals kunye nempendulo ye-broadband zenza zibe zizixhobo zokulinganisa ezinokuthenjwa.
Izinto eziqwalaselwayo kuYilo
Ii-biconicals ezisebenzayo zihlala zisebenzisa ii-wire cones okanye iipleyiti eziziingxantathu endaweni yesinyithi esiqinileyo ukunciphisa ubunzima kunye nomthwalo womoya. Kwiifekthi zangaphandle, ii-radomes zikhusela kwimozulu. Indawo yokutya ifuna uyilo olucokisekileyo ukugcina ibhalansi kunye nokuhambelana kwe-impedance—idla ngokufezekiswa ngee-baluns okanye ii-coaxial feeds ezinee-center conductors ezimile ngokukodwa.
I-antenna ye-biconical ifumene indawo yayo njengesixhobo esithembekileyo kwiilebhu ze-EMC, kwizitishi zokubeka esweni, nakwiinkqubo zonxibelelwano kwihlabathi liphela. Isisombululo sayo esihle kwingxaki yokugubungela i-wideband—ukusebenzisa i-geometry endaweni yesekethe enzima—sibonisa inyani yobunjineli enzulu: ngamanye amaxesha iimilo ezilula zenza umsebenzi kakuhle.
Apha kwi-RFMiso, sidibanisa olu yilo luvavanyiweyo ixesha elide kunye nokuveliswa ngokuchanekileyo kunye nezixhobo zanamhlanje ukuze sinike ii-antenna ezimbini ezihlangabezana neemfuno ezifunekayo zanamhlanje—nokuba kusezilabhoratri okanye ngaphandle.
