Uma wake wangena elabhorethri yokuhlola i-EMC noma wasebenza ezinhlelweni zokuqapha i-wideband, kungenzeka ukuthi uke wahlangana ne-i-antenna ye-biconicalUma ubheka kuqala, isimo sayo esilinganayo, esifana ne-bow-tie siyabonakala—izinto ezimbili eziyindilinga zibhekene, ziphakelwa phakathi nendawo. Kodwa ngale kokubukeka kwayo okuhlukile kukhona umklamo oxazulula enye yezinselele eziyisisekelo kubunjiniyela be-antenna: ukufeza ukusebenza okulinganayo ebangeni elikhulu kakhulu lemvamisa.
Indlela Esebenza Ngayo
I-antenna ye-biconical ingacatshangwa njengokuqhubeka okuvuthayo komugqa wokudlulisela olinganiselayo. Cabanga uthatha umugqa wezintambo ezimbili bese ugoba kancane kancane ama-conductor ngaphandle aze akhe ama-cone—yilowo umqondo empeleni. Lokhu kuguquka kancane kancane kusuka kugagasi eliqondisiwe kuya kugagasi lesikhala esikhululekile yilokho okwenza i-biconical ibe yi-wideband yayo.
Ngokungafani nama-antenna aphendulayo asebenza kahle eduze kwemvamisa ethile kuphela, i-geometry ye-biconical iyivumela ukuthi ikhanye ngempumelelo kuma-octave amaningi. I-engeli yama-cone inquma i-impedance yesici, kuyilapho ubude bubeka umkhawulo wemvamisa ephansi—ama-cone amade asho imvamisa ephansi.
Izinzuzo Eziyinhloko
1. Ukusebenza kwe-Ultra-Wideband: Lesi yisici esivelele se-biconical. I-antenna eyodwa ingamboza izilinganiso zemvamisa eziyi-10:1 noma ngaphezulu—kusukela kumashumi e-MHz kuya kuma-GHz amaningana. Kumasistimu adinga ukuqapha, ukuhlola, noma ukuxhumana phakathi kwama-band amaningi, i-biconical eyodwa ingathatha indawo yama-antenna amaningana e-narrowband.
2. Iphethini Eqondiswe Kuwo Wonke Uhlangothi ku-H-Plane: Endizeni evundlile, i-biconical ikhipha imisebe efanayo kuzo zonke izinhlangothi—isici esibalulekile sezinhlelo zokusebenza ezifana nokuhlolwa kwe-EMC lapho amasignali angafika khona kunoma iyiphi i-engeli, noma izinhlelo zokusakaza nokuqapha ezidinga ukumbozwa okungu-360°.
3. Iphethini Ehambisanayo Kuyo Yonke Imvamisa: Ngokungafani namanye ama-antenna e-wideband ashintsha kakhulu iphethini yawo yemisebe ngemvamisa, ama-biconical aklanywe kahle agcina iphethini ezinzile—isici esibalulekile lapho ukuphindaphindwa kokulinganisa kubalulekile.
4. Ukwakhiwa Okulula, Okuqinile: Awekho amanethiwekhi okulungisa ayinkimbinkimbi noma izakhiwo ezibuthakathaka—amakhoni ensimbi kanye nokudla kuphela. Lokhu kwenza ama-biconical athembeke kokubili ezindaweni zelebhu kanye nokusetshenziswa kwangaphandle kwensimu.
Izicelo Ezijwayelekile
Ukuhlolwa kwe-EMC/EMI——Lokhu mhlawumbe kuyindlela evame kakhulu yokusebenzisa. Ama-Biconical angamathuluzi ajwayelekile okukhishwa kwe-radiation kanye nokuhlolwa kokuzivikela komzimba kusukela ku-30 MHz kuya ku-1 GHz nangaphezulu. Uhlobo lwawo lwe-broadband luvumela ukusheshisa kwemvamisa ngaphandle kokushintsha kwe-antenna.
Ukuqapha Ama-Spectrum——Kuma-ejensi kahulumeni kanye nabaqhubi bezokuxhumana abaqapha ama-spectrum omsakazo, ama-biconical ahlinzeka ngokumbozwa okuqhubekayo kuwo wonke ama-band amaningi, ebamba izimpawu ezingase ziphuthelwe ama-antenna e-narrowband.
Ukuxhumana kwe-Broadband——Ezinhlelweni ezidinga ukumbozwa okuqondile kuzo zonke izigaba zemvamisa—njengemisakazo yezempi yamaqhinga noma izixhumanisi zedatha ezinamabhendi amaningi—ama-biconical anikeza ikhambi le-antenna eyodwa.
Ukulinganiswa Kwamandla Ensimu——Ukuze kuhlolwe indawo kanye nokuqinisekiswa kokumbozwa, amaphethini azinzile e-biconical kanye nempendulo ye-broadband kuzenza zibe amathuluzi okulinganisa athembekile.
Izinto Okucatshangwa Ngazo Ngomklamo
Ama-biconical asebenzayo avame ukusebenzisa amakhoni ensimbi noma amapuleti angunxantathu esikhundleni sensimbi eqinile ukunciphisa isisindo kanye nomthwalo womoya. Ekufakweni kwangaphandle, ama-radome avikela esimweni sezulu. Indawo yokudla idinga ukwakheka okucophelelayo ukuze kulondolozwe ibhalansi kanye nokuhambisana kwe-impedance—okuvame ukufezwa ngama-balun noma ama-coaxial feed anama-centre conductors anomumo okhethekile.
I-antenna ye-biconical ithole indawo yayo njengethuluzi elithembekile kuma-lab e-EMC, eziteshini zokuqapha, kanye nezinhlelo zokuxhumana emhlabeni jikelele. Isixazululo sayo esihle senkinga yokumbozwa kwe-wideband—ukusebenzisa i-geometry kune-circuitry eyinkimbinkimbi—sibonisa iqiniso lobunjiniyela elijulile: ngezinye izikhathi izimo ezilula kakhulu zenza umsebenzi kangcono.
Kwa-RFMiso, sihlanganisa lo mklamo ovivinywe isikhathi eside nokukhiqiza ngokunemba kanye nezinto zesimanje ukuze sinikeze ama-antenna amabili ahlangabezana nezidingo zanamuhla ezidingakalayo—kungakhathaliseki ukuthi kuse-lab noma ngaphandle.
