Ama-antenna e-biconical asetshenziswa kabanzi ekuhlolweni nasekulinganisweni kwe-RF lapho ukusebenza kwe-broadband, ukumbozwa kwe-azimuth ebanzi, kanye nokuhlanganiswa kwesistimu eguquguqukayo kubalulekile. Ngamamodeli aklanyelwe izinhlelo zokusebenza ezisukela kumaza aphansi e-RF kuya kuma-microwave, ama-millimeter-wave, kanye nama-sub-THz band akhethiwe,Uchungechunge lwe-RF MISO Biconical Antennainikeza onjiniyela izinketho eziningi ezahlukene zemvamisa, i-polarization, kanye nezidingo ze-interface.
Esikhundleni sokuthembela ku-antenna eyodwa ukumboza lonke ububanzi, uchungechunge lwe-RF MISO luhlanganisa amamodeli amaningi ambozaamabhendi emvamisa akhethiwe kusukela ku-0.02 GHz kuya ku-303 GHzLokhu kunikeza onjiniyela ukuguquguquka kokukhetha i-antenna ngokuya ngebhendi yokusebenza yangempela kanye nendawo yokulinganisa.
Ukumbozwa kwe-Broadband kwezinhlelo zokusebenza ezahlukene ze-RF
Ububanzi bemvamisa ngokuvamile yibo okufanele ucabangele kuqala lapho ukhetha i-antenna ye-biconical. Uchungechunge lwe-RF MISO luhlanganisa amamodeli ahlanganisa izinhlobo ezahlukene zamabhendi okusebenza, kusukela ezinhlelweni ze-broadband ezisebenzisa imvamisa ephansi kuya kuzinhlelo zokusebenza ze-millimeter-wave ephezulu kanye ne-sub-THz.
Isibonelo, i-RM-BCA0023-2isebenza kusukela0.02 kuya ku-3 GHz, kuyilapho amamodeli afana ne-RM-BCA120-2futhiRM-BCA245-3khulisa ukusebenza ku-20 GHzfuthi45 GHz, ngokulandelana.
Ngezinhlelo zokusebenza ezivame kakhulu,RM-BCA10110-4 izembozo10 kuya ku-110 GHz, ngenkathiRM-BCA300-3yenzelwe ukusebenza kusukela297 kuya ku-303 GHz.
Lokhu kukhethwa kwemodeli okubanzi kuvumela onjiniyela ukuthi bakhethe ububanzi bemvamisa obuhambisana nokulinganiswa okuqondiwe noma uhlelo lwe-RF esikhundleni sokuphazamisa ukusebenza nge-antenna engafanele.
Ukumbozwa Okubanzi kwe-Azimuth
Isici esibalulekile somndeni we-RF MISO biconical antenna ukumbozwa kwe-azimuth ebanzi.
Kuye ngemodeli, la ma-antenna afaneleka ezinhlelweni ze-RF lapho amasignali kudingeka adluliselwe noma amukelwe ngebanga elibanzi elivundlile le-angular. Lokhu kwenza uchungechunge lube wusizo ekuqapheni amasignali e-broadband, ekuqapheni, ekutholeni isiqondiso, ekuhloleni, nasezindaweni ezahlukene zokulinganisa i-RF.
Emalabhorethri e-antenna, ama-antenna e-biconical angasetshenziswa futhi ekuqhathaniseni inzuzo, ukulinganisa iphethini yemisebe, kanye nokuqinisekiswa kwegumbi.
Ukucushwa Okuhlukahlukene Kokuhlukaniswa
Izinhlelo ezahlukene ze-RF zingadinga izici ezahlukene ze-polarization.
Uchungechunge lwe-RF MISO Biconical Antenna luhlanganisa amamodeli ane-ukuhlukaniswa okuqondile okuqondile, ukuhlukaniswa okuqondile okungu-45°, ukuhlukaniswa okujwayelekile okuqondile, kanye nokulungiselelwa okukhethiwe okuhlukaniswe ngokuzungeza.
Isibonelo, amamodeli amaningana e-broadband asebenzisa i-polarization eqondile noma engu-45° slant linear, kuyilaphoRM-BCA3537-3, esebenza kusukela35 kuya ku-37 GHz, inikeza ukucushwa kwe-polarization okuyisiyingi esikabili.
Lolu hlu lwezinketho ze-polarization lunikeza onjiniyela ukuguquguquka okwengeziwe lapho befanisa i-antenna nezidingo ze-polarization zesistimu ye-RF ezungezile.
Izixhumi ze-RF eziguquguqukayo
Ukuhlanganiswa kwesistimu kuba yinto ebaluleke kakhulu njengoba imvamisa yokusebenza ikhula.
Kuwo wonke uchungechunge, i-RF MISO inikeza izinhlobo ezahlukene ze-coaxial kanye ne-waveguide interfaces, okuhlanganisa:
- Owesifazane we-SMA
- Owesifazane Owesifazane
- Owesifazane ongu-2.92 mm
- Owesifazane ongu-2.4 mm
- Owesifazane ongu-1.0 mm
- Izixhumi ze-waveguide ezikhethiwe
Ekugcineni kochungechunge,RM-BCA300-3isebenzisaUmhlahlandlela wamagagasi we-WR3 one-flange ye-UG-387, enikeza isikhombimsebenzisi esifanele ububanzi bayo bokusebenza obungu-297–303 GHz.
Ukutholakala kwezindawo ezahlukene zokuxhumanisa i-RF kusiza onjiniyela ukuhlanganisa i-antenna nezinsimbi zokuhlola, iziphetho zangaphambili ze-RF, izinto zokulinganisa, nezinye izingxenye zesistimu.
Yakhelwe Ukuhlolwa Nokulinganiswa kwe-RF
Ama-antenna e-biconical angadlala indima ehlukene kuye ngokuthi ibhendi yemvamisa kanye nokucushwa kwesistimu.
Izicelo ezijwayelekile ze-RF MISO Biconical Antenna Series zifaka ukuhlolwa kwe-EMC, okuhlanganisa ukukhishwa kwe-radiation kanye nokulinganiswa kokuzivikela komzimba okubangelwa imisebe; ukulinganiswa kwe-antenna kanye nokuqhathaniswa kokuzuza; ukulinganiswa kwephethini ye-radiation kanye nokuqinisekiswa kwegumbi; ukuqapha isignali ye-broadband; ukuqapha kanye nokuthola isiqondiso; izinhlelo zokuhlola; kanye namapulatifomu e-RF afakwe emotweni, afakwe phansi, kanye nahlanganisiwe.
Ngenxa yokuthi uchungechunge luhlanganisa inhlanganisela ehlukene ye-gain, i-VSWR, i-polarization, i-RF interface, usayizi, kanye nokucushwa kwemishini, ukukhethwa kwe-antenna kufanele kuqale njalo ngebanga lemvamisa eqondiwe bese kucatshangelwa izidingo zesistimu ephelele ye-RF.
Ukukhetha i-Antenna Ekabili Efanele
Lapho bekhetha imodeli, onjiniyela kufanele baqale banqume ububanzi bemvamisa yokusebenza edingekayo, bese behlola izidingo ze-polarization kanye ne-RF interface.
Amanye amapharamitha afana nalawaI-VSWR, inzuzo, ubukhulu obungokwenyama, isisindo, kanye nokuphathwa kwamandlakufanele futhi kucatshangelwe ngokwesicelo esiqondiwe.
Isibonelo, amamodeli anemvamisa ephansi angaba nobukhulu obukhulu bomshini, kuyilapho amamodeli e-millimeter-wave kanye ne-sub-THz angaba mancane kakhulu. Izidingo zesixhumi nazo ziyashintsha njengoba imvamisa yokusebenza ikhula, kusukela ezixhumini ze-coaxial ezivamile kuya ezixhumini ezikhethekile ze-millimeter-wave.
Usekelo lobuchwepheshe lwe-RF MISO lungasiza amakhasimende ekubukezeni ububanzi bemvamisa, isikhombimsebenzisi se-RF, i-polarization, ukufakwa, kanye nezidingo zokuhlanganiswa kwesistimu lapho ekhetha i-antenna efanelekile ye-biconical.
Iphothifoliyo ye-Broad Biconical Antenna kusuka ku-RF kuya ku-Sub-THz
KusukelaAmamodeli e-broadband angu-0.02–3 GHz to Imiklamo ye-sub-THz engu-297–303 GHz, i-RF MISO Biconical Antenna Series inikeza ukukhetha okuhlukahlukene kwama-antenna obunjiniyela be-RF, ukulinganisa, ukuqapha, kanye nezinhlelo zokusebenza zokuhlanganisa uhlelo.
Njengoba kunezinhlobo eziningi zamaza, ukucushwa kwe-polarization, osayizi bemishini, kanye ne-RF interfaces etholakalayo, lolu chungechunge lunikeza onjiniyela ukuguquguquka kokukhetha i-antenna ngokuya ngezidingo zangempela zendawo yokuhlola noma ipulatifomu ye-RF.
Ukuze uthole ulwazi olwengeziwe mayelana nomodeli noma usizo ngokukhetha i-antenna, xhumana nethimba le-RF MISO ukuze uthole ukwesekwa kobuchwepheshe.
