I-Antenna Yempondo Eyindilinga Ephindwe Kabili Ye-RM-DCPHA12-10 Yezinhlelo Zokusebenza Ze-RF Ezingu-1–2 GHz

Ezinhlelweni ze-RF ezithuthukisiwe, ukusebenza kwe-antenna akunqunywa yinzuzo kuphela. Ukuguquguquka kwe-polarization, ukufaniswa kwe-impedance, ubumsulwa bemisebe, ukuhlukaniswa kwangaphambili kuya emuva, kanye nekhono lokuphatha amandla konke kuthinta ukuthembeka kwesixhumanisi sokulinganisa noma sokuxhumana. Ama-RF MISO'sI-RM-DCPHA12-10I-Antenna Yophondo Oluphindwe Kabili Oluyindilingaihlanganisa lezi zidingo ndawonye kwisisombululo sobungcweti se-antenna esimbozaIbanga lemvamisa engu-1–2 GHz.

Yakhelwe ukusebenza kwe-polarization eyindilinga emibili,I-RM-DCPHA12-10ifaneleka kahle ezinhlelweni lapho ukulawulwa kwe-polarization kubalulekile noma lapho ukuqondiswa okuhlobene phakathi kwama-antenna okudlulisa nokwamukela kungashintsha khona. I-polarization eyindilinga ingasiza ekunciphiseni ukuzwela ekulinganisweni kwe-antenna futhi isekele ukwamukelwa kwesignali okuzinzile ezindaweni eziyinkimbinkimbi zokusabalala. Amandla e-polarization eyindilinga ephindwe kabili anikeza onjiniyela ukuguquguquka okukhulu lapho behlola ukusebenza kwesistimu okuncike ku-polarization.

I-antenna iyalethaInzuzo ejwayelekile engu-10 dBi, enikeza isiqondiso esiwusizo sokuhlola i-RF, ukuqapha isignali, ukulinganisa i-antenna, ukuthola isiqondiso, kanye nokuhlanganiswa kwesistimu. Imiphumela yokulingisa ikhombisa impendulo ebushelelezi yokuzuza kulo lonke ibhendi yokusebenza, kanye nomsebe wemisebe uba mncane kancane kancane njengoba imvamisa ikhula. Lokhu kuziphatha okubikezelwayo kubalulekile ekuhlolweni kwelabhorethri, ukulinganisa okuqhathanisayo, kanye nokusetshenziswa kwe-RF okuqondisiwe lapho kudingeka khona ukulawulwa komsebe okuqhubekayo.

Ukudluliselwa kwesignali okusebenzayo kusekelwa yi-i-VSWR ejwayelekile engu-1.3:1Amajika e-VSWR alingisiwe ezimo ezimbili ze-polarization ahlala ehambisana kakhulu nebhendi engu-1-2 GHz, esiza ekunciphiseni amandla abonakalayo nokugcina ukusebenza okuzinzile. I-antenna iphinde inikezeUkusebenza okujwayelekile kwe-cross-polarization okungu-40 dB, esekela ubumsulwa obuqinile be-polarization kanye nokuhlukaniswa okuthuthukisiwe phakathi kwezingxenye ze-polarization ezifiselekayo nezingafuneki.

A Isilinganiso esijwayelekile sangaphambili kuya emuva esingu-50 dBkuqinisa ukusebenza kokuqondisa ngokunciphisa imisebe ebheke ngemuva kwe-antenna. Lesi sici siwusizo ikakhulukazi ezinhlwini zokuhlola i-antenna, ukutholwa kwe-EMI, ukuhlola, izinhlelo zokuthola isiqondiso, kanye nezinhlelo zokusebenza zokuqapha lapho amasignali afika evela eziqondisweni ezingafuneki angathinta ukunemba kokulinganisa.

Ukuze kuhlangatshezwane nezidingo ezahlukene zamandla kanye ne-system-interface, i-RM-DCPHA12-10 itholakala ngezinguqulo ezimbili.I-RM-DCPHA12-10Sisebenzisa isikhombikubona se-SMA-Female futhi iyasekelaAmandla wegagasi eliqhubekayo angu-50 W, okwenza ifanelekele izinhlelo zelebhu ezivamile kanye nezinhlelo zokulinganisa. Amandla aphezuluRM-DCPHA12-10Nifakwe isikhombikubona se-N-Female futhi isekela kufika ku-Amandla wegagasi eliqhubekayo angu-500 Wukuze uthole izindawo zokudlulisa ezidinga kakhulu kanye nezivivinyo.

Yakhiwe nge-aluminium enesiphetho esimnyama esipendwe ngopende, i-antenna ihlanganisa amandla omshini nokubukeka kobungcweti kwezimboni. Ubukhulu bayo buphelele bucishe bube334.0 × 214.1 × 224.4 mm, enesisindo3.163 kg, okuvumela ukuhlanganiswa okuqondile kumapulatifomu okuhlola angaguquki, izinhlelo zokubeka, ububanzi be-antenna, kanye nemishini ekhethekile ye-RF.

Izinhlelo zokusebenza ezijwayelekile zifaka:

• Ukutholwa kwe-EMI nokuhlolwa kwe-electromagnetic
• Ukuthola isiqondiso kanye nokuqondiswa kwesignali
• Ukuqapha kokuhlola kanye nokuqapha i-RF
• Ukuqhathaniswa kokuzuza kwe-antenna
• Ukulinganiswa kwephethini yemisebe
• Ukuhlolwa kokuxhumana kanye nohlelo lwe-radar
• Ukuhlolwa kwe-RF enamandla aphezulu kanye nokuhlanganiswa kwesistimu

Ngobubanzi bayo obungu-1-2 GHz, ukuhlukaniswa okubili okuyindilinga, inzuzo eqinile, i-VSWR ephansi, ubumsulwa obuphezulu bokuhlukaniswa, ukusebenza okuhle kakhulu ukusuka phambili kuya emuva, kanye ne-interface yamandla aphezulu ongayikhetha,I-Antenna Yempondo Ephindwe Kabili Ye-RM-DCPHA12-10inikeza ikhambi eliguquguqukayo nelithembekile lokulinganisa i-RF kanye nezinhlelo zokuxhumana zobungcweti.
