I-Antenna Yempondo Ejikelezayo Ye-RM-CPHA1840-12, 18–40 GHz

Njengoba izinhlelo zamagagasi e-millimeter ziqhubeka nokukhula kuzo zonke iziteshi zokuxhumana, ukuzwa, ukuhlola, kanye namapulatifomu asemoyeni, onjiniyela badinga ama-antenna angagcina ukusebenza okuthembekile kwe-polarization kanye nemisebe ngaphezu kwefasitela elincane lemvamisa.I-RM-CPHA1840-12I-Antenna Yezimpondo Ezijikelezayo Ezine-Polarizedyenzelwe izinhlelo zokusebenza ze-wideband ezivela ku-18 kuya ku-40 GHz, ehlanganisa ukumbozwa okubanzi kwemvamisa nesakhiwo somshini esincane nesilula.

I-antenna iyatholakala kunoma iyiphikwesokudlaukwahlukana okujikelezayo(I-RHCP) or ukuhlukaniswa kwendilinga kwesandla sobunxele (LHCP). Ukuhlukaniswa kwe-circular kusiza ukunciphisa ukuzwela ekuqondeni okuhlobene phakathi kwama-antenna okudlulisa nokwamukela, okwenza i-RM-CPHA1840-12 ibe usizo kakhulu ezinhlelweni lapho isimo sepulatifomu, isiqondiso sesiginali, noma i-engeli yokufaka ingashintsha khona ngesikhathi sokusebenza noma sokuhlola.

NgeInzuzo ejwayelekile engu-12 dBi, i-antenna inikeza isiqondiso esiwusizo sokulinganisa amagagasi e-millimeter ngenkathi igcina iphrofayili yokuzuza elawulwayo kulo lonke ibhendi yokusebenza. Imiphumela yokulingisa ikhombisa ukwanda kokuzuza engxenyeni ephezulu yebanga lokuphindaphinda, isekela imisebe egxilile kanye nokusebenza okuthuthukisiwe kwezixhumanisi ezindaweni zokuhlola ezivame kakhulu.

Ukufaniswa kwe-impedance okuzinzile kubaluleke ngokulinganayo kuchungechunge lokulinganisa i-broadband. I-RM-CPHA1840-12 inikezai-VSWR ejwayelekile engu-1.5:1, okusiza ukunciphisa amandla abonakalayo nokusekela ukudluliselwa kwamandla okusebenzayo phakathi kwe-antenna kanye nemishini ye-RF exhunyiwe.Isilinganiso se-axial esijwayelekile esingu-2 dBkubonisa ikhwalithi enhle yokwehlukanisa okujikelezayo, okubalulekile lapho onjiniyela bedinga ukugcina ubuqotho be-polarization nokunciphisa ukungalingani kwe-polarization okungafuneki.

I-antenna ihlanganisa i-polarizer eyindilinga, isakhiwo sokuguqulwa kwe-waveguide, kanye nophondo oluyindilinga endaweni ehlelekile. Lo mklamo usekela ukuziphatha kwemisebe okulinganayo ezindaweni eziyinhloko, okwenza i-antenna ifanele ukuhlolwa okuphindaphindwayo kwensimu ekude, ukuhlolwa kwemisebe ye-RF, kanye nokulinganiswa kwe-antenna okuqhathanisayo. Amaphethini emisebe anikezwa kumaza omsindo kusukela ku-18 kuya ku-40 GHz futhi anikeza onjiniyela umbono osebenzayo wokuvela kwemisebe kulo lonke uhla lokusebenza.

Ukuhlanganiswa kwemishini kungenye indlela enamandla omklamo. Ukulinganisa cisheUbude obungu-129.6 mm nobubanzi obungu-28 mm, futhi inesisindo kuphelaamagremu angu-82, i-RM-CPHA1840-12 ingafakwa ezintweni zelebhu ezincane, izinhlelo zokubeka izinto, amapulatifomu ahamba emoyeni, kanye nemishini yamaza e-millimeter eqaphela isikhala. Ukwakhiwa kwayo kwe-aluminium kanye nokuqedwa okupendiwe kunikeza ibhalansi yesisindo esiphansi, ukuqina kwesakhiwo, kanye nokubukeka kobungcweti kwezimboni.

Ukucushwa okujwayelekile kusebenzisa i-Isixhumi esibonakalayo sabesifazane esingu-2.92 mmfuthi isekelaAmandla aphakathi angu-20 WfuthiAmandla aphezulu angu-40 W. Kungaxoxwa ngezilungiselelo ezengeziwe zesixhumi ngokuya ngezidingo zesistimu.

Izinhlelo zokusebenza ezijwayelekile zifaka:

Ukuhlolwa kwe-antenna ekude
Ukulinganiswa kwemisebe ye-RF kanye nokukhishwa komoya
Ukuhlolwa kokuxhumana kwamagagasi e-millimeter
Ukuhlolwa kwe-circular-polarization
Ukuthuthukiswa kwe-radar kanye nohlelo lokuzwa
Amapulatifomu e-Airborne RF
Amaphrojekthi elebhu kanye nokuhlanganiswa kwezinhlelo

NgayoUmkhawulokudonsa we-18–40 GHz, ukusebenza kwe-RHCP noma i-LHCP okukhethekayo, ukufaniswa kwe-impedance okuzinzile, ubukhulu obuncane, kanye nokusebenza okuthembekile kwe-circular-polarization,I-RM-CPHA1840-12inikeza ikhambi eliguquguqukayo lokuhlola okudingakalayo kwamagagasi e-millimeter kanye nezinhlelo zokusebenza zokuthuthukisa uhlelo.
