I-RM-CPHA1840-12 I-Antenna yePolarized Horn ejikelezayo yoVavanyo lwe-18–40 GHz Millimeter-Wave

Njengoko iinkqubo ze-millimeter-wave ziqhubeka nokukhula kuzo zonke iindlela zonxibelelwano, ukuva, ukuvavanya, kunye namaqonga omoya, iinjineli zifuna ii-antenna ezinokugcina i-polarization ethembekileyo kunye nokusebenza kwemitha ngaphezulu kwefestile encinci ye-frequency.RM-CPHA1840-12I-Antenna yeempondo ezijikelezileyo ezijikelezayoyenzelwe usetyenziso lwe-wideband oluvela kwi18 ukuya kwi-40 GHz, edibanisa ukugubungela okubanzi kwefrikhwensi kunye nesakhiwo soomatshini esincinci nesikhaphukhaphu.

I-antenna ifumaneka nokuba kukuphi naisandla sasekhohloi-polarization ejikelezayo(i-RHCP) or i-polarization yesangqa esisekhohlo (LHCP). I-circular polarization inceda ekunciphiseni uvakalelo kwi-relative orientation phakathi kwee-antenna zokudlulisa nezokwamkela, okwenza i-RM-CPHA1840-12 ibe luncedo ngakumbi kwiinkqubo apho isimo sengqondo seqonga, isikhokelo sesignali, okanye i-engile yokufakela inokutshintsha ngexesha lokusebenza okanye uvavanyo.

NgeInzuzo eqhelekileyo ye-12 dBi, i-antenna inika isikhokelo esiluncedo sokulinganisa amaza e-millimeter ngelixa igcina iprofayili yokuzuza elawulwayo kuyo yonke ibhendi yokusebenza. Iziphumo zokulinganisa zibonisa ukwanda kokuzuza ukuya kwinxalenye ephezulu yoluhlu lwamaza, ixhasa imitha egxile kuyo kunye nokusebenza okuphuculweyo kwekhonkco kwiindawo zovavanyo oluphezulu.

Ukuhambelana kwe-impedance ezinzileyo kubaluleke ngokulinganayo kwikhonkco lokulinganisa i-broadband. I-RM-CPHA1840-12 inikezela ngei-VSWR eqhelekileyo ye-1.5:1, inceda ekunciphiseni amandla abonakalayo kwaye ixhase ukudluliselwa kwamandla okusebenzayo phakathi kwe-antenna kunye nezixhobo ze-RF ezixhunyiweyo.2 dB umlinganiselo oqhelekileyo we-axialibonisa umgangatho olungileyo we-circular-polarization, nto leyo ebalulekileyo xa iinjineli zifuna ukugcina ukuthembeka kwe-polarization kunye nokunciphisa ukungalingani kwe-polarization okungafunekiyo.

I-antenna idibanisa i-polarizer ejikelezayo, isakhiwo sotshintsho lwe-waveguide, kunye ne-conical horn kwindibano elungelelanisiweyo. Olu lwakhiwo luxhasa ukuziphatha kwe-beam ngokulinganayo kwiiplani eziphambili, okwenza i-antenna ifaneleke kuvavanyo oluphindaphindwayo lwe-far-field, uvavanyo lwe-RF radiation, kunye nokulinganiswa kwe-antenna ethelekiswayo. Iipateni ze-radiation ezibonelelwa kwiifrequencies ukusuka kwi-18 ukuya kwi-40 GHz zikwanika iinjineli umbono osebenzayo wokuguquka kwe-beam kulo lonke uluhlu lokusebenza.

Ukuhlanganiswa koomatshini yenye indlela enamandla ngayo uyilo. Ukulinganisa malungaUbude obuyi-129.6 mm kunye nobubanzi obuyi-28 mm, kwaye inobunzima kuphelaIigram ezingama-82, i-RM-CPHA1840-12 ingafakelwa kwiindawo ezincinci zelebhu, iinkqubo zokubeka izinto, amaqonga omoya, kunye nezixhobo ze-millimeter-wave eziqonda isithuba. Ulwakhiwo lwayo lwe-aluminium kunye nokugqitywa kwayo okupeyintiweyo kubonelela ngokulinganisela kobunzima obuphantsi, ukuqina kwesakhiwo, kunye nenkangeleko yobungcali kwimizi-mveliso.

Uqwalaselo oluqhelekileyo lusebenzisa2.92 mm Ujongano lwabasetyhinikunye neenkxasoAmandla aphakathi angama-20 WkwayeAmandla aphezulu angama-40 W. Kunokuxoxwa ngezinye iindlela zokumisela isixhumi ngokweemfuno zenkqubo.

Izicelo eziqhelekileyo ziquka:

• Uvavanyo lwe-antenna olukude
• Umlinganiselo wemitha ye-RF kunye nokukhutshwa komoya
• Uvavanyo lonxibelelwano lwamaza e-millimeter
• Uvavanyo lwe-circular-polarization
• Uphuhliso lweradar kunye nenkqubo yokuva
• Iiplatifomu zeRF eziqhutywa ngomoya
• Iiprojekthi zelebhu kunye nokudibanisa iinkqubo

Ngenxa yayoI-bandwidth ye-18–40 GHz, ukusebenza kwe-RHCP okanye i-LHCP ekhethiweyo, ukuhambelana kwe-impedance okuzinzileyo, ubungakanani obuncinci, kunye nokusebenza okuthembekileyo kwe-circular-polarization,RM-CPHA1840-12ibonelela ngesisombululo esiguquguqukayo sovavanyo olufuna amandla e-millimeter-wave kunye nezicelo zophuhliso lwenkqubo.
