Ii-Antennas zeLens: Imigaqo yokusebenza kunye neSikhokelo soKhetho lwe-RF MISO

I-RF MISO | Isikhokelo sokukhetha ii-antenna

A i-eriyali yelensiisebenzisa ilensi ukulawula ukusasazwa kwesigaba se-electromagnetic wave. Kwi-antenna yelensi yophondo, uphondo lukhanyisa ilensi ye-dielectric ebumba umqadi ophumayo. Inzuzo esebenzayo ayikokufumana nje okuphezulu: ilensi inokunceda ekwakheni umqadi obhekisa kwicala okanye amandla agxile kumgama othile wokusebenza.

Kwiinjineli zeRF kunye namaqela okuthenga, umbuzo wokuqala ngulo:Ingaba isicelo sifuna umqadi okude okanye indawo eqingqiweyo?Esi sikhokelo sichaza umahluko, iinkcukacha ezibalulekileyo, kunye neemveliso ezimbini ze-RF MISO ezibonisa iimfuno ezahlukeneyo zokukhetha.

Isebenza njani i-Antena yeLensi?

I-feed horn ivelisa i-wavefront ene-phase yayo eyahluka kulo lonke ummandla okhanyayo. Ilensi ye-dielectric ingenisa ukulibaziseka kwe-phase ngokwendawo ngokuma kwayo, iimpawu zezinto, okanye zombini. Kwilungiselelo le-collimating, ilensi ihlawula umahluko phakathi kobude bendlela ukuze i-wavefront evelayo ibe malunga ne-planar. I-aperture yokwenyani, enomda isavelisa i-diffraction kunye nomqadi onobubanzi obungengo-zero.

Indawo yokutyela ibalulekile. Iziko layo elisebenzayo lesigaba kufuneka lihambelane noyilo lwelensi; iziko lesigaba alikho kwisithuba sempondo. Ukukhanya kwesondlo, ukulungelelaniswa kunye nesithuba sesithuba kuphembelela ipateni ephumayo. Uphando lweyunivesithi kwiinkqubo zeelensi zephondo luchaza olu lwalamano kunye nendima yalo ekufezekiseni inqanaba elifanayo lokuphuma.[1]

Iilensi zeRF azipheleli kwiglasi yokukhanya kuphela. Uyilo lwe-microwave lungasebenzisa izinto ze-dielectric ezilahleka kancinci ezifana ne-PTFE okanye i-polyethylene; izinto ezifanelekileyo zixhomekeke kwimvamisa, ilahleko kunye neemfuno zoomatshini. Ilensi engasebenziyo ayiwandisi amandla e-RF. Naluphi na uphuculo lwenzuzo luvela ekusasazweni kwemitha kunye nokusebenza kakuhle, kunye nokulahleka kwezinto kunye nokukhanya okusekho.

Ukugxila kwiCollimation vs. Spot Focus

I-antenna yelensi egxile kwindawo ye-RF MISO RM-SFLHA90-25. Iindawo ezijolise kwindawo yokwenyani zinobukhulu obulinganiselweyo; isalathiso somgama wokusebenza kufuneka sichazwe kwi-antenna ekhethiweyo.

Umqadi obhekisa kwicala

Xa imfuneko ikukulinganisa uthumelo oluya kwicala elithile okanye umlinganiselo we-antenna, vavanya i-gain vs frequency, ububanzi be-E- kunye ne-H-plane beamwidths, i-sidelobes kunye ne-cross-polarization. I-beam emxinwa ikwabangela ukuba ulungelelwaniso lwe-pointing kunye ne-fixture lube lubaluleke ngakumbi. Musa ukucinga ukuba uphondo lwelensi olufumana i-high-gain lubonelela ngomgama othile ongqameneyo okufutshane nentsimi.

Indawo yokulinganisa yendawo

Uphondo lwelensi olugxile kwindawo ethile lugxila ekukhanyeni okujikeleze indiza ekujoliswe kuyo kumgama oqingqiweyo. Oku kuluncedo kumalungiselelo afanelekileyo okuchonga izinto ezikwindawo ekhululekileyo, apho ubungakanani besampulu kunye nejometri yokukhanyisa kuchaphazela umlinganiselo. Uphando malunga nokulinganiswa kwezinto ze-microwave ezigxile kwindawo ethile lubonisa ukuba kutheni iimpawu zentsimi ye-focal-plane zibalulekile kunye nobukhulu beendawo.[2]

Cacisa umgama ofunekayo kunye nendlela olinganiswa ngayo, imvamisa yokusebenza, ubungakanani besampuli kunye nendawo ekhanyisiweyo eyamkelekileyo. Buza ukuba ingaba ububanzi bendawo buchazwe kwinqanaba le-3 dB, inqanaba le-10 dB, i-null yokuqala, okanye enye ikhrayitheriya. Amanani asebenzisa iinkcazo ezahlukeneyo awafani ngokuthe ngqo.

Imizekelo emibini ye-RF MISO Lens Horn Antenna

Ezi nkcukacha zilandelayo zivela kwiinkcukacha zedatha ze-RF MISO ezidityanisiweyo zemodeli ethile. Ezi zeziiibhendi ezahlukeneyo zokusebenza kunye noqwalaselo, hayi ii-antenna ezitshintshanayo.

*Ubude befocal kunye nobukhulu bebala zidweliswe kwikholamu eqhelekileyo yedatha. Itheyibhile yayo ayibonisi umda wobungakanani bebala okanye ireferensi. Qinisekisa ezi meko kunye nereferensi yomgama ngeRF MISO ngaphambi kokuba uchaze isampuli. Akukho xabiso lenzuzo eliqikelelwayo kwi-RM-SFLHA90-25 model suffix.

Oko Ufanele Ukujonga Ngaphambi Kokukhetha Umenzi

• Ibhendi yokusetyenziswa kunye nokusebenza.Xela ukuba ufuna ikhonkco elibhekisa kwicala elithile, umlinganiselo we-antenna okanye ukukhanya kwesampuli okukufutshane. Sebenzisa ibhendi yemveliso echanekileyo, hayi uluhlu olupheleleyo oluhambelana nophawu lwe-waveguide.
• Iinkcazo zokusebenza.Yahlula amaxabiso aqhelekileyo kwimida eqinisekisiweyo. I-VSWR ephantsi yodwa ayimiseli ukuchaneka kwe-gain, beam okanye umlinganiselo.
• Ubungqina obungasemva kwebali.Buza ukuba zeziphi idatha ezilinganiswayo nezilinganiswayo. Amaphepha edatha eRF MISO adityanisiweyo abhala amacandelo awo eploti njengedatha yokulinganisa; ezi akufuneki ziboniswe njengeengxelo zovavanyo lweyunithi nganye.
• Ukuhlanganiswa koomatshini kunye ne-RF.Jonga isixhumi sangaphandle okanye iflange, umzobo wokufakelwa, ukunyamezela ukuhamba kunye nokulungelelaniswa okufumanekayo. Faka ukulahleka kweadaptha kunye nekhebula kuhlahlo lwabiwo-mali lwenkqubo.
• Iimeko zeprojekthi.Cacisa amandla, indawo engqongileyo kunye nobungakanani. Ubuso belensi abubodwa ubungqina bokuba igqunyiwe okanye ukuba ikwimeko ethile.

Ukuhlanganiswa kweelensi kubandakanya utshintshiselwano: ukulungiswa kwesigaba kunye nokumila kwemitha kunokuba luncedo, kodwa ukulahleka kweelensi, ubungakanani bomngxuma, ubunzima, ukulungelelaniswa kunye neendleko kusafuneka kuphononongwe. Akukho phondo lelensi okanye isibonisi esingcono kwihlabathi liphela; isigqibo kufuneka silandele ukusasazwa kwentsimi kunye nemvulophu yoomatshini efunekayo kwisicelo sakho.

Sebenza ne-RF MISO ekuKhethweni kweeModeli

I-RF MISO ngumvelisi kunye nomthengisi wee-antenna oseChengdu, eTshayina.Uphando noPhuhlisokwayeuvavanyo lwe-antennaAmaphepha azisa imisebenzi yobunjineli yenkampani. Ukuze ufumane umbuzo nge-antenna yelensi, thumela ibhendi yakho yefrikhwensi, i-polarization, i-gain okanye i-focusative objective, i-interface kunye nemida yokufakela ukuze iqela likwazi ukujonga imodeli kunye namaxwebhu afanelekileyo.

Imibuzo ebuzwa qho

Ngaba i-antenna yelensi isoloko ivelisa umqadi omxinwa?

Hayi. Ububanzi be-beamwidth buxhomekeke kwi-aperture, i-frequency, ukukhanya kwe-feed kunye noyilo lwelensi. Imodeli ye-broadband kufuneka ihlolwe kuyo yonke ibhendi efunekayo, kungekhona ngomfanekiso omnye we-headline gain.

Ngaba uphondo lwelensi oluqhelekileyo lunokuthatha indawo ye-antenna egxile kwindawo ethile?

Akunakuqinisekiswa. Ukunyuka okuchaziweyo akuqinisekisi umgama ofunekayo wokugxila, ububanzi bebala okanye ukusasazwa kwentsimi kwiplane yesampulu ekufutshane.

Yintoni ekufuneka iqukwe yi-RFQ?

Faka ibhendi yokusebenza, usetyenziso, i-polarization, imfuneko yobukhulu be-gain okanye i-spot, umgama wokusebenza, i-RF interface, imida yokufakela kunye nobungakanani. Chonga ukuba zeziphi ixabiso lokusebenza ekufuneka liqinisekiswe.
