I-RF MISO | Umhlahlandlela wokukhetha i-Antenna
A i-antenna yelensiisebenzisa ilensi ukulawula ukusatshalaliswa kwesigaba segagasi likagesi kagesi. Ku-antenna yelensi yophondo, uphondo lukhanyisa ilensi ye-dielectric ebumba umsebe ophumayo. Inzuzo engokoqobo akuyona nje inzuzo ephezulu: ilensi ingasiza ekwakheni umsebe oqondisayo noma amandla agxilile ebangeni elithile lokusebenza.
Kunjiniyela be-RF kanye namaqembu okuthenga, umbuzo wokuqala uthi:Ingabe uhlelo lokusebenza ludinga ugongolo olukude noma indawo eqondile?Lo mhlahlandlela uchaza umehluko, imininingwane ebalulekile, kanye nemikhiqizo emibili ye-RF MISO ekhombisa izidingo ezahlukene zokukhetha.

Isebenza Kanjani I-Antena Yelensi?
Uphondo lokuphakelayo lukhiqiza i-wavefront enesigaba esihlukahluka kuyo yonke indawo ekhanyisiwe. Ilensi ye-dielectric yethula ukubambezeleka kwesigaba okuhlukahluka ngokwendawo ngesimo sayo, izakhiwo zezinto ezibonakalayo, noma kokubili. Ukuze kube nokuhlelwa kwe-collimating, ilensi ivala umehluko wobude bendlela ngakho i-wavefront evelayo icishe ibe yi-planar. I-aperture yangempela, elinganiselwe isakhiqiza i-diffraction kanye ne-beam enobubanzi be-angular obungeyona i-zero.
Indawo yokuphakela ibalulekile. Isikhungo sayo sesigaba esisebenzayo kufanele sihambisane nomklamo welensi; isikhungo sesigaba asiyona ngempela indawo evulekayo yempondo. Ukukhanya kokuphakelayo, ukuhambisana kanye nesikhala kuthinta iphethini ephumayo. Ucwaningo lwaseyunivesithi mayelana nezinhlelo ze-horn-lens luchaza lobu budlelwano kanye nendima yalo ekufezeni isigaba esiphumayo esifanayo.[1]
Amalensi e-RF awagcini nje ngengilazi yokukhanya. Imiklamo ye-microwave ingasebenzisa izinto ze-dielectric ezilahlekelwa kancane njenge-PTFE noma i-polyethylene; izinto ezifanele zincike ekuvameni, ekulahlekelweni kanye nezidingo zemishini. Ilensi engasebenzi ayikhulisi amandla e-RF. Noma yikuphi ukuthuthuka kokuzuza kuvela ekusabalaleni kwemisebe kanye nokusebenza kahle, lapho ukulahleka kwezinto kanye nokukhanya kusekhona.
Ukugxila kwe-Collimation vs. Spot
I-antenna yophondo yelensi yokugxila endaweni ye-RF MISO RM-SFLHA90-25. Izindawo zokugxila zangempela zinobukhulu obulinganiselwe; ireferensi yebanga lokusebenza kumele ichazwe kwi-antenna ekhethiwe.
Umsebe oqondisa indlela
Uma isidingo siwukudluliswa okuqondiswayo noma ukulinganiswa kwe-antenna, hlola i-gain vs frequency, ububanzi be-beamwidths ye-E- kanye ne-H-plane, ama-sidelobes kanye ne-cross-polarization. Ugongolo oluncane lwenza futhi ukukhomba kanye nokuqondanisa kwe-fixture kubaluleke kakhulu. Ungacabangi ukuthi uphondo lwelensi olune-gain ephezulu lunikeza ibanga eliqondile eliseduze nensimu.
Isifunda sokulinganisa sendawo
Uphondo lwelensi olugxile endaweni ethile lugxila ekukhanyeni okuzungeze indiza eqondiwe ebangeni elilinganiselwe. Lokhu kuyasiza ekuhleleni okufanelekile kokuchaza izinto ezikhululekile, lapho usayizi wesampula kanye nejiyometri yokukhanyisa kuthinta khona ukulinganiswa. Ucwaningo mayelana nokulinganiswa kwezinto ezigxile kuma-microwave lubonisa ukuthi kungani izici zensimu yendiza egxile endaweni ethile zibalulekile kanye nosayizi wezindawo.[2]
Cacisa ibanga elidingekayo nokuthi lilinganiswa kanjani, imvamisa yokusebenza, ubukhulu besampula kanye nendawo ekhanyisiwe eyamukelekayo. Buza ukuthi ububanzi bendawo buchazwe ezingeni lika-3 dB, izinga lika-10 dB, i-null yokuqala, noma enye indlela. Izinombolo ezisebenzisa izincazelo ezahlukene azifani ngqo.
Izibonelo ezimbili ze-RF MISO Lens Horn Antenna
Lezi zincazelo ezilandelayo zivela kuma-datasheet e-RF MISO ahlobene nemodeli ethile. Lawa yi-amabhendi okusebenza ahlukene kanye nokucushwa, hhayi ama-antenna angashintshaniswayo.

*Ubude be-focal kanye nosayizi we-spot kubhalwe kukholomu ejwayelekile ye-datasheet. Ithebula layo alibonisi umkhawulo wosayizi we-spot noma imvamisa yokubhekisela. Qinisekisa lezi zimo kanye nereferensi yebanga nge-RF MISO ngaphambi kokuchaza i-fixture yesampula. Akukho nzuzo etholakala kusukela kusijobelelo semodeli ye-RM-SFLHA90-25.
Okufanele Uhlole Ngaphambi Kokukhetha Umkhiqizi
- Ibhendi yokusetshenziswa kanye nokusebenza.Sho ukuthi udinga isixhumanisi esiqondisayo, ukulinganiswa kwe-antenna noma ukukhanya kwesampula okusendaweni. Sebenzisa ibhendi yomkhiqizo eqondile, hhayi ububanzi obuphelele obuhambisana nokuqokwa kwe-waveguide.
- Izincazelo zokusebenza.Hlukanisa amanani ajwayelekile emikhawulweni eqinisekisiwe. I-VSWR ephansi iyodwa ayimiseli ukukhuphuka, ikhwalithi yokukhanya noma ukunemba kokulinganisa.
- Ubufakazi obungemuva kwalezi zindaba.Buza ukuthi yimiphi idatha elingisiwe nokuthi yimiphi elinganiswayo. Ama-datasheet e-RF MISO axhunyiwe abeka izigaba zesakhiwo sawo njengedatha yokulingisa; lokhu akufanele kwethulwe njengemibiko yokuhlola yamayunithi ngamanye.
- Ukuhlanganiswa kwemishini kanye ne-RF.Hlola isixhumi sangaphandle noma i-flange, umdwebo wokufaka, ukubekezelela ukuhamba nokuqondanisa okutholakalayo. Faka ukulahlekelwa yi-adaptha nekhebula kusabelomali sesistimu.
- Izimo zephrojekthi.Cacisa amandla, indawo kanye nobuningi. Ubuso belensi abubona, ngokwalo, ubufakazi bokumbozwa okungenawo umoya noma isilinganiso esithile sendawo.
Ukuhlanganiswa kwelensi kuhilela ukuhweba: ukulungiswa kwesigaba kanye nokuma kwe-beam kungaba usizo, kodwa ukulahlekelwa kwelensi, usayizi wokuvula, isisindo, ukuhambisana kanye nezindleko kusadinga ukubuyekezwa. Uphondo lwelensi noma isibonisi akusona isinqumo esingcono kakhulu emhlabeni wonke; isinqumo kufanele silandele ukusatshalaliswa kwensimu kanye nemvilophu yemishini edingwa yisicelo sakho.
Sebenza ne-RF MISO ekukhetheni amamodeli
I-RF MISO ingumkhiqizi we-antenna kanye nomhlinzeki oseChengdu, eShayina.I-R&Dfuthiukuhlolwa kwe-antennaAmakhasi ethula imisebenzi yobunjiniyela yenkampani. Ukuze uthole umbuzo we-antenna yelensi, thumela ibhendi yakho yemvamisa, i-polarization, i-gain noma i-focusing objective, i-interface kanye nemikhawulo yokufaka ukuze ithimba likwazi ukubuyekeza imodeli kanye nemibhalo efanele.
Thola i-antenna yophondo lwelensi yephrojekthi yakho ye-RF.

imibuzo ejwayelekile ukubuzwa
Ingabe i-antenna yelensi ihlala ikhiqiza umsebe omncane?
Cha. Ububanzi bomsebe buxhomeke ekuvulekeni, imvamisa, ukukhanya kwe-feed kanye nomklamo welensi. Imodeli ye-broadband kufanele ihlolwe kulo lonke ibhendi elidingekayo, hhayi ngesibalo esisodwa sokuzuza kwesihloko.
Ingabe uphondo lwelensi olujwayelekile lungathatha indawo ye-antenna egxile endaweni ethile?
Hhayi ngaphandle kokuqinisekiswa. Ukwanda okucacisiwe akuqinisekisi ibanga elidingekayo lokugxila, ububanzi bebala noma ukusatshalaliswa kwensimu endizeni yesampula eseduze.
Yini okufanele ihlanganiswe yi-RFQ?
Faka ibhendi yokusebenza, uhlelo lokusebenza, i-polarization, isidingo sokuthola noma sosayizi webala, ibanga lokusebenza, isikhombimsebenzisi se-RF, imikhawulo yokufaka kanye nobuningi. Khomba ukuthi yimaphi amanani okusebenza okumele aqinisekiswe.
