Ukukhethaumenzi we-antenna enophondo oluphindwe kabiliakuyona nje indaba yokuqhathanisa amabanga emvamisa. Ekuhlolweni kwe-broadband RF, i-antenna kumele futhi inikeze ukufaniswa kwe-impedance okuzinzile, ukuziphatha kwemisebe okubikezelwayo, izixhumi ezifanele, kanye nobukhulu bemishini obuhambisana nokusethwa kokulinganisa. Le mininingwane ithinta ngqo ukuphindaphindeka ekuhlolweni kwe-EMC/EMI, ukulinganiswa kwe-antenna, ukuqapha isignali, kanye nokuhlanganiswa kwesistimu.
I-RF MISO ithuthukisa futhi ihlinzeka ngezixazululo ze-antenna ye-broadband horn konjiniyela be-RF, abahlanganisi bezinhlelo, amalebhu, kanye nabakhiqizi bemishini. Amamodeli amele ngezansi ahlanganisa wonke amamodeli.0.4 kuya ku-40 GHz, okuvumela abasebenzisi ukuthi bakhethe i-antenna yebhendi yokusebenza echaziwe kunokucabanga ukuthi i-antenna eyodwa ihlanganisa lonke uhla.
Kungani Ama-Antenna Empondo Ezinezinsika Ezimbili Esetshenziselwa Ukuhlolwa Kwe-RF Ye-Broadband
Isakhiwo se-waveguide esinama-ridge amabili sandisa i-bandwidth esebenzisekayo ye-antenna ye-horn ngenkathi sigcina imisebe eqondisayo kanye ne-linear polarization. Lokhu kuhlanganiswa kwenza i-antenna ibe wusizo lapho uhlelo lokuhlola kumele lusebenze ebangeni elibanzi lemvamisa ngaphandle kokushintsha ama-antenna ngokuphindaphindiwe.
Ukusetshenziswa okuvamile kufaka phakathi ukuhlolwa kokukhishwa kwegesi okubangelwa imisebe, ukuhlolwa kwe-EMC/EMI, ukulinganiswa kokuzuza kwe-antenna kanye nephethini yokukhishwa kwemisebe, ukudluliselwa nokwamukelwa kwesignali ye-broadband, ukubhekwa, ukuhlolwa, kanye nokutholwa kwesiqondiso. Imodeli engcono kakhulu isancike kubhendi edingekayo, inzuzo oyifunayo, ibanga lokuhlola, isikhala esitholakalayo, isixhumi esibonakalayo, kanye nezinga lamandla.
Okufanele Ukuhlole Lapho Ukhetha Umkhiqizi
1. Ukumbozwa kwemvamisa ngokusekelwe kubhendi yokuhlolwa yangempela
Qala ngamaza okusebenza aphansi kakhulu naphezulu adingwa uhlelo. Ububanzi obubanzi abungcono ngokuzenzakalelayo: i-antenna ekhethiwe kufanele ifane nebhendi yokuhlola yangempela ngenkathi ihlangabezana nezimo zokuzuza, ububanzi be-beamm, usayizi, kanye nesixhumi esidingekayo. Uma kuhileleke amabhendi amaningana, qhathanisa ukuhweba phakathi kwemodeli eyodwa ye-broadband nama-antenna amaningi alungiselelwe amabanga amancane.
2. Ukuqhathaniswa kwenzuzo kanye ne-impedance
Amathonya okuzuza axhumanisa isabelomali kanye namandla ensimu, kuyilapho i-VSWR ikhombisa ukuthi amandla adluliselwa kahle kangakanani phakathi komugqa wokuphakelayo kanye ne-antenna. Amanani ashicilelwe kufanele afundwe kanye nezindawo ezincike emvamisa noma nini lapho kungenzeka. Onjiniyela be-RF kufanele futhi baqinisekise ukuthi amanani ashiwo ajwayelekile noma aqinisekisiwe futhi babuyekeze ishidi ledatha lamanje ukuze bathole ukucushwa okuqondile okuthengwayo.
3. Ukusebenza kwemisebe kanye nokwehlukaniswa kwemisebe
Ukumbozwa kwe-broadband kukodwa akuchazi ukusebenza kwe-antenna. Amaphethini okukhanya, ububanzi be-beamm, ukuhlukaniswa kwe-cross-polarization, kanye nokuqondiswa kwe-linear polarization kungabaluleka ngokulinganayo ezinhlelweni zokulinganisa nokuqapha. Lezi zici zisiza ekunqumeni i-test geometry, izidingo zokuqondanisa, kanye nokungaqiniseki kokulinganisa.
4. Ukuhlanganiswa kwesixhumi kanye nomshini
Uhlobo lwesixhumi kumele luhambisane nemvamisa yokusebenza, ukuhlanganiswa kwekhebula, kanye nemishini yokuhlola. Ubukhulu obuphelele, isisindo, ukuhlelwa kokufakwa, kanye nokuqondiswa kwe-antenna nakho kuthinta ukufakwa kwegumbi, izinhlelo zokubeka, kanye nokusethwa kokuhlolwa okuphathekayo. Umdwebo wamanje wemishini ubalulekile lapho i-antenna izohlanganiswa ne-fixture noma ipulatifomu ekhona.
5. Imibhalo yomkhiqizi kanye nokuxhumana kobuchwepheshe
Umhlinzeki we-antenna onekhono lokuxhuma i-broadband kufanele anikeze imininingwane ethile yemodeli kanye nokuxhumana okucacile kobuchwepheshe. Ngaphambi koku-oda, yabelana ngebanga lemvamisa elidingekayo, uhlelo lokusebenza, inzuzo yethagethi, isixhumi, izinga lamandla, imikhawulo yokufaka, kanye nezimo zemvelo. Lokhu kunikeza umenzi ulwazi olwanele lokubuyekeza ukuthi imodeli ejwayelekile iyafaneleka yini.
Ama-antenna e-RF MISO Broadband Horn amele i-RF

RM-BDHA046-10ihloselwe umsebenzi we-broadband osezingeni eliphansi kusukela ku-0.4 kuya ku-6 GHz futhi inomphumela ojwayelekile we-10 dBi. Imininingwane yayo yamanje ibala i-linear polarization, i-30 dB cross-polarization isolation, i-SMA Female connector, kanye nokuphathwa kwamandla okumaphakathi okungaba ngu-500 W.
RM-BDHA118-10ihlanganisa i-1 kuya ku-18 GHz nge-gain ejwayelekile engu-10 dBi. Ubukhulu bayo obuncane buyenza ibe yinto efanelekile yezinhlelo zelebhu ezibanzi lapho kudingeka khona ukumbozwa nge-microwave range.
RM-BDHA440-13Inweba ukumbozwa kusuka ku-4 kuya ku-40 GHz ngenzuzo ejwayelekile engu-13 dBi. Ukucushwa kwamanje kunikeza isixhumi esingu-2.92 mm Female noma esingu-2.4 mm Female futhi sinesisindo esingu-33 g, esisekela imisebenzi yokulinganisa imvamisa ephezulu kanye nokuhlanganisa lapho usayizi omncane ubalulekile khona.
Imininingwane engenhla isekelwe kuma-datasheet emodeli yamanje anikezwe kulokhu kuqhathanisa. Qinisekisa i-datasheet yakamuva kanye nokucushwa okudingekayo nge-RF MISO ngaphambi koku-oda.
Ukusebenza ne-RF MISO njengomkhiqizi we-Antenna
I-RF MISO ihlanganisa ucwaningo nentuthuko ye-antenna, ubunjiniyela, ukukhiqizwa, kanye nokuthengisa ngaphakathi kwenhlangano eyodwa. Kubathengi bobunjiniyela, ukuxhumana okuqondile kobuchwepheshe kusiza ukuxhumanisa izidingo zohlelo lokusebenza nemodeli ethile kanye nemibhalo yamanje. I-RF MISO inikeza ama-antenna ezinhlelo zokusebenza ze-RF kanye ne-microwave, kufaka phakathi ama-antenna e-broadband horn, ama-antenna e-gain horn ajwayelekile, ama-antenna e-corrugated horn, ama-antenna e-waveguide, kanye nezinye izixazululo ze-antenna.
Uma uxhumana ne-RF MISO, nikeza ububanzi bemvamisa yokusebenza, uhlelo lokusebenza lokuhlola noma uhlelo oluhlosiwe, isixhumi esithandwayo, ithagethi yokuzuza, isidingo samandla, imikhawulo yokufaka, kanye nanoma iyiphi idatha yokulinganisa edingekayo. Ithimba lobuchwepheshe lingabuyekeza amamodeli atholakalayo futhi lisize ekutholeni indawo efanele yokuqala.
imibuzo ejwayelekile ukubuzwa
Uyini umehluko phakathi kophondo olunezinhlangothi ezimbili kanye nophondo olujwayelekile lokuzuza?
Uphondo olunemigqa emibili luvame ukukhethwa ukuze lumbozwe imvamisa ebanzi. Uphondo olujwayelekile lokuzuza luvame ukusetshenziswa phezu kwebhendi yokuqondisa amagagasi encane lapho kudingeka ireferensi yokuzuza echazwe kahle. Ukukhetha okulungile kuncike ku-bandwidth, inzuzo, iphethini, indlela yokuhlola, kanye nezidingo zokulinganisa.
Ingabe i-antenna eyodwa ye-RF MISO ingamboza i-0.4 kuya ku-40 GHz?
Cha. Isibalo esingu-0.4–40 GHz sichaza ukumbozwa okuhlangene kwamamodeli amele kulesi sihloko. I-antenna ngayinye inebhendi yayo yokusebenza ecacisiwe, ngakho abasebenzisi kufanele bakhethe imodeli ngokusekelwe ebangeni labo langempela lemvamisa.
Yiluphi ulwazi okufanele ngiluthumele kumkhiqizi we-antenna ye-horn?
Nikeza imvamisa encane nephezulu, uhlelo lokusebenza, isidingo sokuthola, i-polarization, isixhumi, izinga lamandla, isikhala sokufaka, indlela yokufaka, kanye nanoma iyiphi idatha yokuhlola edingekayo. Izidingo eziphelele zinciphisa amaphutha okukhetha futhi zisheshise ukubuyekezwa kobuchwepheshe.
Yimuphi imodeli okufanele ngiyikhethele ukuhlolwa kwe-wideband?
Impendulo incike kubhendi kanye nokusethwa kwayo. I-RM-BDHA046-10 ikhuluma ngo-0.4–6 GHz, i-RM-BDHA118-10 ihlanganisa i-1–18 GHz, kanti i-RM-BDHA440-13 ihlanganisa i-4–40 GHz. I-Gain, i-connector, ubukhulu, amandla, kanye nokusebenza kwemisebe kufanele kubuyekezwe ngaphambi kokukhetha.
Hlola ama-antenna e-RF MISO Broadband Horn
Qhathanisa amamodeli engeziwe noma uxhumane ne-RF MISO ngebanga lakho lokuvama nezidingo zokuhlanganiswa.
