Ukukhethaumenzi we-antenna yeempondo ezimbiniAyisiyonto yokuthelekisa uluhlu lweefrikhwensi kuphela. Kuvavanyo lwe-broadband RF, i-antenna kufuneka ikwabonelele ngokuthelekiswa kwe-impedance okuzinzileyo, ukuziphatha kwemitha okuqikelelweyo, izihlanganisi ezifanelekileyo, kunye nobukhulu boomatshini obuhambelana nokuseta umlinganiselo. Ezi nkcukacha zichaphazela ngokuthe ngqo ukuphindaphindwa kovavanyo lwe-EMC/EMI, ukulinganiswa kwe-antenna, ukujonga isignali, kunye nokuhlanganiswa kwenkqubo.
I-RF MISO iphuhlisa kwaye ibonelela ngezisombululo ze-antenna ze-broadband horn kwiinjineli ze-RF, abahlanganisi beenkqubo, iilebhu, kunye nabavelisi bezixhobo. Iimodeli ezimeleyo ezingezantsi zizonke zibandakanya0.4 ukuya kwi-40 GHz, okuvumela abasebenzisi ukuba bakhethe i-antenna yebhendi yokusebenza echaziweyo endaweni yokucinga ukuba i-antenna enye igubungela lonke uluhlu.
Kutheni ii-Antennas zeempondo eziphindwe kabini zisetyenziselwa uvavanyo lwe-RF lwe-Broadband
Isakhiwo se-waveguide esinama-ridge amabini sandisa i-bandwidth esebenzisekayo ye-antenna ye-horn ngelixa sigcina i-radiation ebhekisa kwicala kunye ne-linear polarization. Olu dibaniso lwenza i-antenna ibe luncedo xa inkqubo yovavanyo kufuneka isebenze kuluhlu olubanzi lwee-frequency ngaphandle kokutshintsha ii-antenna ngokuphindaphindiweyo.
Ukusetyenziswa okuqhelekileyo kuquka uvavanyo lokukhutshwa kwemitha, uvavanyo lwe-EMC/EMI, ukulinganiswa kokufumana i-antenna kunye nepatheni yemitha, ukuhanjiswa kunye nokwamkelwa kwesignali ye-broadband, ukujongwa, uphononongo, kunye nokufumana indlela. Eyona modeli ilungileyo isaxhomekeke kwibhendi efunekayo, inzuzo oyifunayo, umgama wovavanyo, indawo ekhoyo, ujongano lwesixhumi, kunye nenqanaba lamandla.
Oko Ufanele Ukukuvavanya Xa Ukhetha Umenzi
1. Ukugubungela rhoqo okusekelwe kwibhendi yovavanyo lokwenyani
Qala ngeefrikhwensi zokusebenza eziphantsi neziphezulu ezifunekayo kwinkqubo. Uluhlu olubanzi alungcono ngokuzenzekelayo: i-antenna ekhethiweyo kufuneka ihambelane nebhendi yovavanyo yokwenyani ngelixa ihlangabezana neemeko zokufumana, ububanzi be-beamm, ubungakanani, kunye ne-connector ezifunekayo.

Iinjineli zeRF kufuneka ziqinisekise nokuba amaxabiso achaziweyo aqhelekile okanye aqinisekisiwe kwaye zihlolisise iphepha ledatha langoku ukuze zifumane uqwalaselo oluthengwayo.
3. Ukusebenza kwemisebe kunye nokuqhekeka
Ukugubungela i-broadband kuphela akuchazi ukusebenza kwe-antenna. Iipateni zemitha, ububanzi be-beamm, ukwahlulwa kwe-cross-polarization, kunye nokulungelelaniswa kwe-linear polarization kunokubaluleka ngokulinganayo kwiinkqubo zokulinganisa kunye nokubeka esweni. Ezi mpawu zinceda ekumiseleni i-test geometry, iimfuno zokulungelelanisa, kunye nokungaqiniseki kokulinganisa.
4. Ukudibanisa kunye nokudibanisa oomatshini
Uhlobo lwesixhumi kufuneka luhambelane nesantya sokusebenza, indibano yekhebula, kunye nezixhobo zovavanyo. Ubungakanani obupheleleyo, ubunzima, ulungiselelo lokufakelwa, kunye nokujongwa kwe-antenna nako kuchaphazela ukufakwa kwegumbi, iinkqubo zokubeka, kunye nokuseta uvavanyo oluphathwayo. Umzobo wangoku woomatshini ubalulekile xa i-antenna idityaniswa kwisixhobo okanye iqonga elikhoyo.
5. Amaxwebhu omenzi kunye nonxibelelwano lobugcisa
Umthengisi we-antenna okwaziyo ukusebenzisa i-broadband horn kufuneka anike iinkcukacha ezithile zemodeli kunye nonxibelelwano olucacileyo lobuchwephesha. Ngaphambi kokuba u-odole, yabelana ngoluhlu lweefrikhwensi ezifunekayo, usetyenziso, inzuzo ekujoliswe kuyo, isixhumi, inqanaba lamandla, imida yokufakela, kunye neemeko zokusingqongileyo. Oku kunika umenzi ulwazi olwaneleyo lokuphonononga ukuba imodeli esemgangathweni ifanelekile na.
