Kwiinkqubo zonxibelelwano ze-microwave kunye ne-RF, ukufumana isignali ye-antenna eqinileyo kubalulekile ukuze kusebenze ngokuthembekileyo. Nokuba ungumyili wenkqubo, uMvelisi we-**RF Antenna**, okanye umsebenzisi wokugqibela, ukuqonda izinto eziphucula amandla esignali kunokunceda ukuphucula amakhonkco angenazingcingo. Eli nqaku liphonononga izinto ezibalulekileyo eziphucula amandla esignali ye-antenna, kunye neengcamango ezivela kubavelisi be-**Microwave Antenna** kunye nemizekelo equka **Ii-Antennas zeBiconical** kunye ne **24 GHz Ii-Antennas zeempondo**.
1. Ukuzuza kunye noLawulo lwe-Antena
I-antenna ene-high-gain, efana ne-**24 GHz Horn Antenna**, igxila amandla e-RF kwicala elithile, inyusa kakhulu amandla esignali kuloo msebe. Ii-antenna ezikhokelayo (umz., izitya ze-parabolic, ii-antenna ze-horn) zingcono kuneentlobo ze-omnidirectional (umz., **Biconical Antennas**) kwiikhonkco ze-point-to-point kodwa zifuna ulungelelwaniso oluchanekileyo. **Abavelisi be-Antenna ye-Microwave** yenza ngcono inzuzo ngokuphucula uyilo olufana nohlengahlengiso lwee-engile ze-flare kwii-antenna ze-horn okanye ukubumba i-reflector kwii-antenna ze-dish.
2. Ukunciphisa ilahleko
Ukonakala kwesiginali kwenzeka ngenxa yezi zinto zilandelayo:
- **Ilahleko zeFeedline**: Iintambo ze-coaxial ezikumgangatho ophantsi okanye iiadaptha ze-waveguide zizisa ukuncitshiswa. Iintambo ezilahlekayo kancinci kunye nokuhambelana okufanelekileyo kwe-impedance kubalulekile.
- **Ukulahleka kwezinto**: Ii-antenna conductors (umz., ubhedu, i-aluminium) kunye ne-dielectric substrates kufuneka zinciphise ukulahleka kwe-resistive kunye ne-dielectric.
- **Ukuphazamiseka Kwendalo**: Ukufuma, uthuli, okanye izinto zesinyithi ezikufutshane zinokusasaza imiqondiso. Uyilo oluqinileyo oluvela kubavelisi be-**RF Antenna** lunciphisa ezi ziphumo.
3. Ukwenziwa ngcono kweeFrequency kunye neBandwidth
Iifrikhwensi eziphezulu (umz.,24 GHz) zivumela imisebe emincinci kunye nokwanda okuphezulu kodwa zisengozini yokufunxwa emoyeni. **Ii-Antennas zeBiconical**, kunye ne-bandwidth yazo ebanzi, zitshintshiselana ngokwandisa ukuguquguquka kovavanyo kunye nokusetyenziswa kwamaza amaninzi. Ukukhetha ibhendi yefrikhwensi efanelekileyo kwimeko yokusetyenziswa kubalulekile.

RM-BCA2428-4 （24-28GHz）
Iimveliso ze-antenna ze-RFMiso 24GHz
4. Uvavanyo oluchanekileyo kunye noLungiso
**Uvavanyo lwe-RF Antenna** luqinisekisa ukuba ukusebenza kuyahlangabezana neemfuno. Iindlela ezifana nezi:
- **Imilinganiselo yeChamber ye-Anechoic** ukuqinisekisa iipateni zemitha.
- **I-Network Analyzer ihlola** ilahleko yembuyekezo kunye ne-VSWR.
- **Uvavanyo lwe-Far-Field** ukuqinisekisa i-gain kunye ne-beamwidth.
Abavelisi baxhomekeke kwezi ndlela ukuze balungise ii-antenna ngaphambi kokuba zisetyenziswe.
5. Ukubekwa kwe-Antena kunye noCwangciso lwe-Array
- **Ukuphakama kunye nokuKhanya**: Ukuphakamisa ii-antenna kunciphisa ukukhanya komhlaba kunye nokuthintelwa.
- **Ii-Antenna Arrays**: Ukudibanisa izinto ezininzi (umz., ii-arrays ezicwangcisiweyo) kuphucula amandla esignali ngokuphazamiseka okwakhayo.
Isiphelo
Isignali ye-antenna enamandla iphuma kuyilo olucokisekileyo (ukwanda okuphezulu, izixhobo ezilahlekelwa kancinci), ukukhethwa kwamaza afanelekileyo, uVavanyo lwe-Antenna ye-RF oluqinileyo**, kunye nokusasazwa okufanelekileyo. **Abavelisi be-Antenna ye-Microwave** basebenzisa le migaqo ukubonelela ngezisombululo eziqinileyo ezifana ne-Antennas yeeHorn ze-**24 GHz** kwizicelo ze-millimeter-wave okanye i-**Biconical Antennas** yovavanyo lwe-EMC. Nokuba zeze-radar, i-5G, okanye unxibelelwano lwesathelayithi, ukubeka phambili ezi zinto kuqinisekisa ukusebenza okuphezulu.
