Ii-antenna ze-microwave, kuquka ii-antenna ze-X-band horn kunye nee-antenna ze-high-gain waveguide probe, zikhuselekile ngokwemvelo xa ziyilwe kwaye zisebenza ngokuchanekileyo. Ukhuseleko lwazo luxhomekeke kwizinto ezintathu ezibalulekileyo: ubuninzi bamandla, uluhlu lwamaza, kunye nobude bexesha lokuvezwa.
1. Imigangatho yoKhuseleko lweMisebe
Imida yoLawulo:
Ii-antenna ze-microwave ziyahambelana nemida yokuvezwa yi-FCC/ICNIRP (umz., ≤10 W/m² kwiindawo zikawonke-wonke ze-X-band). Iinkqubo zeradar ze-PESA zifaka ukucima kwamandla ngokuzenzekelayo xa abantu besondela.
Impembelelo yeFrequency:
Iifrikhwensi eziphezulu (umz., i-X-band 8–12 GHz) zinobunzulu obungena kancinci (<1mm eluswini), nto leyo enciphisa umngcipheko wokonakala kwezicubu xa kuthelekiswa ne-RF engaphantsi.
2. Iimpawu zoKhuseleko loYilo
Ukuphucula ukusebenza kakuhle kwe-antenna:
Uyilo olusebenza kakuhle kakhulu (>90%) lunciphisa imitha elahlekileyo. Umzekelo, ii-antenna ze-waveguide probe zinciphisa ii-sidelobes ukuya kwi-<–20 dB.
Ukukhusela kunye nokuQhosha:
Iinkqubo zomkhosi/zezonyango zifake iikheyiji zeFaraday kunye nezinzwa zokuhamba ukuthintela ukuvezwa ngengozi.
3. Izicelo zeHlabathi lokwenyani
| Imeko | Umlinganiselo woKhuseleko | Inqanaba lomngcipheko |
|---|---|---|
| Izikhululo zesiseko se-5G | Ukulungisa imisebe kuthintela ukuvezwa ebantwini | Iphantsi |
| Irada yesikhululo seenqwelo-moya | Iindawo ezingabandakanywanga ezibiyelweyo | Ayinamsebenzi |
| Imifanekiso yezonyango | Ukusebenza okutyhalwayo (<1% umjikelo womsebenzi) | Ilawulwa |
Isiphelo: Ii-antenna ze-microwave zikhuselekile xa zithobela imida yemithetho kunye noyilo olufanelekileyo. Kwii-antenna ezifumana inzuzo ephezulu, gcina umgama ongaphezulu kwe-5m ukusuka kwiindawo ezisebenzayo. Soloko uqinisekisa ukusebenza kakuhle kwee-antenna kunye nokukhusela phambi kokuba zisetyenziswe.
