Kwiinkqubo zonxibelelwano ze-microwave, inzuzo ye-eriyali sisalathisi esibalulekileyo sokulinganisa ukusebenza kwemitha. Njengengcalimicrowave antenna umthengisi, sikuqonda kakuhle ukubaluleka kokubala ngokuchanekileyo kunye nokulinganisa inzuzo ye-eriyali yokuphucula inkqubo. Eli nqaku liza kuthatha i40GHz i-eriyalikwayeI-antenna yeCassegrainnjengemizekelo yokwazisa ngokweenkcukacha indlela yokubala kunye namanqaku asebenzayo okuzuza kwe-eriyali.
1. Isiseko sokubala ngethiyori
Ukuzuza kwe-antenna (dBi) kumiselwa ngokuthe ngqo kunye nokusebenza kakuhle:
Ukuzuza (dBi) = ulwalathiso × ukusebenza kakuhle
1. Ubalo oluthe ngqo:
Ukufunyaniswa ngokudibanisa ipateni ye-radiation, i-antennas ephezulu-directivity (njenge-Cassegrain antennas) inokugxininisa amandla kwi-beam emxinwa.
2. Iingqwalasela zocikizeko:
Le miba ilandelayo yelahleko kufuneka iqwalaselwe:
-Ilahleko yokondla (okufana nokungahambelani komthwalo wamaza)
- Ilahleko yezinto eziphathekayo
- Ukuchaneka kokulungiswa komphezulu
2. Iindlela zokulinganisa zobungcali
1. Indlela yokuvavanya yokuthelekisa:
Thelekisa i-eriyali ephantsi kovavanyo (efana ne-eriyali ye-40GHz) kunye ne-eriyali esemgangathweni yokuzuza.
2. Uvavanyo olukude:
Ukulinganisa ipateni yemitha kwi-microwave darkroom, eyindlela yovavanyo lobuchwephesha edla ngokusetyenziswa **ngababoneleli be-eriyali**.
3. Uvavanyo lomhlalutyi womnatha:
Vavanya ilahleko yembuyekezo kunye nokusebenza kakuhle kwemitha ngokusebenzisa uhlalutyo lweparamitha ye-S.

I-Waveguide ukuya kwi-Coaxial Adapter (26.5-40GHz)
Waveguide Probe Antenna(26.5-40GHz)
RFmisoIimveliso ze-Antenna ze-40Ghz
3.Iteknoloji yokuqinisekisa ukulinganisa
Sebenzisa isoftware yokulinganisa i-electromagnetic enjengeHFSS kunye neCST:
- Bala ngokuchanekileyo i-eriyali yokuvula (ingakumbi ibaluleke kakhulu **i-eriyali ye-Cassegrain ** kunye nezinye ii-eriyali ezibonisayo)
- Hlalutya ulungelelwaniso lwefidi
-Vavanya ifuthe le **umkhombandlelalayisha**
4. Amanqaku aphambili omsebenzi wobunjineli
1. Iimpawu zokuphindaphinda:
Ukuzuza kwe-antenna kunolungelelwaniso olubalulekileyo lwefrikhwensi (efana nokuzuza kwe-eriyali ye-40GHz kuya kuncipha kwi-30GHz).
2. Imiba yokusingqongileyo:
Indawo yokufakela, ukuphazamiseka okujikelezayo, njl.njl. kuya kuchaphazela ukusebenza kwenzuzo yokwenene.
3. Iimfuno zenkqubo:
Ukuchaneka komatshini kuqinisekisa ukuba uyilo lwethiyori lunokuphunyezwa.
I-Antenna yeCassegrain (26.5-40GHz)
Iingcebiso zobungcali:
Kwiimfuno ezikhethekileyo ezifana ne- ** 40GHz i-antenna ** kwi-millimeter wave band okanye ** i-antenna ye-Cassegrain ** enenzuzo ephezulu, kucetyiswa ukusebenzisana nochwephesha ** umthengisi we-antenna ye-microwave ** kunye nobuchule obupheleleyo bokuvavanya ukuqinisekisa ukusebenza kwemveliso.
Si:
- Gqibezela igumbi lovavanyo
