Kwiinkqubo zonxibelelwano lwe-microwave, ukufumana i-antenna luphawu oluphambili lokulinganisa ukusebenza kwemitha. NjengengcaliUmthengisi we-antenna ye-microwave, siyayazi kakuhle into yokubaluleka kokubala ngokuchanekileyo nokulinganisa inzuzo ye-antenna ukuze kuphuculwe inkqubo. Eli nqaku liza kuthathaI-antenna ye-40GHzkwayeI-antenna ye-Cassegrainnjengemizekelo yokwazisa ngokweenkcukacha indlela yokubala kunye namanqaku asebenzayo okufumana i-antenna.
1. Isiseko sokubala sethiyori
Ukwanda kwee-antenna (dBi) kugqitywa yi-directivity kunye nokusebenza kakuhle:
Inzuzo (dBi) = isikhokelo × ukusebenza kakuhle
1. Ubalo lwe-Directivity:
Zifunyenwe ngokuhlanganisa ipateni yemitha, ii-antenna ezisebenzisa ulwalathiso oluphezulu (ezifana nee-antenna zeCassegrain) zinokugxila amandla kumqadi omxinwa.
2. Izinto ekufuneka ziqwalaselwe ngokusebenza kakuhle:
Ezi zinto zilandelayo zokulahlekelwa kufuneka ziqwalaselwe:
- Ukulahleka kwe-feeder (njengokungangqinelani komthwalo we-waveguide)
- Ukulahleka kwezinto eziphathekayo
- Ukuchaneka kokucubungula umphezulu
2. Iindlela zokulinganisa zobungcali
1. Indlela yovavanyo lokuthelekisa:
Thelekisa i-antenna evavanywayo (njenge-antenna ye-40GHz) ne-antenna eqhelekileyo ye-gain horn.
2. Uvavanyo olukude:
Linganisa ipateni yemitha kwigumbi elimnyama le-microwave, eliyindlela yovavanyo yobungcali esetyenziswa kakhulu ngababoneleli be-antenna**.
3. Uvavanyo lohlalutyo lwenethiwekhi:
Vavanya ilahleko yokubuya kunye nokusebenza kakuhle kwemitha ngokusebenzisa uhlalutyo lwe-S parameter.
I-Antenna yeBroadband Horn(18-40GHz)
Isikhokelo se-Waveguide ukuya kwi-Coaxial Adapter (26.5-40GHz)
I-Antenna yeProbe yeWaveguide(26.5-40GHz)
RFmisoIimveliso ze-Antenna ze-40Ghz
3. Itekhnoloji yokuqinisekisa ukulinganisa
Sebenzisa isoftware yobungcali yokulinganisa i-electromagnetic efana ne-HFSS kunye ne-CST:
- Bala ngokuchanekileyo ukusebenza kakuhle kwe-aperture (ingakumbi ebaluleke kakhulu kwi-**Cassegrain antenna** kunye nezinye ii-antenna ezibonisa ukukhanya)
- Hlalutya ulungelelwaniso lwesondlo
- Vavanya impembelelo ye **isikhokelo segagasiumthwalo**
4. Amanqaku aphambili okusebenza kobunjineli
1. Iimpawu zefrikhwensi:
Ukwanda kwee-antenna kunolwalamano olubalulekileyo lwee-frequency (njengoko ukwandiswa kwe-antenna ye-40GHz kuya kuncipha kwi-30GHz).
2. Izinto ezichaphazela okusingqongileyo:
Indawo yokufakelwa, ukuphazamiseka okujikelezileyo, njl.njl. kuya kuchaphazela ukusebenza kwenzuzo yokwenyani.
3. Iimfuno zenkqubo:
Umatshini wokulungisa ngokuchanekileyo uqinisekisa ukuba uyilo lwethiyori lunokuphunyezwa.
I-Antenna yeCassegrain (26.5-40GHz)
Iingcebiso zobungcali:
Kwiimfuno ezikhethekileyo ezifana ne-antenna ye-**40GHz** kwi-millimeter wave band okanye i-**Cassegrain antenna** ene-gain ephezulu, kuyacetyiswa ukuba usebenzisane nomthengisi we-**microwave antenna oqeqeshiweyo** onezakhono zokuvavanya ngokupheleleyo ukuqinisekisa ukusebenza kwemveliso.
Si:
- Igumbi lovavanyo elipheleleyo
- Iqela lokulinganisa leengcali
- Amava obunjineli atyebileyo
