Ezinhlelweni zokuxhumana ze-microwave, ukuzuza kwe-antenna kuyinkomba ebalulekile yokulinganisa ukusebenza kwemisebe. Njengochwephesheumphakeli we-antenna ye-microwave, sikwazi kahle ukubaluleka kokubala ngokunembile kanye nokulinganisa inzuzo ye-antenna ukuze kuthuthukiswe uhlelo. Lesi sihloko sizothathaI-antenna engu-40 GHzfuthiI-Cassegrain antennanjengezibonelo zokwethula ngokuningiliziwe indlela yokubala kanye namaphuzu asebenzayo okuzuza kwe-antenna.
1. Isisekelo sokubala sethiyori
Ukuzuza kwe-antenna (dBi) kunqunywa ukuqondisa nokusebenza kahle:
Inzuzo (dBi) = ukuqondisa × ukusebenza kahle
1. Ukubala okuqondile:
Atholwe ngokuhlanganisa iphethini yemisebe, ama-antenna aqondiswe kakhulu (njengama-antenna e-Cassegrain) angagxilisa amandla ensimbini encane.
2. Ukucatshangelwa kokusebenza kahle:
Izinto ezilandelayo zokulahlekelwa zidinga ukucatshangelwa:
- Ukulahleka kwe-Feeder (njengokungafani komthwalo we-waveguide)
- Ukulahlekelwa Material
- Surface processing ukunemba
2. Izindlela zokulinganisa zochwepheshe
1. Indlela yokuhlola yokuqhathanisa:
Qhathanisa uthi olungaphansi kokuhlolwa (njenge-antenna engu-40GHz) nothi olujwayelekile lwephondo lokuzuza.
2. Ukuhlolwa kwenkundla ekude:
Linganisa iphethini yemisebe ku-microwave darkroom, okuyindlela yokuhlola yobungcweti evame ukusetshenziswa **abahlinzeki bezimpondo**.
3. Ukuhlolwa kokuhlaziya inethiwekhi:
Linganisa ukulahlekelwa kwembuyiselo nokusebenza kahle kwemisebe ngokuhlaziywa kwepharamitha engu-S.
I-Broadband Horn Antenna(18-40GHz)
I-Waveguide eya ku-Coaxial Adapter (26.5-40GHz)
I-Waveguide Probe Antenna(26.5-40GHz)
RFmisoImikhiqizo ye-Antenna engu-40Ghz
3.Ubuchwepheshe bokuqinisekisa ukulingiswa
Sebenzisa isoftware yokulingisa esebenza ngogesi efana ne-HFSS ne-CST:
- Bala ngokunembile ukuvuleka (okubaluleke kakhulu ku-**Cassegrain antenna** nezinye izimpondo ezibonisa ukukhanya)
- Hlaziya ukuhleleka kwesiphakeli
- Linganisa umthelela **i-waveguidelayisha**
4. Amaphuzu abalulekile omkhuba wobunjiniyela
1. Izici zokuvama:
Ukuzuza kwe-antenna kunokuhlobana okubalulekile kwemvamisa (okufana nokuzuzwa kwe-antenna engu-40GHz kuzokwehla ngo-30GHz).
2. Izici zemvelo:
Indawo yokufaka, ukuphazamiseka okuzungezile, njll. kuzothinta ukusebenza kwenzuzo yangempela.
3. Izidingo zokucubungula:
Ukunemba kwemishini kuqinisekisa ukuthi umklamo wetiyori ungafezeka.
I-Cassegrain Antenna (26.5-40GHz)
Iseluleko sochwepheshe:
Ngezidingo ezikhethekile ezifana ne-**40GHz antenna** kubhendi yegagasi eyimilimitha noma **i-antenna ye-Cassegrain** enenzuzo ephezulu, kunconywa ukusebenzisana nomhlinzeki ochwepheshe **we-microwave antenna** onekhono lokuhlola eliphelele ukuze kuqinisekiswe ukusebenza komkhiqizo.
Sine:
- Qedela igumbi lokuhlola
- Ithimba lokulinganisa lochwepheshe
- Isipiliyoni sobunjiniyela esicebile
Ukuze uthole izixazululo ezengeziwe zokuzuza i-antenna, sicela ukhululeke ukuxhumana nethimba lethu lezobuchwepheshe.
Ukuze ufunde kabanzi ngama-antenna, sicela uvakashele:
