Ezinhlelweni zokuxhumana ze-microwave, ukukhuphuka kwe-antenna kuyinkomba eyinhloko yokulinganisa ukusebenza kwemisebe. Njengochwephesheumhlinzeki we-antenna ye-microwave, siyazi kahle ukubaluleka kokubala nokulinganisa ngokunembile inzuzo ye-antenna ukuze kuthuthukiswe uhlelo. Lesi sihloko sizothathaI-antenna engu-40GHzfuthiI-antenna ye-Cassegrainnjengezibonelo zokwethula ngokuningiliziwe indlela yokubala kanye namaphuzu asebenzayo okuzuza kwe-antenna.
1. Isisekelo sokubala ngokwethiyori
Ukuzuza kwe-antenna (dBi) kunqunywa yisiqondiso kanye nokusebenza kahle:
Inzuzo (dBi) = isiqondiso × ukusebenza kahle
1. Ukubalwa kwesiqondiso:
Etholakala ngokuhlanganisa iphethini yemisebe, ama-antenna aqondisa phezulu (njenge-antenna ye-Cassegrain) angagxilisa amandla emsebeni omncane.
2. Izinto okufanele zicatshangelwe ngokusebenza kahle:
Izici zokulahlekelwa ezilandelayo zidinga ukucatshangelwa:
- Ukulahlekelwa kwesiphakeli (njengokungalingani komthwalo we-waveguide)
- Ukulahlekelwa yizinto ezibonakalayo
- Ukunemba kokucubungula okungaphezulu
2. Izindlela zokulinganisa zobungcweti
1. Indlela yokuhlola yokuqhathanisa:
Qhathanisa i-antenna evivinywayo (njenge-antenna engu-40GHz) ne-antenna ejwayelekile ye-gain horn.
2. Ukuhlolwa kwensimu ekude:
Linganisa iphethini yemisebe egumbini elimnyama le-microwave, okuyindlela yokuhlola yobungcweti evame ukusetshenziswa ngabaphakeli be-**antenna**.
3. Ukuhlolwa kokuhlaziya inethiwekhi:
Hlola ukulahlekelwa kokubuya kanye nokusebenza kahle kwemisebe ngokuhlaziywa kwepharamitha ye-S.
I-Antenna Yesiphondo Se-Broadband(18-40GHz)
Umhlahlandlela Wamagagasi kuya ku-Coaxial Adapter (26.5-40GHz)
I-Antenna ye-Probe ye-Waveguide(26.5-40GHz)
I-RFmisoImikhiqizo ye-Antenna engu-40Ghz
3. Ubuchwepheshe bokuqinisekisa ukulingisa
Sebenzisa isofthiwe yokulingisa kagesi yobungcweti njenge-HFSS ne-CST:
- Bala ngokunembile ukusebenza kahle kokuvula (okubaluleke kakhulu ikakhulukazi ku-**Cassegrain antenna** kanye nezinye izinti zokubonisa)
- Hlaziya ukulungiswa kokuphakelayo
- Hlola umthelela we-**umhlahlandlela wamagagasiumthwalo**
4. Amaphuzu abalulekile okusebenza kobunjiniyela
1. Izici zemvamisa:
Ukwanda kwe-antenna kunobudlelwano obukhulu bemvamisa (njengoba ukwehla kwe-antenna engu-40GHz kuzokwehla ku-30GHz).
2. Izici zemvelo:
Indawo yokufaka, ukuphazamiseka okuzungezile, njll. kuzothinta ukusebenza kwangempela kokuzuza.
3. Izidingo zenqubo:
Umshini wokulungisa kahle uqinisekisa ukuthi umklamo wethiyori ungafezeka.
I-Antenna ye-Cassegrain (26.5-40GHz)
Iseluleko sochwepheshe:
Ngezidingo ezikhethekile njenge-antenna engu-**40GHz** ku-millimeter wave band noma i-**Cassegrain antenna** ene-gain ephezulu, kunconywa ukubambisana nomhlinzeki we-**microwave antenna ochwepheshe** onamakhono okuhlola aphelele ukuqinisekisa ukusebenza komkhiqizo.
Sine:
- Igumbi lokuhlola eliphelele
- Ithimba lokulinganisa lochwepheshe
- Ulwazi lobunjiniyela olucebile
Ukuze uthole izixazululo ezengeziwe zokuthuthukisa i-antenna, sicela ukhululeke ukuxhumana nethimba lethu lobuchwepheshe.
Ukuze ufunde kabanzi ngama-antenna, sicela uvakashele:
