Umgomo wobuchwepheshe befrikhwensi yerediyo isekelwe ekusabalaliseni nasekuguquleni...Funda kabanzi -
Umgomo wokuzuza kwe-antenna, indlela yokubala inzuzo ye-antenna
Ukuzuza kwe-antenna kubhekisela ekuzuzeni amandla okukhazimulayo kwe-antenna endaweni ethile ehlobene ne-antenna yomthombo wephoyinti efanelekile. Imele amandla emisebe ye-antenna ibheke ohlangothini oluthile, okungukuthi, ukwamukela isignali noma ukusebenza kahle kokukhishwa kwe-ante...Funda kabanzi -
Izindlela ezine zokuphakela eziyisisekelo zama-microstrip antenna
Ukwakheka kwe-antenna encane ngokuvamile iqukethe i-dielectric substrate, irediyetha kanye nepuleti eliphansi. Ubukhulu be-dielectric substrate buncane kakhulu kunobude be-wavelength. Ungqimba lwensimbi oluncane olungaphansi kwe-substrate luxhunywe ku-groun...Funda kabanzi -
I-Antenna Polarization: Iyini i-Antenna Polarization nokuthi Kungani Ibalulekile
Onjiniyela bama-elekthronikhi bayazi ukuthi izimpondo zithumela futhi zamukele amasignali ngendlela yamaza amandla kazibuthe kagesi (EM) achazwe izibalo zikaMaxwell. Njengezihloko eziningi, lezi zibalo, kanye nokusabalalisa, izakhiwo ze-electromagnetism, zingafundwa ngezindlela ezahlukene ...Funda kabanzi -
Isimiso sokusebenza kanye nokusetshenziswa kwe-antenna yophondo
Umlando wezimpondo zophondo uhlehlela emuva ku-1897, lapho umcwaningi womsakazo u-Jagadish Chandra Bose enza imiklamo yokuhlola eyiphayona esebenzisa ama-microwave. Kamuva, u-GC Southworth kanye noWilmer Barrow basungula ukwakheka kwe-antenna yesimanje yophondo ngo-1938 ngokulandelana. Njengoba t...Funda kabanzi -
Yini i-antenna yophondo? Yiziphi izimiso eziyinhloko kanye nokusetshenziswa?
I-antenna yophondo wuthi olungaphezulu, i-antenna ye-microwave enesiphambano esiyindilinga noma esingunxande lapho i-terminal ye-waveguide ivuleka kancane kancane. Iwuhlobo olusetshenziswa kakhulu lwe-antenna ye-microwave. Inkambu yayo yemisebe inqunywa usayizi womlomo kanye ne-propa...Funda kabanzi -
Uyawazi umehluko phakathi kwamagagasi athambile namagagasi aqinile?
I-Soft waveguide iwumugqa wokudlulisela osebenza njengesivikelo phakathi kwemishini ye-microwave nama-feeder. Udonga lwangaphakathi lwe-waveguide ethambile lunesakhiwo sikathayela, esivumelana nezimo kakhulu futhi esingakwazi ukumelana nokugoba okuyinkimbinkimbi, ukwelula nokucindezelwa. Ngakho-ke, ku...Funda kabanzi -
Ama-antenna asetshenziswa kakhulu | Isingeniso sezinhlobo eziyisithupha ezihlukene zezimpondo
I-antenna yophondo ingenye yezimpondo ezisetshenziswa kakhulu ezinesakhiwo esilula, ububanzi befrikhwensi ebanzi, umthamo wamandla amakhulu kanye nokuzuza okuphezulu. Izimpondo zophondo zivame ukusetshenziswa njengezimpondo eziphakelayo kusayensi yezinkanyezi yomsakazo wezinga elikhulu, ukulandelela ngesathelayithi, kanye nezimpondo zokuxhumana. Ngaphezu kwe-s...Funda kabanzi -
