Ama-antenna asetshenziswa kakhulu | Isingeniso ezinhlotsheni eziyisithupha ezahlukene zama-antenna empondo
I-antenna ye-Horn ingenye yama-antenna asetshenziswa kabanzi anesakhiwo esilula, ububanzi bemvamisa ebanzi, amandla amakhulu kanye nokuzuza okuphezulu. Ama-antenna e-Horn avame ukusetshenziswa njenge-antenna yokudla ku-radio astronomy enkulu, ukulandelela ngesathelayithi, kanye nama-antenna okuxhumana. Ngaphezu kwe-s...Funda kabanzi -
Uyawazi umehluko phakathi kwama-soft waveguides nama-hard waveguides?
Umhlahlandlela we-waveguide othambile uwumugqa wokudlulisela osebenza njenge-buffer phakathi kwemishini ye-microwave kanye ne-feeders. Udonga lwangaphakathi lomhlahlandlela we-waveguide othambile lunesakhiwo esigoqekile, esiguquguqukayo kakhulu futhi esingamelana nokugoba okuyinkimbinkimbi, ukwelula kanye nokucindezelwa. Ngakho-ke, ...Funda kabanzi -
Iyini i-antenna yophondo? Yiziphi izimiso eziyinhloko kanye nokusetshenziswa kwazo?
I-antenna yophondo iyi-antenna engaphezulu, i-antenna ye-microwave ene-cross-section eyindilinga noma engunxande lapho i-terminal ye-waveguide ivuleka kancane kancane. Iwuhlobo lwe-antenna ye-microwave esetshenziswa kakhulu. Insimu yayo yemisebe inqunywa ngobukhulu bomlomo kanye ne-propa...Funda kabanzi -

Umgomo wokusebenza kanye nokusetshenziswa kwe-antenna yophondo
Umlando wama-antenna e-horn uqala emuva ngo-1897, lapho umcwaningi womsakazo uJagadish Chandra Bose enza khona imiklamo yokuhlola yokuqala esebenzisa ama-microwave. Kamuva, u-GC Southworth noWilmer Barrow basungula isakhiwo se-antenna ye-horn yesimanje ngo-1938 ngokulandelana. Kusukela...Funda kabanzi -
Ukuhlukaniswa kwe-Antenna: Kuyini ukuhlukaniswa kwe-Antenna nokuthi Kungani Kubalulekile
Onjiniyela be-elekthronikhi bayazi ukuthi ama-antenna athumela futhi amukele izimpawu ngendlela yamagagasi amandla kagesi kagesi (EM) achazwe yizibalo zikaMaxwell. Njengakwezinye izihloko eziningi, lezi zibalo, kanye nokusabalala, izakhiwo ze-electromagnetism, kungafundwa ezigabeni ezahlukene...Funda kabanzi -
Izindlela ezine eziyisisekelo zokudla ama-antenna e-microstrip
Isakhiwo se-antenna ye-microstrip ngokuvamile siqukethe i-substrate ye-dielectric, i-radiator kanye nepuleti lomhlabathi. Ubukhulu be-substrate ye-dielectric buncane kakhulu kunobude be-wavelength. Ingqimba yensimbi encane phansi kwe-substrate ixhunywe ku-grun...Funda kabanzi -
