Ukufanisa i-Waveguide
Ungakufeza kanjani ukufaniswa kwe-impedance kwama-waveguides? Kusukela ku-theory yomugqa wokudlulisela ku-theory ye-antenna ye-microstrip, siyazi ukuthi imigqa yokudlulisela ewuchungechunge noma ehambisanayo ingakhethwa ukuze kufezwe ukufaniswa kwe-impedance phakathi kwemigqa yokudlulisela noma phakathi kwe-transmission...Funda kabanzi -
Ukuguqulwa kwamandla kuma-antenna e-radar
Kumasekethe noma izinhlelo ze-microwave, lonke isekethe noma uhlelo luvame ukwakhiwa ngamadivayisi amaningi ayisisekelo e-microwave njengezihlungi, ama-couplers, ama-power dividers, njll. Kuthenjwa ukuthi ngala madivayisi, kungenzeka ukudlulisa amandla esignali ngempumelelo kusuka endaweni eyodwa kuya ...Funda kabanzi -
Imikhiqizo ye-RFMISO Cassegrain Antenna
Isici se-antenna ye-Cassegrain ukusebenzisa i-back feed ngendlela ephumelelayo kunciphisa ukumosheka kwesistimu ye-feeder. Kuhlelo lwe-antenna olunesistimu ye-feeder eyinkimbinkimbi, sebenzisa i-antenna ye-cassegrain enganciphisa ngempumelelo umbala we-feeder. Imvamisa ye-antenna yethu ye-cassegrain...Funda kabanzi -
I-Grid Antenna Array
Ukuze uzivumelanise nezidingo ze-engeli ye-antenna yomkhiqizo omusha futhi wabelane ngesikhunta seshidi le-PCB lesizukulwane esidlule, ukwakheka kwe-antenna okulandelayo kungasetshenziswa ukufeza inzuzo ye-antenna engu-14dBi@77GHz kanye nokusebenza kwemisebe engu-3dB_E/H_Beamwidth=40°. Kusetshenziswa i-Rogers 4830 ...Funda kabanzi -
isiguquli
Njengenye yezindlela zokudla zama-antenna e-waveguide, ukwakheka kwe-microstrip kuya ku-waveguide kudlala indima ebalulekile ekudlulisweni kwamandla. Imodeli yendabuko ye-microstrip kuya ku-waveguide yile elandelayo. I-probe ephethe i-dielectric substrate futhi ephakelwa umugqa we-microstrip iku...Funda kabanzi -
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 -
