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 -
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 -
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 -
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 -
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 ehambisanayo noma ehambisanayo ingakhethwa ukuze kufezwe ukufaniswa kwe-impedance phakathi kwemigqa yokudlulisela noma phakathi...Funda kabanzi -
Isibonisi Sekona Esiyi-Trihedral: Ukuzindla Okuthuthukisiwe Nokudluliselwa Kwezimpawu Zokuxhumana
Isibukisi se-trihedral, esaziwa nangokuthi isibukisi sekona noma isibukisi se-triangular, siyithuluzi eliqondiwe ngokunganaki elivame ukusetshenziswa kuma-antenna kanye nezinhlelo ze-radar. Siqukethe izibukisi ezintathu ezihleliwe ezakha isakhiwo esinonxantathu esivaliwe. Lapho igagasi le-electromagnetic lishaya i-tr...Funda kabanzi -
