Ukuguqulwa kwamandla kuma-antenna e-radar
Kumasekhethi noma amasistimu e-microwave, yonke isekethe noma isistimu ivamise ukwakhiwa ngamadivayisi amaningi ayisisekelo e-microwave njengezihlungi, ama-couplers, ama-power dividers, njll. Kwethenjwa ukuthi ngalezi mishini, kungenzeka ukudlulisa kahle amandla esignali ukusuka endaweni eyodwa ukuya kwelinye. ...Funda kabanzi -
Ukufanisa i-Waveguide
Ungafinyelela kanjani ukufaniswa kwe-impedance kwama-waveguides? Kusuka kuthiyori yolayini wokudlulisa kuthiyori ye-antenna ye-microstrip, siyazi ukuthi uchungechunge olufanele noma imigqa yokudlulisa efanayo ingakhethwa ukuze kuzuzwe ukufaniswa kwe-impedance phakathi kwemigqa yokudlulisela noma phakathi kwe-transmissio...Funda kabanzi -
I-Trihedral Corner Reflector: Ukuboniswa Okuthuthukisiwe Nokudluliswa Kwezimpawu Zokuxhumana
I-trihedral reflector, eyaziwa nangokuthi i-reflector yekhona noma i-triangular reflector, iyithuluzi eliqondiwe ngokungenzi lutho elivame ukusetshenziswa kuma-antenna namasistimu e-radar. Iqukethe izibonisi ezintathu zepulani ezakha isakhiwo esivaliwe esingunxantathu. Lapho i-electromagnetic wave ishaya i-tr...Funda kabanzi -
Ukuvuleka okusebenzayo kwe-antenna
Ipharamitha ewusizo ebala amandla okwamukela othi indawo esebenzayo noma indawo esebenza kahle. Cabanga ukuthi igagasi lendiza eline-polarization efana ne-antenna eyamukelwe liyenzeka othini. Ngaphezu kwalokho cabanga ukuthi igagasi liya entuthwaneni...Funda kabanzi -
I-Slotted Waveguide Antennas - Izimiso Zokuklama
Umfanekiso 1 ubonisa umdwebo ojwayelekile we-waveguide slotted, onesakhiwo eside nesincane se-waveguide esine-slot phakathi. Lesi slot singasetshenziswa ukudlulisa amagagasi kagesi. umfanekiso 1. Ijiyomethri ye-wavegu ene-slot evame kakhulu...Funda kabanzi -
Izilinganiso ze-Antenna
Ukulinganisa kwe-antenna kuyinqubo yokuhlola kanye nokuhlaziya ukusebenza kwe-antenna nezici. Ngokusebenzisa amathuluzi okuhlola akhethekile nezindlela zokulinganisa, sikala inzuzo, iphethini yemisebe, isilinganiso samagagasi okuma, impendulo yemvamisa kanye nezinye ipharamu...Funda kabanzi -
Umgomo wokusebenza kanye nezinzuzo zama-antenna we-logarithmic periodic
I-antenna ye-log-periodic iyi-antenna enamabhendi abanzi umgomo wayo wokusebenza usekelwe ku-resonance kanye nesakhiwo se-log-periodic. Le ndatshana izokwethula futhi kuma-antenna we-log-periodic avela ezicini ezintathu: umlando, umgomo wokusebenza kanye nezinzuzo ze-anten ye-log-periodic...Funda kabanzi -
Izinhlobo ezijwayelekile zezixhumi ze-antenna nezici zazo
Isixhumi se-antenna iyisixhumi se-elekthronikhi esisetshenziswa ukuxhuma imishini yamaza omsakazo kanye nezintambo. Umsebenzi wayo oyinhloko ukudlulisa amasignali amaza aphezulu. Isixhumi sinezici ezinhle kakhulu zokuqhathanisa ne-impedance, eziqinisekisa ukuthi ukubonakaliswa kwesignali nokulahlekelwa...Funda kabanzi -
I-polarization yamaza endiza
I-polarization ingenye yezimpawu eziyisisekelo zama-antenna. Okokuqala sidinga ukuqonda i-polarization yamaza endiza. Ngemuva kwalokho singaxoxa ngezinhlobo eziyinhloko ze-antenna polarization. i-polarization yomugqa Sizoqala ukuqonda i-polarization o...Funda kabanzi -
Qonda izimiso zokusebenza kanye nokusetshenziswa kwe-waveguide kuma-coaxial converters
I-waveguide ye-adaptha ye-coaxial iyithuluzi elisetshenziselwa ukuxhuma izinhlobo ezahlukene zemigqa yokudlulisa i-waveguide. Ivumela ukuguqulwa phakathi kwezintambo ze-coaxial namagagasi okuhambisa isignali nokuxhumeka ezinhlelweni zokuxhumana ezingenazintambo ezihlukene, izinhlelo ze-radar, i-microwav...Funda kabanzi -
Ulwazi oluyisisekelo lwemigqa ye-microwave coaxial
Intambo ye-coaxial isetshenziselwa ukudlulisa amandla e-RF isuka embobeni eyodwa noma ingxenye iye kwezinye izimbobo/izingxenye zohlelo. Intambo ye-coaxial evamile isetshenziswa njengomugqa we-microwave coaxial. Leli fomu locingo ngokuvamile linamakhondaktha amabili asesimweni esiyisilinda eduze kwe-eksisi evamile.
