Umgomo wokusebenza kanye nezinzuzo zama-antenna we-logarithmic periodic
I-antenna ye-log-periodic iyi-antenna enamabhendi abanzi umgomo wayo wokusebenza ususelwa 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 ejwayelekile ye-coaxial isetshenziswa njengomugqa we-microwave coaxial. Leli fomu locingo ngokuvamile linamakhondaktha amabili asesimweni esiyisilinda eduze kwe-eksisi evamile.
