Umgomo wokusebenza kanye nezinzuzo zama-antenna e-logarithmic periodic
I-antenna ye-log-periodic iyi-antenna ye-wide-band esimiso sayo sokusebenza sisekelwe ekuqineni kwe-resonance kanye nesakhiwo se-log-periodic. Lesi sihloko sizokwethula futhi kuma-antenna e-log-periodic avela ezicini ezintathu: umlando, isimiso sokusebenza kanye nezinzuzo ze-antenna ye-log-periodic...Funda kabanzi -
Izinhlobo ezivamile zezixhumi ze-antenna kanye nezici zazo
Isixhumi se-antenna siyisixhumi se-elekthronikhi esisetshenziselwa ukuxhuma imishini yemvamisa yomsakazo kanye nezintambo. Umsebenzi waso oyinhloko ukudlulisa amasignali emvamisa ephezulu. Isixhumi sinezici ezinhle kakhulu zokufanisa i-impedance, okuqinisekisa ukuthi ukubonakaliswa kwesignali nokulahlekelwa...Funda kabanzi -
Ukuhlukaniswa kwamagagasi endiza
I-Polarization ingenye yezici eziyisisekelo zama-antenna. Okokuqala sidinga ukuqonda i-polarization yamagagasi endiza. Ngemuva kwalokho singaxoxa ngezinhlobo eziyinhloko ze-antenna polarization. i-linear polarization Sizoqala ukuqonda i-polarization o...Funda kabanzi -
Qonda izimiso zokusebenza kanye nokusetshenziswa kwe-waveguide kuma-converter e-coaxial
I-waveguide ye-adaptha ye-coaxial iyithuluzi elisetshenziselwa ukuxhuma izinhlobo ezahlukene zemigqa yokudlulisela i-waveguide. Ivumela ukuguqulwa phakathi kwezintambo ze-coaxial kanye ne-waveguide ukuze kudluliselwe isignali kanye nokuxhumeka ezinhlelweni ezahlukene zokuxhumana ezingenantambo, izinhlelo ze-radar, i-microwave...Funda kabanzi -
Ulwazi oluyisisekelo lwemigqa ye-microwave coaxial
Ikhebula le-coaxial lisetshenziselwa ukudlulisa amandla e-RF kusuka kwelinye ichweba noma ingxenye liye kwamanye amachweba/izingxenye zesistimu. Ikhebula le-coaxial elijwayelekile lisetshenziswa njengomugqa we-microwave coaxial. Lolu hlobo lwentambo luvame ukuba nama-conductor amabili ngesimo se-cylindrical azungeze i-axis evamile. Zonke...Funda kabanzi -
Isingeniso senqubo yokukhiqiza imikhiqizo ye-RFMISO—ukubhoboza nge-vacuum
Ubuchwepheshe bokushisela nge-vacuum buyindlela yokuhlanganisa izingxenye ezimbili noma ngaphezulu zensimbi ndawonye ngokuzifudumeza emazingeni okushisa aphezulu nasendaweni yokushisela nge-vacuum. Okulandelayo yisingeniso esiningiliziwe sobuchwepheshe bokushisela nge-vacuum: I-Va...Funda kabanzi -
Idizayini yesiguquli semvamisa ye-RF-Isiguquli se-RF Up, Isiguquli se-RF Down
Lesi sihloko sichaza ukwakheka kwesiguquli se-RF, kanye nemidwebo yamabhulokhi, sichaza ukwakheka kwesiguquli se-RF kanye nokwakheka kwesiguquli se-RF downconverter. Sikhuluma ngezingxenye zemvamisa ezisetshenziswa kulesi siguquli semvamisa ye-C-band. Ukwakheka kwenziwa ebhodini le-microstrip kusetshenziswa i-discre...Funda kabanzi -
Imvamisa ye-antenna
I-antenna ekwazi ukudlulisa noma ukwamukela amaza kagesi (EM). Izibonelo zala maza kagesi zihlanganisa ukukhanya okuvela elangeni, kanye namaza atholwa yiselula yakho. Amehlo akho athola ama-antenna athola amaza kagesi kagesi endaweni ethile...Funda kabanzi -
Ukubaluleka kwama-antenna emkhakheni wezempi
Emkhakheni wezempi, ama-antenna awubuchwepheshe obubaluleke kakhulu. Inhloso ye-antenna ukwamukela nokudlulisa izimpawu zemvamisa yomsakazo ukuze kuvunyelwe ukuxhumana okungenantambo namanye amadivayisi. Ezicini zokuzivikela nezempi, ama-antenna adlala indima ebalulekile njengoba esetshenziswa...Funda kabanzi -
Ububanzi be-antenna
I-bandwidth ingenye ipharamitha ye-antenna eyisisekelo. I-bandwidth ichaza ububanzi bemvamisa i-antenna engakhipha noma yamukele amandla ngendlela efanele. Ngokuvamile, i-bandwidth edingekayo ingenye yamapharamitha asetshenziswa ukukhetha uhlobo lwe-antenna. Isibonelo, kune-m...Funda kabanzi -
Ukuhlaziywa kwesakhiwo, isimiso sokusebenza kanye nezimo zokusetshenziswa kwama-antenna e-microstrip
I-antenna ye-Microstrip iyi-antenna encane evamile, equkethe i-patch yensimbi, i-substrate kanye ne-ground plane. Isakhiwo sayo simi kanje: Ama-patch ensimbi: Ama-patch ensimbi avame ukwenziwa ngezinto eziqhuba ugesi, njengethusi, i-aluminium,...Funda kabanzi
