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 -
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 -
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 -
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 -
Ama-Antenna e-Slotted Waveguide – Izimiso Zokuklama
Isithombe 1 sibonisa umdwebo we-waveguide ojwayelekile onezikhala, onesakhiwo se-waveguide eside nesincane esinezikhala phakathi. Lesi sikhala singasetshenziswa ukudlulisa amaza kagesi. isithombe 1. Ijiyometri ye-waveguide evame kakhulu enezikhala...Funda kabanzi -
Izilinganiso ze-Antenna
Ukulinganisa i-antenna inqubo yokuhlola nokuhlaziya ukusebenza kwe-antenna ngobuningi kanye nezici. Ngokusebenzisa imishini yokuhlola ekhethekile kanye nezindlela zokulinganisa, silinganisa inzuzo, iphethini yemisebe, isilinganiso samagagasi okuma, impendulo yemvamisa kanye nezinye izinto...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 -
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 -
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 -
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 -
Ukuvulwa okusebenzayo kwe-antenna
Ipharamitha ewusizo ebala amandla okwamukela e-antenna yindawo ephumelelayo noma ukuvulwa okusebenzayo. Ake sithi igagasi lendiza eline-polarization efanayo ne-antenna etholayo liyisigameko ku-antenna. Futhi ake sithi igagasi liya entuthwaneni...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
