Umhlahlandlela Ophelele Wezinti Ze-Antenna: Indlela Ezisebenza Ngayo Izinti Ze-Antenna
Ama-antenna ayithuluzi lokuxhumana elivame kakhulu ezimpilweni zethu. Kodwa-ke, abantu abaningi abawaqondi ngempela, mhlawumbe bazi nje ukuthi asetshenziselwa ukudlulisa nokwamukela izimpawu. Ngeshwa, selokhu usosayensi waseRussia uPopov asungula ngempumelelo i-antenna ngo-18...Funda kabanzi -
I-AESA vs PESA: Indlela Imiklamo Yesimanje Yama-Antenna Eguqula Ngayo Izinhlelo Ze-Radar
Ukuvela ku-Passive Electronically Scanned Array (PESA) kuya ku-Active Electronically Scanned Array (AESA) kumelela intuthuko ebaluleke kakhulu kubuchwepheshe besimanje be-radar. Ngenkathi zombili izinhlelo zisebenzisa isiteringi se-elekthronikhi, izakhiwo zazo eziyisisekelo ziyahlukahluka...Funda kabanzi -
Ingabe ama-Microwave e-5G noma ama-Radio Waves?
Umbuzo ovamile ekuxhumaneni okungenantambo ukuthi ngabe i-5G isebenza ngama-microwave noma amagagasi omsakazo. Impendulo ithi: I-5G isebenzisa kokubili, njengoba ama-microwave eyi-subset yamagagasi omsakazo. Amagagasi omsakazo ahlanganisa ububanzi obuhlukahlukene bemvamisa kagesi, kusukela ku-3 kHz kuya ku-30...Funda kabanzi -
Ukuvela Kwama-Antenna Esiteshini Esiyisisekelo: Kusukela ku-1G kuya ku-5G
Lesi sihloko sinikeza isibuyekezo esihlelekile sokuvela kobuchwepheshe be-antenna yesiteshi esiyisisekelo kuzo zonke izizukulwane zokuxhumana zeselula, kusukela ku-1G kuya ku-5G. Silandelela ukuthi ama-antenna ashintshe kanjani kusukela kuma-transceivers esignali alula aba izinhlelo eziyinkimbinkimbi eziqukethe ...Funda kabanzi -
Isebenza Kanjani I-Antenna Ye-Microwave? Incazelo Yezimiso Nezingxenye
Ama-antenna e-microwave aguqula izimpawu zikagesi zibe amaza kagesi (kanye nokuphikisana nalokho) esebenzisa izakhiwo eziklanywe ngokunemba. Ukusebenza kwazo kuncike ezimisweni ezintathu eziyinhloko: 1. Imodi Yokudlulisa Ukuguqulwa Kwamaza E-Electromagnetic: Izimpawu ze-RF ezivela kumthumeli ...Funda kabanzi -
Imodi Yokusebenza ye-Antenna Ephindwe Kabili Enezimpondo Ezimbili
I-antenna yophondo olunezinhlangothi ezimbili ingadlulisa futhi yamukele amagagasi kagesi ahlukaniswe ngokuvundlile nangokuvundlile ngenkathi igcina isimo sendawo singashintshi, ukuze iphutha lokuphambuka kwesimo sesistimu libangelwe ukushintsha isikhundla se-antenna ukuze kuhlangatshezwane...Funda kabanzi -
Isimiso Sokukhetha Sosayizi We-Waveguide
Umhlahlandlela wamagagasi (noma umhlahlandlela wamagagasi) umugqa wokudlulisa ongenalutho owenziwe ngomqhubi omuhle. Uyithuluzi lokusabalalisa amandla kagesi (ikakhulukazi ukudlulisa amagagasi kagesi anama-wavelengths ngokulandelana kwamasentimitha) Amathuluzi avamile (ikakhulukazi ukudlulisa ugesi...Funda kabanzi -
Ukusetshenziswa kwe-Antenna
Ama-antenna anezinhlelo zokusebenza ezahlukahlukene emikhakheni eyahlukene, aguqula ukuxhumana, ubuchwepheshe, kanye nocwaningo. Lawa madivayisi abalulekile ekudluliseni nasekutholeni amaza kagesi, okwenza kube nokusebenza okuningi. Ake sihlole ezinye izinhlelo zokusebenza ezibalulekile ze...Funda kabanzi -
Umehluko Phakathi kwe-AESA Radar kanye ne-PESA Radar | I-AESA Radar Vs PESA Radar
Leli khasi liqhathanisa i-radar ye-AESA ne-radar ye-PESA futhi likhuluma ngomehluko phakathi kwe-radar ye-AESA ne-radar ye-PESA. I-AESA imele i-Active Electronically Scanned Array kanti i-PESA imele i-Passive Electronically Scanned Array. ● I-PESA Radar I-PESA radar isebenzisa i-commo...Funda kabanzi -
Izisekelo Zokushabalala kanye Nezinhlobo Zokushabalala Ekuxhumaneni Okungenantambo
Leli khasi lichaza izisekelo zokushabalala kanye nezinhlobo zokushabalala ekuxhumaneni okungenantambo. Izinhlobo zokushabalala zihlukaniswe ukushabalala okukhulu kanye nokushabalala okuncane (ukusabalala kokulibaziseka kwezindlela eziningi kanye nokusabalala kwe-doppler). Ukushabalala okuthe tyaba kanye nokushabalala kokukhetha imvamisa kuyingxenye yokushabalala kwezindlela eziningi...Funda kabanzi -
