Ithiyori ye-Antenna - Insimu Eseduze Nensimu Ekude
Ngemva kwengxoxo yemingcele ye-antenna eyisisekelo esahlukweni esandulele, esinye isihloko esibalulekile okufanele sicatshangelwe yizindawo eziseduze nensimu kanye nezindawo ezikude ze-antenna. Ukuqina kwemisebe okulinganiswe eduze ne-antenna kuhlukile kulokho okulinganiswe kude. ...Funda kabanzi -
Ithiyori ye-Antenna - Amapharamitha Ayisisekelo
Lesi sahluko sethula imingcele eyisisekelo yokuxhumana okungenantambo, okuhloswe ngayo ukunikeza ukuqonda okungcono ngendima yama-antenna ezinhlelweni zokuxhumana. Ukuxhumana okungenantambo kwenziwa ngendlela yamagagasi kagesi, okwenza kube kubalulekile ukuqeda...Funda kabanzi -
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 -
