Izindlela zendabuko zivame ukudinga ukuxhuma ngesandla, ukujikeleza, kanye nokuxhuma kabusha i-antenna — inqubo eyethula ukuguguleka komshini, amaphutha okuqondanisa,...Funda kabanzi -
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 -
I-Antenna Ejikelezayo: Ukukhetha Okuhle Kokuhlukaniswa Kwesiyingi Se-Broadband – Kusukela Ku-Theory Kuya Kuzicelo
I-Spiral Antenna iyisibonelo esijwayelekile se-antenna yocingo, ebonakala ngesakhiwo sayo esimise okwe-spiral. Iyi-antenna ye-broadband efanelekela ama-VHF nama-UHF band. I-antenna ye-helical isebenza ngaphezu kwebanga lemvamisa elicishe libe ngu-30 MHz kuya ku-3 GHz, ikakhulukazi imboza i-V...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 -
I-Planar Spiral Antenna: Lapho i-Bandwidth Ibaluleke Ngempela
Buza noma yimuphi unjiniyela we-antenna mayelana nokusebenza kwe-wideband, futhi kungenzeka ukuthi ama-antenna ajikelezayo ajikelezayo azovela ekuqaleni kwengxoxo. Lezi zakhiwo eziyisicaba, eziyindilinga—ezinezingalo ezigobile ngaphandle njengeminwe noma umthala—ziye zaxazulula izinkinga ze-bandwidth kusukela ...Funda kabanzi -
I-Antenna Yezinhlangothi Ezimbili: Ihhashi Elisebenzayo Lezinhlelo Zokusebenza Eziqondiswe Ku-Broadband
Uma uke wangena elabhorethri yokuhlola i-EMC noma wasebenza ezinhlelweni zokuqapha i-wideband, kungenzeka ukuthi uke wahlangana ne-antenna ye-biconical. Uma uqala ukuyibuka, isimo sayo esilinganayo, esifana ne-bow-tie siyabonakala—izinto ezimbili ezi-conical zibhekene, ziphakelwa phakathi nendawo. Kodwa ngale...Funda kabanzi -
Ukuqonda Ama-Antenna Empondo E-Circular Polarization: Izimiso, Izinzuzo, kanye Nezicelo
I-Antenna Yesiyingi Se-Polarization Horn uhlobo olukhethekile lwe-antenna ye-microwave eklanyelwe ukukhipha noma ukwamukela amaza kagesi ane-polarization eyindilinga. Ngokungafani ne-polarization eqondile, lapho insimu kagesi ijikeleza khona endizeni eyodwa, i-polarization eyindilinga ifaka...Funda kabanzi -
Umhlahlandlela Ophelele Wezinti Ze-Antenna: Indlela Ezisebenza Ngayo Izinti Ze-Antenna (Ingxenye 2)
Kusukela engxoxweni yangaphambilini, yize ama-antenna eza ngezindlela eziningi nezimo, angahlukaniswa kabanzi ngokusekelwe ekufaneni. Ngokwe-wavelength: ama-antenna ane-medium-wave, ama-antenna ane-short-wave, ama-antenna ane-ultra-short-wave, ama-antenna e-microwave... Nge-perfo...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 -
Isincomo somkhiqizo we-RFMiso——I-Ka-band Dual-polarized Planar Phased Array Antenna
I-antenna ye-phased array iyisistimu ye-antenna ethuthukisiwe evumela ukuskena kwe-elekthronikhi (ngaphandle kokujikeleza komshini) ngokulawula umehluko wesigaba wezimpawu ezidluliselwa/ezamukelwe yizinto eziningi ezikhipha imisebe.
