Umholi-mw | Isingeniso se-Ultra Wideband Omnidirectional Antenna |
Sethula i-leader microwave tech.,(umholi-mw)i-antenna entsha ye-ultra-wideband omnidirectional ANT0104. Le antenna enamandla yakhelwe ukuthi isebenze ebangeni elibanzi ukusuka ku-20MHz ukuya ku-3000MHz, iyenze ifanelekele izinhlelo zokusebenza ezahlukahlukene ezihlanganisa ukuxhumana okungenantambo, amasistimu e-radar nokunye.
Inzuzo enkulu yale antenna inkulu kuno-0dB, futhi ukuchezuka okuyindilinga okuphezulu kungu-±1.5dB, okuqinisekisa ukudluliswa kwesignali okuthembekile nokungaguquguquki. Ukusebenza kwayo kuthuthukiswa futhi ngephethini yemisebe evundlile engu ±1.0dB, ehlinzeka ngokufaka okuhle kakhulu kuzo zonke izinhlangothi.
I-ANT0104 inezici ze-polarization eziqondile, okuyenza ilungele izinhlelo zokusebenza lapho ukudluliselwa okuqondile kukhethwa khona. Ukwengeza, i-VSWR ye-antenna ≤2.5:1 kanye ne-50 ohm impedance ihlinzeka ngokulingana kokuphazamiseka okuphelele nokulahlekelwa kwesignali okuncane.
Ukwakheka kwayo okuhlangene nokumangelengele kuyenza ilungele ukusetshenziswa kwangaphakathi nangaphandle, futhi ukusebenza kwayo kwe-omnidirectional kuvumela ukuxhumana okungenamthungo kunoma iyiphi indawo.
Kungakhathaliseki ukuthi udinga ukukhulisa amandla esignali yenethiwekhi yakho engenantambo, uthuthukise ukusebenza kwesistimu yakho ye-radar, noma umane ufuna ukuqinisekisa ukuxhumana okuthembekile phezu kwebanga elibanzi lefrikhwensi, i-ANT0104 Ultra Wideband Omnidirectional Antenna iyisixazululo esiphelele.

Esilinganisweni esisebenzayo se-antenna directivity coefficient D, siyichaza kusukela kubukhulu bebanga lemisebe ye-antenna.
I-Directivity D isilinganiso sobukhulu bokuminyana bamandla aphumayo P(θ,φ) Max kuya enaluni yalo yencazelo engu-P(θ,φ)av endaweni esesifundeni esikude, futhi iyisilinganiso esingenasici esikhulu noma esilingana no-1. . Ifomula yokubala imi kanje:
Ngaphezu kwalokho, i-directivity D ingabalwa ngefomula elandelayo:
D = 4 PI / Ω _A
Empeleni, ukubala kwe-logarithmic ka-D kuvame ukusetshenziselwa ukumela inzuzo eqondisayo yothi:
D = 10 log d
Ukuqondisa okungenhla D kungahunyushwa njengesilinganiso sobubanzi be-sphere (4π rad²) ububanzi be-antenna ω _A. Isibonelo, uma i-antenna ikhanya kuphela endaweni engaphezulu ye-hemispherical futhi ububanzi bayo be-beam bungu-ω _A=2π rad², khona-ke ukuqondisa kwayo kungu:
Uma i-logarithm yazo zombili izinhlangothi zesibalo esingenhla ithathwa, inzuzo yokuqondisa ye-antenna ehlobene ne-isotropy ingatholwa. Kufanele kuqashelwe ukuthi le nzuzo ingabonisa kuphela imisebe yephethini yokuqondisa ye-antenna, kuyunithi ye-dBi, njengoba ukusebenza kahle kokudlulisela akubhekwa njengenzuzo efanelekile. Imiphumela yokubala imi kanje:
3.01 ikilasi: : dBi d = 10 log 2 impahla
Amayunithi enzuzo ye-antenna yi-dBi ne-dBd, lapho:
I-DBi: inzuzo etholwe imisebe ye-antenna ehlobene nomthombo wephoyinti, ngoba umthombo wephoyinti uno-ω _A=4π futhi inzuzo yokuqondisa ingu-0dB;
I-DBd: iyinzuzo yemisebe ye-antenna ehlobene ne-dipole ye-dipole antenna;
Ifomula yokuguqula phakathi kwe-dBi ne-dBd ithi:
2.15 ikilasi: : dBi 0 DBD impahla
