| Umuyobozi-mw | Intangiriro kuri Antena ya Ultra Wideband Omnidirectional |
Tubagezaho ikoranabuhanga rishya rya microwave (leader-mw) ANT0104. Iyi antene ikomeye yagenewe gukora ku ntera nini kuva kuri 20MHz kugeza 3000MHz, bigatuma ikoreshwa mu buryo butandukanye harimo itumanaho ridafite insinga, sisitemu za radar n'ibindi.
Inyungu ntarengwa y'iyi antene iruta 0dB, kandi kuzenguruka ntarengwa ni ±1.5dB, bigatuma ikimenyetso cy'itumanaho gikwirakwira neza kandi kidahindagurika. Imikorere yayo irushaho kwiyongera bitewe n'imiterere y'imirasire itambitse ya ±1.0dB, itanga ubwiza bwiza mu mpande zose.
ANT0104 ifite imiterere ya polarization ihagaze, bigatuma iba nziza cyane mu bikorwa aho kohereza imiterere ihagaze ari byo byiza. Byongeye kandi, impedance ya antene ya VSWR ≤2.5:1 na impedance ya 50 ohm itanga uburyo bwiza bwo guhuza impedance no gutakaza ikimenyetso gito.
Imiterere yayo mito kandi ikomeye ituma ikoreshwa haba mu nzu no hanze, kandi imikorere yayo y’icyerekezo cyose yemerera guhuza neza ahantu hose.
Waba ukeneye kongera imbaraga z'amajwi y'umuyoboro wawe udafite umugozi, kongera imikorere ya sisitemu yawe ya radar, cyangwa ushaka gusa gutumanaho kwizerwa ku buryo bworoshye, ANT0104 Ultra Wideband Omnidirectional Antenna ni igisubizo cyiza.

| Umuyobozi-mw | Amakuru y'ikizamini |
| Umuyobozi-mw | gupima antene |
Kugira ngo dupime neza coefficient D y’ubuyobozi bw’antene, tuyisobanura dukurikije ingano y’imirasire y’antene.
Ubuyobozi D ni igipimo cy'ubucucike bw'ingufu za radiated maximum P(θ,φ) Max kugeza ku gaciro k'impuzandengo P(θ,φ)av ku gice cy'umubumbe mu karere ka kure, kandi ni igipimo kitagira ingano kiruta cyangwa kingana na 1. Formula yo kubara ni iyi ikurikira:
Byongeye kandi, ubuyobozi D bushobora kubarwa hakoreshejwe formula ikurikira:
D = 4 PI / Ω _A
Mu by’ukuri, kubara kwa logarithmike kwa D bikunze gukoreshwa mu kwerekana inyungu y’icyerekezo cya antene:
D = 10 logi d
Icyerekezo cyavuzwe haruguru D gishobora gusobanurwa nk'igipimo cy'uruhererekane rw'umurambararo w'umurambararo (4π rad²) rwa antene ω _A. Urugero, niba antene irabagirana gusa mu mwanya wo hejuru w'umurambararo kandi uruhererekane rw'umurambararo wayo rukaba ω _A=2π rad², icyo gihe icyerekezo cyayo ni:
Iyo hafashwe logarithm y'impande zombi z'ikigereranyo cyavuzwe haruguru, inyungu y'icyerekezo cya antene ugereranyije na isotropi irashobora kuboneka. Icyitonderwa ni uko iyi nyungu ishobora kugaragaza gusa imirasire y'icyerekezo cya antene, muri dBi, kubera ko ubushobozi bwo kohereza butari bwo bufatwa nk'inyungu ikwiye. Ibisubizo byo kubara ni ibi bikurikira:
Icyiciro cya 3.01: : dBi d = 10 log 2 ibikoresho
Ibice byo gukurura antene ni dBi na dBd, aho:
DBi: ni inyungu iboneka bitewe n'imirasire ya antene ugereranije n'isoko y'ingingo, kuko isoko y'ingingo ifite ω _A=4π kandi inyungu y'icyerekezo ni 0dB;
DBd: ni inyungu y'imirasire ya antene ugereranyije na antene ya dipole y'igice cy'umuraba;
Ihinduranya ry’inyuguti hagati ya dBi na dBd ni:
Icyiciro cya 2.15: : dBi 0 Ibikoresho bya DBD
