ANT0104 Ultra Wideband Omnidirectional Antenna
| Mtsogoleri-mw | Chiyambi cha Ultra Wideband Omnidirectional Antenna |
Tikubweretsa ukadaulo wa microwave watsopano (leader-mw) antenna yatsopano ya ultra-wideband omnidirectional ANT0104. Antena yamphamvu iyi idapangidwa kuti igwire ntchito pa ma frequency osiyanasiyana kuyambira 20MHz mpaka 3000MHz, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito mapulogalamu osiyanasiyana kuphatikiza kulumikizana opanda zingwe, makina a radar ndi zina zambiri.
Kuchuluka kwa antenna iyi ndi kwakukulu kuposa 0dB, ndipo kusiyana kwakukulu kwa kuzungulira ndi ±1.5dB, zomwe zimapangitsa kuti chizindikiro chifalikire bwino komanso nthawi zonse. Kugwira ntchito kwake kumakulitsidwanso ndi mawonekedwe a ±1.0dB opingasa, omwe amapereka kufalikira kwabwino mbali zonse.
ANT0104 ili ndi mawonekedwe ozungulira, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito komwe kumakonda kutumiza mozungulira. Kuphatikiza apo, VSWR ya antenna ≤2.5:1 ndi 50 ohm impedance imapereka kufananiza bwino kwa impedance komanso kutayika kochepa kwa chizindikiro.
Kapangidwe kake kakang'ono komanso kolimba kamakupangitsa kuti kagwiritsidwe ntchito mkati ndi kunja, ndipo magwiridwe ake onse amalola kulumikizana bwino kulikonse.
Kaya mukufuna kuwonjezera mphamvu ya ma signali pa netiweki yanu yopanda zingwe, kukulitsa magwiridwe antchito a radar system yanu, kapena kungofuna kuonetsetsa kuti kulumikizana kodalirika kumayendetsedwa ndi ma frequency ambiri, ANT0104 Ultra Wideband Omnidirectional Antenna ndiye yankho labwino kwambiri.

Kuti muyeze bwino antenna directionivity coefficient D, timaifotokoza kuchokera ku mulingo wa antenna radiation beam range.
Directivity D ndi chiŵerengero cha mphamvu yayikulu kwambiri yowala P(θ,φ) Max ku mtengo wake wapakati P(θ,φ)av pa bolodi m'chigawo chakutali, ndipo ndi chiŵerengero chopanda dimension chachikulu kuposa kapena chofanana ndi 1. Fomula yowerengera ndi iyi:
Kuphatikiza apo, malangizo D akhoza kuwerengedwa ndi fomula iyi:
D = 4 PI / Ω _A
Mwachizolowezi, kuwerengera kwa logarithmic kwa D nthawi zambiri kumagwiritsidwa ntchito kuyimira phindu lolunjika la antenna:
D = 10 chipika d
Malangizo omwe ali pamwambapa D akhoza kutanthauziridwa ngati chiŵerengero cha mzere wa antenna (4π rad²) ω _A. Mwachitsanzo, ngati antenna imangofikira ku malo apamwamba a hemispherical ndipo mzere wake ndi ω _A=2π rad², ndiye kuti malangizo ake ndi awa:
Ngati logarithm ya mbali zonse ziwiri za equation yomwe ili pamwambapa yatengedwa, phindu la antenna poyerekeza ndi isotropy lingapezeke. Tiyenera kudziwa kuti phindu ili limangowonetsa kuwala kwa antenna, mu unit ya dBi, popeza mphamvu yotumizira siiganiziridwa ngati phindu labwino. Zotsatira za kuwerengera ndi izi:
Kalasi ya 3.01: : dBi d = 10 log 2 zinthu
Mayunitsi opezera antenna ndi dBi ndi dBd, pomwe:
DBi: ndi phindu lomwe limapezeka ndi kuwala kwa antenna poyerekeza ndi gwero la mfundo, chifukwa gwero la mfundo lili ndi ω _A=4π ndipo phindu lolunjika ndi 0dB;
DBd: ndi phindu la kuwala kwa antenna poyerekeza ndi antenna ya half-wave dipole;
Fomula yosinthira pakati pa dBi ndi dBd ndi iyi:
Kalasi ya 2.15: : dBi 0 DBD zakuthupi
