Anter0104 Ultra Wallband Omnidirectireal Antenna
| Mtsogoleri-mw | Kuyamba kwa Ultra Greatball Omnidirectional antenna |
Kuyambitsa mtsogoleri wa Microwave Tech. Antenna wamphamvuyi amapangidwa kuti azigwira ntchito mobwerezabwereza kuchokera ku 20mhz mpaka 3000mhz, ndikupanga kukhala koyenera kugwiritsa ntchito mitundu mitundu kuphatikiza kuphatikiza ma diiltiar, ma radar ndi zina zambiri.
Kupeza kwakukulu kwa tinyanga imeneyi ndi kwakukulu kuposa 0DB, ndipo kupatuka kokhazikika ndi ± 1.5db, ndikuwonetsetsa kutumiza kodalirika komanso kosasintha. Kuchita kwake kumakulitsidwanso ndi ± 1.0db zopingasa za radiation, ndikupereka ndalama zabwino mbali zonse.
Antry0104 ali ndi mawonekedwe ofukula polandation, ndikupanga zabwino zofunsira komwe kufalitsa kozungulira ndikosankhidwa. Kuphatikiza apo, antenna's vswr ≤2.5: 1 ndi 50 ohm akuwonetsa zofananira zofananira ndi zochepa.
Kapangidwe kake ka komanso chopondera kumapangitsa kuti zikhale zoyenera kwa onse mkati mwakugwiritsa ntchito kunja komanso kugwiritsidwa ntchito kwanja, ndipo magwiridwe ake ake omnimirectional amalola kulumikizana kopanda pake kwina kulikonse.
Kaya mukufunikira kulimbikitsa mphamvu ya netiweki yanu yopanda zingwe, kapena mukungofuna kutsimikizira maulalo anu odalirika, kapena mukungofuna kuwonetsetsa kuti muchepetse magawo onse, anter00104 Wamkulu wa Omnidireal ndi yankho langwiro.

Pazomwe zimathandiza kunyamuka bwino d, timachifotokoza kuchokera ku gawo la antenna radiat.
Chigwirizano cha D ndi chiwerengero cha magetsi okwanira madontho p (θ, φ) AV ali pachigawo cha P (φ) Njira yokulirapo kuposa imodzi.
Kuphatikiza apo, kugwirizanitsa d kumatha kuwerengedwa ndi njira zotsatirazi:
D = 4 pi / ω _a
Pochita izi, kuwerengera kololowa kwa D nthawi zambiri kumangoimira phindu la antenna:
D = 10 chipika d
Kukhazikika pamwambapa D kumatha kutanthauzira ngati chiwerengero cha magawo (4π rad²²) Antenna Breen osiyanasiyana ωa. Mwachitsanzo, ngati antena amatulutsa malo okhawo
Ngati logarithm mbali zonse ziwiri za equation ikutengedwa, njira ya Antenna imalandira malangizo a Isotropy ikhoza kupezeka. Tiyenera kudziwa kuti phindu ili limangowonetsa njira yoyendetsera ma antenna, mu unit ya DBI, popeza njira yofalikitsa imawerengedwa ngati phindu labwino. Zotsatira za kuwerengera ndizotere:
3.1 kalasi:: DBI D = 10 Log 2
Antenna amapeza mayunitsi ndi DBI ndi DBD, komwe:
DBI: Kodi phindu lomwe limapezeka ndi antenna radiation wachibale ndi gwero la mfundo, chifukwa gwero limakhala ndi ω _a = 4π ndipo phindu lolowera ndi 0db;
DBD: Kodi phindu la antenna radiation wachibale ndi theka-faip Liplena;
Njira yosinthira pakati pa DBI ndi DBD ndi:
2.15 kalasi:: DBI 0 DBD Zinthu
