Ant0104 Ultra whanui omnidirectional antena
| Rangatira-mw | He kupu whakataki ki te Ultra whanui omnidirectional antena |
Te whakauru i te Whare Miihini Kaiharo. Ko tenei antenna kaha e hangaia ana hei whakahaere i te whānuitanga whanui mai i te 20MHz ki te 3000MZ ki te 3000MHZ ki te 3000MHZ, e tika ana mo te maha o nga tono mo nga tono ahokore, nga punaha radar me etahi atu.
Ko te hua nui o tenei antena he nui ake i te 0DB, me te huringa nui o te rahinga ko te ± 1, 1.5db, kia tau ai te tuku tohu me te whakarite. Ko tana mahinga ka tino whakareihia ake e te tauira radiation whakarakei 1.0db, e whakarato ana i te kapi katoa i nga ahunga katoa.
Ko te ant0104 he tohu mo te poutoa, he pai ki te tono kei te pai te tuku poutū. Hei taapiri, ko te Vswr ≤2.5: 1 me te 50 ohm te kino e whakaatu ana i te riterite tino pai me te iti o te tohu tohu.
Ko tana hoahoa taapiri me te haehae e tika ana mo te whakamahi o roto, o waho hoki, me tana mahi omnidirectional e taea ai mo te hononga honohono i roto i tetahi taiao.
Ahakoa me whakapiki ake koe i te kaha tohu o to whatunga ahokore, whakarei ake i te mahinga o to punaha radar, me te hiahia noa ranei ki te whakarite i nga whakawhitiwhiti pono i roto i te whānuitanga whanui.

Mo te mehua whaihua o te whanonga Antenna e tino pai ana d, ka tautuhia e maatau mai i te rahi o te radiation antena.
Ko te whakahoahoa D ko te ōwehenga o te mana nui o te kaha p (θ, φ) ki tana uara P (θ, φ) AV i runga i te rohe o te waahi o te whenua.
I tua atu, ka taea te tatau i te tātai D e whai ake nei:
D = 4 pi / ω _a
I roto i te mahi, ko te tatauranga o te Logarithmic e whakamahia ana hei tohu mo te painga o te antena:
D = 10 Takiuru D
Ko te tikanga o runga ake ka taea te whakamaori i te ōwehenga o te awhiawhi (4π Rad²) Antenna Beach ω _a. Hei tauira, ki te huri noa i te antena anake ki te waahi iti o runga me tona waahanga kurupae ko ω _a = 2π Rad², ko te kaupapa whakahaere ko:
Mena ka tangohia te Logarithm o nga taha e rua o runga ake nei, ka taea te whiwhi i te kaha o te antenna ki a Itotropy. Me tohuhia ko tenei hua ka whakaatu anake i te tauira o te antenna, i te waahanga o te DBI, i te mea kaore i te whakaarohia te whaihua whakawhiti hei painga pai. Ko nga hua tatauranga e whai ake nei:
3.01 Akomanga:: DBI D = 10 Takiuru 2
Ko nga waeine antena he DBI me DBD, kei hea:
DBI: Ko te taonga i riro mai i te radiation antena e pa ana ki te punanga tohu, na te mea ko te puna take he _a = 4π me te taonga o te kaupapa ko te 0DB;
DBD: Ko te hua o te radiation antena e pa ana ki te hawhe-ngaru antenna;
Ko te tauira faafariunga i waenga i te DBI me DBD ko:
2.15 Akomanga:: DBI 0 Nga Rau DBD
