- Ndeipi purofiti ye antenna?
KanyangaKuwana zvinoreva chiyero chesimba rechiratidzo chinogadzirwa neantenna chaiyo uye chikamu chakanaka chekupenya panzvimbo imwe chete munzvimbo ine simba rekupinda rakaenzana. Inotsanangura huwandu hwesimba iro antenna inoburitsa simba rekupinda nenzira yakabatana. Kuwana zviri pachena kuti kwakabatana zvakanyanya nepatani yeantenna. Kana lobe huru yepateni iri diki uye lobe yedivi iri diki, kuwedzera kwekuwedzera. Kuwana kweantenna kunoshandiswa kuyera kugona kweantenna kutumira nekugamuchira masaini munzira chaiyo. Ndiyo imwe yeparameter dzakakosha pakusarudza maantena ebase station.
Kazhinji, kuvandudzwa kwegain kunonyanya kutsamira pakuderedza upamhi hwemwaranzi yakatwasuka uku uchichengetedza mashandiro emwaranzi ye-omnidirectional mu-horizontal plane. Kuwedzerwa kwe-antenna kwakakosha zvikuru kumhando yekushanda kwemasisitimu ekutaurirana enharembozha nekuti kunosarudza mwero wechiratidzo pamucheto wesero. Kuwedzera gain kunogona kuwedzera kufukidzwa kwenetwork munzira yakati, kana kuwedzera gain margin mukati meimwe range. Chero sisitimu yemasero inzira yemativi maviri. Kuwedzera gain ye-antenna kunogona kuderedza panguva imwe chete gain budget margin ye two-way system. Pamusoro pezvo, maparameter anomiririra antenna gain ndee dBd ne dBi. dBi igain inoenderana ne point source antenna, uye radiation munzira dzese yakafanana; dBd inoenderana negain ye symmetrical array antenna dBi=dBd+2.15. Pasi pemamiriro akafanana, gain yakakwira, kureba kunogona kuita mawave eredhiyo.
Dhayagiramu yekuwedzera kweantena
Pakusarudza antenna gain, inofanira kusarudzwa zvichienderana nezvinodiwa zvekushandisa kwacho.
- Kutaurirana kwedaro diki: Kana daro rekutaurirana riri pfupi uye pasina zvipingamupinyi zvakawanda, kuwedzera kwe antenna kwakakwira kungasadiwa. Muchiitiko ichi, kuwedzera kwakaderera (sekunge0-10dB) inogona kusarudzwa.
RM-BDHA0308-8（0.3-0.8GHz，8 Type.dBi）
Kutaurirana kwepakati nepakati: Pakutaurirana kwepakati nepakati, kuwedzera kweantenna kunogona kudiwa kuti kudzoreredze kudzikira kwechiratidzo Q kunokonzerwa nedaro rekutumirwa, ukuwo tichifunga nezvezvipingamupinyi zviri munharaunda. Muchiitiko ichi, kuwedzera kweantenna kunogona kuiswa pakati10 uye 20 dB.
RM-SGHA28-15(26.5-40 GHz ,15 Type. dBi )
Kutaurirana kure: Panyaya dzekutaurirana dzinoda kufukidza daro refu kana kuti dzine zvipingamupinyi zvakawanda, kuwedzera kweantenna kunogona kudiwa kuti pave nesimba rakakwana rechiratidzo kuti zvikunde matambudziko edaro rekutumira uye zvipingamupinyi. Muchiitiko ichi, kuwedzera kweantenna kunogona kuiswa pakati 20 ne30 dB.
RM-SGHA2.2-25(325-500GHz，25 Rudzi rwe dBi）
Nzvimbo ine ruzha rwakawanda: Kana paine kupindira kwakawanda uye ruzha munzvimbo yekutaurirana, ma antenna ane ruzha rwakawanda anogona kubatsira kuvandudza chiyero chesignal-to-noise uye nekudaro kuvandudza mhando yekutaurirana.
Zvinofanira kucherechedzwa kuti kuwedzera kuwedzera kwe antenna kunogona kuperekedzwa nekuzvipira mune zvimwe zvinhu, zvakaita sekutungamira kwe antenna, kufukidzwa, mutengo, nezvimwewo. Saka, pakusarudza kuwedzera kwe antenna, zvakakosha kufunga nezvezvinhu zvakasiyana-siyana uye kuita sarudzo dzakakodzera zvichienderana nemamiriro ezvinhu chaiwo. Nzira yakanakisa ndeyekuita bvunzo dzemunda kana kushandisa simulation software kuti uongorore mashandiro pasi pemhando dzakasiyana dzekuwana kuti uwane nzvimbo yakakodzera yekuwana natural gain.
Kuti udzidze zvakawanda nezve antenna, ndapota shanyira:
