- Chii chakanakira antenna?
Antennakuwana kunoreva chiyero chesimba resimba rechiratidzo chinogadzirwa neantenna chaiyo uye yakanakira radiating unit panzvimbo imwechete muchadenga pasi pemamiriro esimba rekupinza rakaenzana. Iyo inotsanangura zvakanyanya dhigirii iro antenna inopenya simba rekuisa nenzira yakatarisana. Iko kuwana kuri pachena kwakabatana neiyo antenna pateni. Iyo yakatetepa iyo huru lobe ye pateni uye iyo diki yedivi lobe, inowedzera kuwana. Kuwana kweAntenna kunoshandiswa kuyera kugona kweiyo antenna kutumira uye kugamuchira masaini munzira yakati. Ndiyo imwe yeakanyanya kukosha paramita yekusarudza base station antennas.
Kazhinji kutaura, kuvandudzwa kwekuwana kunonyanya kutsamira pakudzikisa upamhi hwedanda remwaranzi yakatwasuka uchichengetedza omnidirectional radiation kuita mundege yakachinjika. Kuwana kweAntenna kwakakosha zvakanyanya kumhando yekushanda kwenharembozha yekutaurirana masisitimu nekuti inotaridza mwero wechiratidzo kumucheto kwesero. Kuwedzera bhenefiti kunogona kuwedzera kufukidzwa kwetiweki mune imwe nzira, kana kuwedzera iyo yekuwana margin mukati meimwe siyana. Chero cellular system inzira mbiri. Kuwedzera kuwana kweantenna kunogona panguva imwe chete kuderedza kuwana bhajeti muganho weiyo nzira mbiri. Uye zvakare, iwo ma paramita anomiririra kuwana antenna ndeye dBd uye dBi. dBi ndiko kuwana kunoenderana nenzvimbo inotangira antenna, uye mwaranzi kumativi ese akafanana; dBd ine hukama nekuwana kweiyo symmetrical array antenna dBi=dBd+2.15. Mumamiriro ezvinhu mamwe chetewo, kuwedzera kwemhindu, ndiko kureba kunoita masaisai eredhiyo kuparadzira.
Antenna kuwana mufananidzo
Paunenge uchisarudza kuwana antenna, inofanirwa kutariswa zvichienderana nezvinodiwa zveiyo chaiyo application.
- Kukurukurirana kure-kupfupi: Kana chinhambwe chekutaura chiri chipfupi uye pasina zvipingamupinyi zvakawanda, kuwana antenna kwakakwira kungasadikanwa. Muchiitiko ichi, kuwana yakaderera (senge0-10dB) inogona kusarudzwa.
RM-BDHA0308-8(0.3-0.8GHz,8 Typ.dBi)
Nhaurirano yepakati-yepakati: Kutaurirana kure-kure, kuwana pakati nepakati antenna inogona kudikanwa kutsiva iyo chiratidzo chekumisikidza Q inokonzerwa nefambo yekufambisa, uchifungawo zvipingamupinyi zviri munharaunda. Muchiitiko ichi, kuwana antenna kunogona kuiswa pakati10 uye 20 dB.
RM-SGHA28-15(26.5-40 GHz ,15 Typ. dBi )
Kukurukurirana kure-kure: Kune mamiriro ekutaurirana anoda kuvhara madaro akareba kana kuva nezvipingamupinyi zvakawanda, kuwana antenna kwakakwirira kunogona kudikanwa kuti ipe simba rechiratidzo rakakwana kukunda matambudziko echinhambwe chekufambisa uye zvipingamupinyi. Muchiitiko ichi, kuwana antenna kunogona kuiswa pakati 20 uye 30 dB.
RM-SGHA2.2-25(325-500GHz,25 Typ. dBi)
Yakakwira-ruzha nharaunda: Kana paine kupindira kwakawanda uye ruzha munzvimbo yekutaurirana, antenna akakwira anogona kubatsira kuvandudza chiratidzo-ku-ruzha reshiyo nekudaro kuvandudza kunaka kwekutaurirana.
Zvinofanira kucherechedzwa kuti kuwedzera antenna kuwana kunogona kuperekedzwa nezvibayiro mune zvimwe zvinhu, senge antenna kutungamira, kufukidza, mutengo, nezvimwe. mamiriro ezvinhu. Iyo yakanakisa tsika ndeyekuita bvunzo dzemumunda kana kushandisa simulation software yekuongorora mashandiro pasi peakasiyana ekuwana kukosha kuti uwane yakanyatsokodzera pfuma yekumisikidza.
Kuti udzidze zvakawanda nezve antennas, ndapota shanya:
