Nkhani - Antena ya Standard Gain Horn: Mvetsetsani Mfundo Zake Zogwirira Ntchito ndi Madera Ogwiritsira Ntchito

Antena ya gain horn yokhazikika ndi antenna yolunjika yomwe imagwiritsidwa ntchito kwambiri, yokhala ndi chinthu chotumizira ndi chinthu cholandira. Cholinga chake ndikuwonjezera phindu la antenna, kutanthauza kuti, kuyika mphamvu ya ma frequency a wailesi mbali inayake. Kawirikawiri, ma antenna a gain horn okhazikika amagwiritsa ntchito zinthu za parabolic antenna zozungulira kapena za sikweya. Malo owunikira a antenna ya parabolic amatha kuwonetsa chizindikiro cha RF chomwe chimalunjika ku focal point. Pa focal point, chinthu cholandira chimayikidwa, nthawi zambiri antenna yopindika kapena feed antenna, yomwe imayang'anira kusintha mphamvu ya ma frequency a wailesi kukhala zizindikiro zamagetsi kapena kusintha zizindikiro zamagetsi kukhala mphamvu ya ma frequency a wailesi.

Ubwino wa ma antenna a standard gain horn ndi awa:

• Kupeza phindu lalikulu
Kudzera mu kapangidwe ka zinthu zowunikira za parabolic ndi zolandirira chidwi, ma antenna a nyanga amatha kupeza phindu lalikulu. Izi zimapangitsa kuti zikhale zothandiza pazochitika zomwe zizindikiro ziyenera kutumizidwa mtunda wautali kapena kuphimba madera akuluakulu.

• Malangizo
Antena ya gain horn yodziwika bwino ndi antena yolunjika yomwe imatha kuyang'ana mphamvu ya ma frequency a wailesi mbali inayake ndikuchepetsa kutayika kwa ma signali mbali zina. Izi zimapangitsa kuti ikhale yabwino kwambiri pakugwiritsa ntchito monga kulumikizana pakati pa malo, kuyimitsa wailesi komanso kuyang'anira patali.

• Kuletsa mwamphamvu kusokoneza
Chifukwa cha momwe imayendera, antenna yodziwika bwino ya gain horn ili ndi mphamvu yayikulu yoletsa zizindikiro zosokoneza kuchokera mbali zina. Izi zimathandiza kukonza bwino kutumiza zizindikiro ndikuchepetsa mphamvu ya kusokoneza pa njira yolumikizirana.

Kawirikawiri amagwiritsidwa ntchito m'magwiritsidwe ntchito otsatirawa:

• Kuwulutsa pa wailesi
Ma antenna a gain horn wamba amagwiritsidwa ntchito m'malo owulutsira mawu kuti akweze ndikutumiza zizindikiro zamagetsi m'njira zinazake kuti apereke kufalikira kwa zizindikiro bwino.

• Njira yolumikizirana opanda zingwe
Mu njira zolumikizirana pafoni ndi ma satellite, ma antenna odziwika bwino a gain horn angagwiritsidwe ntchito ngati ma antenna a siteshoni yoyambira kapena ma antenna olandirira kuti awonjezere ubwino ndi kufalikira kwa ma signal.

• Dongosolo la radar
Antena ya nyanga ya gain horn imagwiritsidwa ntchito kwambiri mu radar systems, zomwe zimatha kutulutsa ndi kulandira zizindikiro za radar mozama, zomwe zimapangitsa kuti radar system izindikire bwino komanso kuti izindikire bwino.

•LAN yopanda zingwe
Mu makina opanda zingwe a netiweki, ma antenna okhazikika a gain horn angagwiritsidwe ntchito mu ma rauta opanda zingwe kapena malo oyambira kuti apereke mtunda wautali wotumizira ma signal komanso kufalikira bwino.
