ANT0825 0.85GHz～6GHz Antena ya Horn Yokwera Kwambiri

Antena ya nyanga ndi mtundu wa antenna ya microwave yomwe imagwiritsidwa ntchito kwambiri, yomwe ndi gawo lozungulira kapena lamakona anayi lomwe limatseguka pang'onopang'ono kwa terminal ya waveguide. Munda wake wa radiation umatsimikiziridwa ndi kukula kwa pakamwa pa nyanga ndi mtundu wa kufalikira. Pakati pawo, zotsatira za khoma la nyanga pa radiation zitha kuwerengedwa pogwiritsa ntchito mfundo ya geometrical diffraction. Ngati kutalika kwa nyanga kumakhalabe kofanana, kusiyana kwa gawo pakati pa kukula kwa pakamwa ndi mphamvu yachiwiri kudzawonjezeka ndi kuwonjezeka kwa ngodya ya nyanga, koma phindu silidzasintha ndi kukula kwa pakamwa. Ngati mukufuna kukulitsa gulu la ma frequency la speaker, muyenera kuchepetsa kuwunikira kwa khosi ndi pakamwa pa speaker; Kuwunikira kudzachepa ndi kuwonjezeka kwa kukula kwa pamwamba. Kapangidwe ka antenna ya nyanga ndi kosavuta, chithunzi chowongolera chilinso chosavuta komanso chosavuta kuwongolera, nthawi zambiri ngati antenna yapakati yolunjika. Antena za parabolic reflector horn zokhala ndi band yayikulu yama frequency, sidelobe yotsika komanso magwiridwe antchito apamwamba nthawi zambiri zimagwiritsidwa ntchito polumikizirana ndi microwave relay.
