Mbiri ndi ntchito ya ma antenna a nyanga ya koni

Mbiri ya ma antenna a tapered horn inayamba kumayambiriro kwa zaka za m'ma 1900. Ma antenna oyambirira a tapered horn ankagwiritsidwa ntchito mu ma amplifiers ndi ma speaker systems kuti akonze kuwala kwa zizindikiro za mawu. Ndi chitukuko cha mauthenga opanda zingwe, ma antenna a tapered horn amagwiritsidwa ntchito pang'onopang'ono m'ma wailesi ndi ma microwave. Ubwino wake mu kuwala kwa mafunde a electromagnetic wave ndi reception zimapangitsa kuti ikhale kapangidwe kofunikira ka antenna. Pambuyo pa zaka za m'ma 1950, ndi chitukuko chachangu cha ukadaulo wolumikizirana ndi ma microwave, ma antenna a tapered horn anayamba kugwiritsidwa ntchito kwambiri m'magawo ankhondo ndi anthu wamba. Amagwiritsidwa ntchito m'magwiritsidwe ntchito monga ma radar system, machitidwe olumikizirana, kulumikizana ndi ma satellite, muyeso wa wailesi ndi ma antenna arrays. Kapangidwe ndi kukonza bwino ma antenna a tapered horn kwalandiranso kafukufuku ndi kusintha kotsatizana. Kuyambira kusanthula koyambirira kwa chiphunzitso mpaka kuyambitsa ma simulation a manambala ndi ma algorithms optimization, magwiridwe antchito a ma antenna a tapered horn akupitilizabe kusintha. Masiku ano, antenna ya tapered horn yakhala kapangidwe ka antenna wamba komanso koyambira komwe kamagwiritsidwa ntchito kwambiri mu kulumikizana opanda zingwe ndi ukadaulo wa microwave.
Imagwira ntchito potsogolera mafunde amagetsi kuchokera kumadoko ang'onoang'ono kupita kumadoko akuluakulu kuti ipeze phindu lalikulu komanso kuyankha pafupipafupi. Pamene mafunde amagetsi alowa m'doko laling'ono la antenna ya tapered horn kuchokera ku chingwe chotumizira (monga chingwe cha coaxial), mafunde amagetsi amayamba kufalikira pamwamba pa kapangidwe ka tapered. Pamene kapangidwe ka conical kakukula pang'onopang'ono, mafunde amagetsi amafalikira pang'onopang'ono, ndikupanga dera lalikulu la radiation. Kukula kumeneku kwa geometry kumapangitsa mafunde amagetsi kutuluka m'doko lalikulu la antenna ya tapered horn. Chifukwa cha mawonekedwe apadera a kapangidwe ka cone, kusiyana kwa mafunde amagetsi m'dera la radiation ndi kochepa, motero kumapereka phindu lalikulu. Mfundo yogwirira ntchito ya antenna ya conical horn imadalira kuwunikira, kusinthasintha ndi kufalikira kwa mafunde amagetsi mkati mwa kapangidwe ka conical. Njirazi zimalola mafunde amagetsi kuti aziyang'ana ndikufalikira, zomwe zimawalola kuti atuluke bwino. Mwachidule, mfundo yogwirira ntchito ya antenna ya conical horn ndikutsogolera mafunde amagetsi kuchokera ku doko laling'ono kupita ku doko lalikulu, kukwaniritsa kuwala kwa mafunde amagetsi ndi phindu lalikulu kudzera mu kapangidwe kapadera ka geometri. Izi zimapangitsa ma antenna a tapered horn kukhala mtundu wofunikira wa antenna mu kulumikizana opanda zingwe ndi ntchito za microwave.
