Mbiri ya antenna ya nyanga yozungulira yokhala ndi polarized

Antena ya nyanga yozungulira yokhala ndi polarized horn ndi mtundu wofunikira wa antena yokhala ndi ntchito zosiyanasiyana, kuphatikizapo kulumikizana, radar, kulumikizana ndi satellite ndi muyeso wa wailesi. Izi ndi chiyambi cha mbiri yakale cha antena ya nyanga yozungulira yokhala ndi polarized horn:

Kuyambira kumapeto kwa zaka za m'ma 1940 mpaka kumayambiriro kwa zaka za m'ma 1950, lingaliro ndi kapangidwe ka ma antenna a nyanga ozungulira okhala ndi polarized horn anayamba kuonekera. Panthawiyi, mainjiniya a ma antenna anayamba kuzindikira kuti ma antenna achikhalidwe okhala ndi polarized linearly anali ndi zolepheretsa pa ntchito zina. Choncho, anayamba kufufuza ndi kufufuza lingaliro la ma antenna ozungulira okhala ndi polarized kuti akwaniritse bwino kutumiza ma signal ndi kulandira ma signal.

Mu 1958, Paul G. Montgomery, mainjiniya ku Radar Systems Corporation ku United States, adapanga antenna ya horn yokhala ndi mawonekedwe ozungulira, yotchedwa Montgomery Antenna. Iyi inali njira yoyamba yogwirira ntchito bwino ya antenna ya horn yozungulira ndipo idakopa chidwi cha anthu ambiri komanso kafukufuku.

M'zaka makumi otsatira, ma antenna a nyanga yozungulira yokhala ndi polarized afufuzidwa kwambiri ndipo apangidwa. Mainjiniya achita kafukufuku wambiri komanso kusanthula kwa chiphunzitso popanga ndi kukonza kapangidwe ndi magwiridwe antchito a ma antenna a nyanga yozungulira yokhala ndi polarized.

M'zaka za m'ma 1960, ma antenna a nyanga yozungulira ankagwiritsidwa ntchito kwambiri m'munda wolumikizirana. Ubwino wa antenna ya nyanga yozungulira ndi wakuti imatha kufalitsa bwino zizindikiro komanso kuteteza kusokoneza, ndipo ndi yoyenera makamaka m'malo ofalitsa njira zambiri m'makina olumikizirana opanda zingwe.

M'zaka za m'ma 1980 ndi 1990, ndi kupita patsogolo kwa kulumikizana kwa satellite ndi ukadaulo wa radar, kuchuluka kwa ma antenna a horn ozungulira polarized kunakulitsidwa kwambiri. Ma antenna a horn ozungulira polarized amagwiritsidwa ntchito kwambiri m'malo olumikizirana a satellite, machitidwe a radar, komanso m'mabwalo ankhondo ndi ndege.

Chifukwa cha kupita patsogolo kosalekeza kwa ukadaulo wamagetsi, kapangidwe ndi njira zopangira ma antenna a nyanga yozungulira yokhala ndi polarized horn nawonso asintha. Ma antenna amakono okhala ndi polarized horn amagwiritsa ntchito zipangizo zamakono komanso njira zopangira kuti apereke ma frequency apamwamba ogwirira ntchito, magwiridwe antchito abwino komanso kukula kochepa.

Kodi antenna yozungulira yokhala ndi polarized horn imagwira ntchito bwanji?

Ma antenna ozungulira okhala ndi polarized horn amakhala ndi ma radiation ozungulira okhala ndi polarized makamaka kudzera mu geometry yawo yapadera ndi kapangidwe kawo. Mfundo yogwirira ntchito ya antenna iyi imachokera pa zinthu zofunika izi:

Mawonekedwe a nyanga: Ma antenna a nyanga ozungulira nthawi zambiri amakhala ndi mawonekedwe a radiator ofanana ndi nyanga. Kapangidwe ka antenna ya nyanga kumapangitsa kuti chizindikirocho chifalikire mkati mwa nyanga, motero amapanga mawonekedwe enaake a radiation omwe angakwaniritse zofunikira za polarization yozungulira.

Cholumikizira chopingasa: Cholumikizira chapadera chopingasa nthawi zambiri chimayikidwa mkati mwa antenna ya horn kuti chigwirizane ndi zigawo zamagetsi zopingasa ndi zoyima ndi kusiyana kwa gawo la madigiri 90. Kapangidwe kameneka kamalola antenna kupanga mawonekedwe ozungulira a radiation polarized.

Ma radiation amitundu yambiri: Kapangidwe ka antenna yozungulira yokhala ndi polarized horn kamathandiza kuti iwonetse mitundu yosiyanasiyana ya ma electromagnetic fields nthawi imodzi, kuphatikizapo zizindikiro zozungulira zokhala ndi polarized zomwe zimazungulira mbali zosiyanasiyana za polarization.

Pakadali pano, ma antenna a nyanga ozungulira amagwiritsidwa ntchito kwambiri pazochitika zosiyanasiyana, kuphatikizapo kulumikizana ndi satelayiti, kulumikizana ndi mafoni, kuyeza wailesi, ndege, radar, ndi ma drones.
