Akụkọ - Ịghọta Antennas Opi nke Gburugburu: Ụkpụrụ, Uru, na Ngwa

A Okirikiri Polarization mpi Antennabụ ụdị antenna microwave pụrụ iche nke e mere iji gbasaa ma ọ bụ nata ebili mmiri electromagnetic nwere polarization gburugburu. N'adịghị ka polarization linear, ebe ubi eletriki na-agbagharị n'otu ụgbọelu, polarization gburugburu nwere vektọ ubi eletriki nke na-agbagharị mgbe niile ka ebili mmiri na-agbasa, na-achọpụta usoro helical. Njirimara pụrụ iche a na-enye uru dị ukwuu na gburugburu nkwukọrịta na mmetụta dị iche iche siri ike.

Uru Dị Mkpa nke Polarisation Gburugburu

1. Mgbochi Mgbochi na Mbelata nke Polarization

N'ime sistemụ polarization nke dị larịị, a ga-ahazi antenna nnyefe na nke nnata nke ọma n'ime oghere polarization ha iji zere mfu mgbaàmà. Polarization nke dị gburugburu na-ewepụ ihe a chọrọ. Ebili mmiri nke nwere polarization gburugburu na-ejigide ike mgbaama na-agbanwe agbanwe n'agbanyeghị ntụzịaka nke antenna nnata - uru dị oke mkpa maka nkwukọrịta satịlaịtị mkpanaka, ebe mmegharị ụgbọala na-agbanwe àgwà antenna mgbe niile.

2. Mbelata Ntụnye Aka nke Ọtụtụ Ụzọ

Mgbe ebili mmiri gbara okirikiri na-egosipụta n'elu ala (dịka mmiri, ụlọ, ma ọ bụ ala), aka polarization ya na-agbanwe agbanwe (dịka ọmụmaatụ, aka nri na-aghọ aka ekpe). Anata antenna ndị e mere maka otu aka na-ajụ aka dị iche, na-akagbu akara ngosi ndị na-eme ka ọtụtụ ụzọ daa. Ihe onwunwe a bara uru na ndị nnata GPS na njikọ nkwukọrịta obodo.

3. Mbanye site na Mmetụta Ikuku

Mgbasa okirikiri na-egosipụta nguzogide dị elu megide ntụgharị Faraday—ihe a na-ahụ ebe magnetik nke ụwa na-agbagharị mbara igwe nke ebili mmiri ndị nwere polarized n'usoro na-agafe na ionosphere. Site na iwepụ mmetụta na ntụgharị polarization, mgbasa okirikiri na-eme ka nnyefe mgbaàmà kwụsiri ike na njikọ satịlaịtị-site na ala na nkwukọrịta oghere miri emi.

4. Arụmọrụ Kachasị Mma n'Ihu Igwe Na-adịghị Mma

Mmiri ozuzo, igirigi, na snow na-ebelata ebili mmiri ndị nwere polarization gburugburu ma e jiri ya tụnyere polarization linear na ugboro ole ụfọdụ, na-eme ka polarization gburugburu bụrụ nhọrọ kachasị mma maka sistemụ radar na njikọ nkwukọrịta na-arụ ọrụ na mpaghara nwere oke mmiri ozuzo.

Mmejuputa Antenna Opi

A na-enwetakarị polarization okirikiri na antenna mpi site na polarizers agbakwunyere - usoro igwe dịka dielectric slabs, corrugations, ma ọ bụ septum polarizers nke dị n'ime nri waveguide. Ihe ndị a na-agbanwe ntinye polarized n'usoro ka ọ bụrụ mmepụta polarized gburugburu nwere ịdị ọcha dị elu na obere mfu ntinye.

Ngwa Ndị A Na-ahụkarị

•Nkwukọrịta Satellite: Ọdụ ala na antenna ndị nwere oghere na-adabere na polarization gburugburu iji nọgide na-enwe nkwụsi ike njikọ n'agbanyeghị mmegharị satellite na mmetụta ikuku.

• Sistemụ Satịlaịtị Navigation zuru ụwa ọnụ (GNSS): GPS, BeiDou, na Galileo na-eji okirikiri polarization iji hụ na e nwere ebe a pụrụ ịtụkwasị obi n'ọgba mmiri obodo na gburugburu ebe bara ụba n'ọtụtụ ụzọ.

• Sistemụ Rada ： Rada ihu igwe na radar nlekota ihe mgbaru ọsọ na-erite uru site na ikike polarization gburugburu iji mata ọdịiche dị n'etiti ihe mkpofu mmiri ozuzo na ihe mgbaru ọsọ ezi.

•Agha na Nnyocha Eletrọniki: Mgbasa gburugburu na-eme ka ikike nkwụsịtụ sie ike n'agbanyeghị ọnọdụ polarization nke akara ebumnuche.

•Nnyefe Ike RFID na Ikuku: Na-ahụ na nkwukọrịta na-aga n'ihu na mkpado na nhazi enweghị usoro.

Antenna opi okirikiri nke polarization na-anọchite anya teknụzụ tozuru oke mana na-agbanwe agbanwe mgbe niile, na-enye ike na-enweghị atụ na gburugburu ebe mgbasa ozi n'ụwa n'ezie.RFMiso, anyị na-ejikọta injinia ziri ezi na njikwa polarization dị elu iji nye ngwọta arụmọrụ dị elu nke ahaziri maka ngwa ndị kacha achọ na mbara igwe, nchekwa, na nkwukọrịta.
