Akụkọ ihe mere eme nke antenna mpi gbara okirikiri

Antenna opi gbara okirikiri bụ ụdị antenna dị mkpa nke nwere ọtụtụ ojiji dị iche iche, gụnyere nkwukọrịta, radar, nkwukọrịta satịlaịtị na nha redio. Ihe ndị a bụ mmalite akụkọ ihe mere eme nke antenna opi gbara okirikiri:

Site na ngwụcha afọ 1940 ruo na mbido afọ 1950, echiche na nhazi nke antenna opi gbara okirikiri malitere ịpụta. N'oge a, ndị injinia antenna malitere ịghọta na antenna ọdịnala nwere oke kwụ ọtọ nwere oke na ụfọdụ ngwa. Ya mere, ha malitere inyocha ma nyochaa echiche nke antenna gbara okirikiri iji nweta nnyefe mgbaàmà na arụmọrụ nnata ka mma.

Na 1958, Paul G. Montgomery, onye injinia na Radar Systems Corporation dị na United States, mepụtara antenna mpi nwere njirimara polarization gburugburu, nke a na-akpọ Montgomery Antenna. Nke a bụ mmejuputa mbụ nke antenna opi gburugburu nke nwere polarized ma dọta uche na nnyocha zuru ụwa ọnụ.

N'ime iri afọ ndị sochirinụ, e meela nnyocha ma mepụta antenna opi gbara okirikiri nke nwere polar. Ndị injinia emeela nnwale sara mbara na nyocha echiche n'ịmepụta na imeziwanye nhazi na arụmọrụ nke antenna opi gbara okirikiri nke nwere polar.

N'afọ 1960, e ji eriri mpi okirikiri nke nwere polar gburugburu mee ihe n'ọtụtụ ebe n'ihe gbasara nkwukọrịta. Uru nke eriri mpi okirikiri nke nwere polar gburugburu bụ na ọ nwere ike inweta mkpuchi mgbaàmà ka mma na ikike mgbochi-nnyefe, ọ dịkwa mma karịsịa maka gburugburu mgbasa ozi ọtụtụ ụzọ na sistemụ nkwukọrịta ikuku.

N'afọ 1980 na 1990, site na mmepe nke nkwukọrịta satịlaịtị na teknụzụ radar, agbasawanyela usoro ojiji nke antenna opi gburugburu nke nwere polar. A na-ejikarị antenna opi gburugburu nke nwere polar eme ihe n'ebe nkwukọrịta satịlaịtị, sistemụ radar, na mpaghara agha na ụgbọelu.

Site na ọganihu teknụzụ eletrọnịkị na-aga n'ihu, a ka na-emeziwanye usoro nhazi na mmepụta nke antenna opi gburugburu nwere polar. Antenna opi gburugburu nke oge a na-eji ihe ndị dị elu na usoro mmepụta iji nye oke ugboro ọrụ dị elu, arụmọrụ ka mma na obere nha.

Kedu ka antenna mpi okirikiri si arụ ọrụ

Antenna mpi ndị nwere polar gburugburu na-enweta njirimara radieshon gburugburu site na geometry na imewe pụrụ iche ha. Ụkpụrụ ọrụ nke antenna a dabere na njirimara ndị a dị mkpa:

Ọdịdị mpi: Antenna mpi gbara okirikiri na-ejikarị usoro radiator dị ka mpi. Nhazi nke antenna mpi na-eme ka mgbaàmà ahụ gbasaa n'ime mpi ahụ mgbe niile, si otú a na-emepụta njirimara radieshon kpọmkwem nke nwere ike imezu ihe achọrọ maka polarization gburugburu.

Njikọta: A na-etinyekarị njikọta pụrụ iche n'ime eriri mpi iji jikọta ihe ndị dị n'ọhịa eletriki kwụ ọtọ na nke kwụ ọtọ nke nwere ọdịiche nke ogo 90. Nhazi a na-enye ohere ka eriri ahụ mepụta usoro redio gburugburu nke nwere polarized.

Radiation nke ụdị dị iche iche: Nhazi nke antenna mpi nke nwere polar gburugburu na-enye ya ohere ịgbasa ọtụtụ ụdị nke ubi elektrọnik n'otu oge, gụnyere akara okirikiri nke nwere polar gburugburu nke a na-atụgharị na ntụziaka polarization dị iche iche.

Ugbu a, a na-eji antenna opi gbara okirikiri eme ihe n'ọtụtụ ọnọdụ ngwa dị iche iche, gụnyere nkwukọrịta satịlaịtị, nkwukọrịta ekwentị, nha redio, ikuku, radar, na drones.
