Eriri log-periodic bụ eriri ogologo ogologo nke ụkpụrụ ọrụ ya dabere na resonance na nhazi oge. Edemede a ga-ewebatakwa gị antenna log-periodic site na akụkụ atọ: akụkọ ihe mere eme, ụkpụrụ ọrụ na uru nke antenna log-periodic.

Akụkọ ihe mere eme nke log-periodic antennas

Antenna log-periodic bụ eriri obosara obosara nke atụmatụ ya dabere na nhazi oge-oge. Akụkọ ihe mere eme nke antenna log-periodic sitere na 1950s.

Ndị injinia America bụ Dwight Isbell na Raymond DuHamel mere nke mbụ antenna log-periodic na 1957. Mgbe ha na-eme nyocha na Bell Labs, ha haziri antenna brọdband nwere ike ikpuchi ọtụtụ eriri ugboro. Ọdịdị antenna a na-eji geometry log-periodic, nke na-enye ya njirimara radieshon yiri ya n'ogologo oge niile.

N'ime iri afọ ndị sochirinụ, e jirila ma mụọ antennas oge niile. A na-eji ha na mpaghara dịka nkwukọrịta ikuku, igwe onyonyo na redio, sistemụ radar, nha redio, na nyocha sayensị. Njirimara obosara nke eriri log-periodic na-enyere ha aka ikpuchi ọtụtụ eriri ugboro, na-ebelata mkpa mgbanwe ugboro ugboro na ngbanwe antenna, na imeziwanye mgbanwe na ịrụ ọrụ nke sistemu.

Ụkpụrụ ọrụ nke antenna log-periodic dabere na nhazi ya pụrụ iche. Ọ nwere usoro efere igwe na-agbanwe agbanwe, nke ọ bụla na-abawanye ogologo na oghere dịka oge logarithmic si dị. Ihe owuwu a na-eme ka antenna wepụta ọdịiche nke usoro n'ụdị dị iche iche, si otú a na-enweta radieshon obosara.

Ka teknụzụ na-aga n'ihu, nhazi na ụzọ nrụpụta nke antenna log-periodic abawanyela. Antenna log-oge nke oge a na-eji ihe dị elu yana usoro nrụpụta iji kwalite arụmọrụ na ntụkwasị obi antenna.

Enwere ike ịkọwa ụkpụrụ ọrụ ya nkenke dị ka ndị a

1. Ụkpụrụ resonance: Nhazi nke antenna log-periodic dabere na ụkpụrụ resonance. N'otu oge a kapịrị ọnụ, nhazi nke antenna ga-etolite akaghị aka, na-enye ohere ka antenna nata nke ọma ma na-amụba ebili mmiri electromagnetic. Site n'ichepụta ogologo na oghere nke mpempe akwụkwọ ígwè ahụ, antennas log-periodic nwere ike ịrụ ọrụ n'ọtụtụ ọnụọgụ resonant.

2. Ọdịiche nke usoro: Oke log-periodic nke ogologo mpempe ígwè na oghere nke antenna log-periodic na-eme ka mpempe ígwè ọ bụla mepụta ọdịiche nke oge na ugboro dị iche iche. Ọdịiche nke oge a na-eduga n'omume resonant nke antenna n'ọtụtụ dị iche iche, si otú a na-eme ka arụ ọrụ obosara.

3. Nyocha nke beam: Ọdịdị nke antenna log-periodic na-eme ka ọ nwee àgwà radieshon dị iche iche na ugboro dị iche iche. Ka ugboro na-agbanwe, ntụzịaka radieshon na obosara nke antenna na-agbanwekwa. Nke a pụtara na antennas log-periodic nwere ike nyochaa ma mezie doo anya n'okirikiri ogologo oge.

Uru nke antenna log-periodic

1. Njirimara brọdband: Antenna Log-periodic bụ eriri obosara nke nwere ike ikpuchi ọtụtụ eriri ugboro. Ihe owuwu ya na-oge oge na-eme ka antenna nwee njirimara radieshon yiri nke ahụ n'ofe oge niile, na-ewepụ mkpa mgbanwe ugboro ugboro ma ọ bụ ngbanwe antenna, na-eme ka mgbanwe usoro na ịrụ ọrụ dị mma.

2. Uru dị elu na arụmọrụ radieshon: antennas log-periodic na-enwekarị uru dị elu na arụmọrụ radieshon. Ọdịdị ya na-enye ohere resonance n'ọtụtụ ugboro ugboro, na-enye ike radieshon na ike nnabata.

3. Njikwa ntụziaka: Antenna log-periodic na-abụkarị ntụziaka, ya bụ, ha nwere ike radieshon siri ike ma ọ bụ ikike nnabata n'akụkụ ụfọdụ. Nke a na-eme ka antennas log-oge dabara adaba maka ngwa chọrọ ntuziaka radieshon akọwapụtara, dị ka nkwukọrịta, radar, wdg.

4. Mee ka nhazi usoro dị mfe: Ebe ọ bụ na antenna log-periodic nwere ike ikpuchi ọtụtụ ugboro ugboro, enwere ike ime ka nhazi usoro dị mfe na ọnụ ọgụgụ nke antennas nwere ike ibelata. Nke a na-enyere aka belata ọnụ ahịa usoro, belata mgbagwoju anya ma melite ntụkwasị obi.

5. Ọrụ mgbochi nnyonye anya: Antenna Log-periodic nwere ezigbo ọrụ mgbochi nnyonye anya na bandwit ogologo. Ọdịdị ya na-enyere antenna ahụ aka ka ọ dị mma nzacha akara ngosi ugboro na-achọghị ma melite nguzogide sistemụ na nnyonye anya.

Na nkenke, site n'ichepụta ogologo na oghere nke mpempe akwụkwọ ígwè nke ọma, antenna log-periodic nwere ike ịrụ ọrụ n'ọtụtụ ọnụọgụ resonant, nwere njirimara obosara, uru dị elu na arụmọrụ radieshon, njikwa nduzi, nhazi usoro dị mfe na mgbochi nnyonye anya. . uru arụmọrụ. Nke a na-eme antennas logarithmic nke oge a na-ejikarị na nkwukọrịta ikuku, radar, nyocha sayensị na mpaghara ndị ọzọ.
