Banyere antenna, ebe a ka ị gwa gị ~

Antenna, nke enwere ike iji nyefee akara na ịnata akara, na-emegharịghachi, nwere nkwụghachi azụ, a pụkwara iwere ya dị ka transducer, nke bụ ngwaọrụ interface n'etiti sekit na oghere.Mgbe ejiri ya na-ebufe mgbaama, mgbama ọkụ eletrik dị elu nke sitere na isi mmalite mgbaàmà na-agbanwe ka ọ bụrụ ebili mmiri electromagnetic na oghere ma na-ebupụ n'akụkụ ụfọdụ.Mgbe ejiri ya nweta akara, ebili mmiri electromagnetic na oghere na-atụgharị ka ọ bụrụ akara eletrik ma bufee onye nnata site na eriri.

Nhazi nke antenna

Enwere ike kewaa antennas dịka ụzọ dị iche iche si dị:

Nhazi site na iji: enwere ike kewaa n'ime antenna nkwukọrịta, antenna telivishọn, antenna radar na ndị ọzọ

Dabere na nhazi nke bandwit na-arụ ọrụ: enwere ike kewaa n'ime antenna mkpirisi, antenna dị mkpụmkpụ, antenna microwave na ndị ọzọ.

Dabere na nhazi nke Directivity: enwere ike kewaa n'ime antenna omnidirectional, antenna directional, wdg

Dị ka nhazi ọkwa: enwere ike kewaa n'ime antenna linear, antenna planar na ndị ọzọ

Antenna ntụzịaka: Ntụziaka antenna nwere oke na ntụzịaka kwụ ọtọ na-erughị ogo 360.

Enwere ike iji antennas omnidirectional na-anata/ebufe akara n'akụkụ niile n'otu oge.Nke a nwere ike bụrụ ihe na-achọsi ike ma ọ bụrụ na achọrọ ịnata/bufee ozi n'akụkụ niile, dịka ya na ụfọdụ ụlọ ọrụ redio ọdịnala.Otú ọ dị, a na-enwekarị ọnọdụ ebe a na-amata ntụziaka nke mgbaàmà ma ọ bụ dị oke.Dịka ọmụmaatụ, site na teliskop redio, a maara na a ga-anata akara n'ụzọ enyere (site na mbara igwe), ebe antennas omni-directional adịghị arụ ọrụ nke ọma n'ịweta akara ndị na-adịghị ike site na kpakpando.N'okwu a, enwere ike iji antenna ntụzi aka nwere uru antenna dị elu iji nweta ike mgbama na ntụziaka enyere.
