Nkọwa nke antenna magnetik
Ka anyị kwuo maka ihe mejupụtara antenna magnetik, antenna sucker nke dị n'ahịa bụ nke kachasị: radiator antenna, sucker magnetik siri ike, onye na-azụ anụ, interface antenna nke akụkụ anọ ndị a.
1, ihe radiator nke antenna bụ igwe anaghị agba nchara, ọla kọpa dị ọcha, alloy ebe nchekwa na ihe ndị ọzọ, ọdịdị ya na-abụkarị ụtarị ma ọ bụ mkpanaka.Nkeantenna magnetikradiator bụ n'ezie antenna unipolar (ụrịa), nke bụ oscillator symmetric nke nwere otu ogwe aka kwụ n'akụkụ ụgbọ elu kacha mma (ala).Dị ka ụkpụrụ antenna si dị, ugboro ole resonant nke eriri waya bụ ihe dị mkpa nke 1/2 wavelength, na dị ka ụkpụrụ mirror si dị, na ụgbọ elu na-enweghị ngwụcha, ezigbo ọkụ eletrik kachasị mma nke antenna magnetik bụ 1/4 wavelength. , ma ọ bụrụ na a ga-emeziwanye uru ahụ, enwere ike iji ntinye etiti mee ka ogologo nke radiator antenna (1/4 wavelength integral multiple).
2, ọrụ nke magnetik siri ike bụ idozi antenna dum wee hụ na antenna chuck na kọntaktị na ígwè a na-aṅụ.
3, onye na-enye nri bụ usoro RG (RG58, RG174), waya 3D na ndị ọzọ.
4, antenna interface a na-ahụkarị bụ: N isi, SMA, BNC, TNC, I-PEX na ụdị interface ndị ọzọ, n'etiti antenna magnetik a na-ejikarị njikọ bụ isi N, SMA, BNC, TNC, wdg, nwoke na nwanyị, họrọ nke ahụ. antenna ga-azụrịrị njikọ nke dabara na akụrụngwa.
Isi ihe gbasara iji antenna magnetik
Naanị iji dokwuo gị anya, kedu ihe kpatara efere mmiri ara ara ji ejigide ígwè?
Site na tweet anyị gara aga, anyị nwere ike ịmara na arụmọrụ eletriki nke antenna nwere njikọ chiri anya na gburugburu ebe a na-eji ya eme ihe, na ugboro ole resonant na-emetụta dielectric mgbe niile nke ihe dị n'akụkụ antenna ahụ, na iji ya na arụmọrụ ya enweghị ike. kewapụ ya na ihe ndị chọrọ imewe na gburugburu ebe nrụnye.
Igwe ọkụ nke antenna efere mmiri ahụ a kpọtụrụ aha n'elu bụ antenna unipolar.Dị ka ihe oyiyi ụkpụrụ, a unipolar antenna na ogologo h na oyiyi ya na-etolite a symmetric oscillator na ogologo 2h, onye ubi na elu ọkara ohere bụ otu ihe ahụ nke symmetric oscillator, na ubi ike na ala ọkara ohere bụ. efu
N'ikwu okwu n'ozuzu, a na-ejikarị antenna magnetik mee ihe na kabinet, ụlọ nke ụgbọ ala ma ọ bụ gburugburu ebe obibi yiri ya, n'ihi ya, e mere ya na ndabere nke dị iche iche kabinet na ụgbọ ala ahụ ụdị, nke mere na size nke metal ala akụkụ nke redio ife. Ogologo ogologo oge nzikọrịta ozi na-aghọ akụkụ nke antenna.Ya mere, ọnọdụ nrụnye dị iche iche ga-emetụta ngbanwe nke ihe nrụpụta eletrik mbụ nke antenna, karịsịa ugboro ugboro na ntụgharị radieshon.
Eserese ntụzịaka radieshon nke otu ụzọ n'ụzọ anọ wavelength unipolar antenna na diski nwere njedebe (n'iji ya eme ihe, diski diski a gbanyere mkpọrọgwụ nwere oke na enweghị ike imepụta onyonyo enyo zuru oke), yana nwekwara ụfọdụ radieshon na obere oghere ọkara (mmetụta dị iche iche). ).
Arụmọrụ nke eriri magnetik sucker dị iche kpamkpam mgbe a na-etinye ya na ahụ igwe dị iche iche.Ya mere, mgbe ị na-eji antenna sucker, anyị na-akwado isi ihe abụọ ndị a:
1, a na-achọ ka a na-etinye ya n'elu ụlọ elu ma ọ bụ locomotive iji hụ na ịdị elu na ntụziaka radieshon, iji rụọ ọrụ kacha mma nke antenna;Ọ bụrụ na etinyere ya na akụkụ ndị ọzọ, ọ ga-eme ka mgbanwe dị na ebili mmiri guzoro ọtọ, ụkpụrụ nduzi na elu elu, na-emetụta oke nkwurịta okwu.
2, dị ka o kwere mee iji wụnye antenna na mbara ihu dị iche iche, zere ntinye n'ime oghere ma ọ bụ gburugburu ebe obibi electromagnetic, naanị n'ụzọ dị otú a nwere ike imeziwanye ogo nkwurịta okwu, belata ụda azụ na ihe ndị ọzọ na-enweghị atụ nnyonye anya.
Ngwa nke antenna magnetik
Mgbe a bịara n'iji antenna magnetik eme ihe, ka anyị buru ụzọ kwuo banyere uru ya.Ọ bụrụ na arụnyere ya nke ọma, antenna mmiri ahụ nwere oke ebili mmiri kwụ ọtọ na arụmọrụ dị elu karịa antenna arụnyere, ọ nweghị nhazi ọ bụla achọrọ.Site na antenna stick stick na otu ugboro band na nhazi nha, uru ahụ dị elu, ebe nnyefe dị ogologo, enwere ike ịhọrọ ọnọdụ nrụnye dị iche iche dịka mkpa eji eme ihe.
Na mgbakwunye na uru ndị a dị n'elu, antenna suction nwekwara ọtụtụ ihe eji eme ihe, na mgbakwunye na igwe na-ere ahịa anyị na-ahụ kwa ụbọchị, igbe awara awara, redio ụgbọ ala, nwekwara ike itinye ya na modul ikuku na ọnụ ụzọ ikuku na-achọ oke uru.
Enwere ike iji antenna magnetik na igbe eletrik n'èzí, ụgbọ ala.Mgbe a na-eji ya eme ihe n'èzí, radome nwere ike iji fiberglass na ihe ndị ọzọ mee ihe, nke nwere ike ịbụ mmiri na-adịghị na ikuku.
A pụkwara iji antenna magnetik mee ihe na igwe na-ere ahịa, isi nke antenna bụ ihe siri ike magnetik, dị mfe ịwụnye, ọ dịghị mfe ịda.
Enwere ike iji antenna magnetik na-agụ mita ikuku, nhazi antenna dị ọkụ, ọdịdị mara mma
