Tsanangudzo yemagnetic antenna
Ngatitaurei nezve kuumbwa kwemagineti antenna, iyo yakajairwa sucker antenna pamusika inonyanya kuumbwa ne: antenna radiator, yakasimba magineti sucker, feeder, antenna interface yezvi zvidimbu zvina.
1, iyo antenna radiator zvinhu isimbi isina tsvina, mhangura yakachena, memory alloy uye zvimwe zvinhu, chimiro chinowanzo kuve chikwapuro kana tsvimbo.Themagnetic antennaradiator ichokwadi unipolar (chikwapuro) antenna, inova symmetric oscillator ine ruoko rumwe chete perpendicular kune yakanaka conductor ndege (pasi).Zvinoenderana neiyo antenna musimboti, iyo resonant frequency yewaya antenna ndeye yakakosha kuwanda kwe1/2 wavelength, uye zvinoenderana nemusimboti wegirazi, pane yakanaka isingaperi ndege, yakaringana saizi yemagetsi yemagnetic antenna ndeye 1/4 wavelength. , uye kana kuwana kuchizovandudzwa, kurodha kwepakati kunogona kushandiswa kuwedzera urefu hweantenna radiator (1/4 wavelength integral multiple).
2, basa reiyo yakasimba magineti chuck kugadzirisa antenna yese uye kuona kuti chuck antenna iri kusangana nesimbi iri kuyamwa.
3, iyo yekudyisa kazhinji RG yakatevedzana (RG58, RG174), 3D waya uye zvichingodaro.
4, antenna interface yakajairika ndeiyi: N musoro, SMA, BNC, TNC, I-PEX uye mamwe marudzi emhando, pakati peiyo magineti antenna anowanzo shandiswa zvibatanidza N musoro, SMA, BNC, TNC, nezvimwewo, murume nemukadzi, sarudza iyo antenna inofanirwa kutenga chinongedzo chinoenderana nemidziyo.
Nyaya huru dzekushandiswa kwemagineti antenna
Kungokujekesera iwe, sei dhishi rekusveta rinonamatira kusimbi?
Kubva pamatweets edu apfuura, tinogona kuziva kuti mashandiro emagetsi eiyo antenna ane hukama zvakanyanya nenharaunda yaanoshandiswa, uye iyo resonant frequency inobatwa neiyo dielectric yenguva dzose yezvinhu zvakatenderedza antenna, uye kushandiswa kwayo uye kuita kwayo hakugone. kupatsanurwa kubva kumamiriro ekugadzira zvinodiwa uye nzvimbo yekuisa.
Radiator yeantenna yekusveta dish yataurwa pamusoro iyi unipolar antenna.Zvinoenderana neiyo mufananidzo musimboti, unipolar antenna ine kureba h uye mufananidzo wayo inogadzira symmetric oscillator ine kureba 2h, iyo munda wayo wepamusoro hafu nzvimbo wakafanana neiyo symmetric oscillator, uye simba remunda muchikamu chezasi zero
Kazhinji kutaura, iyo magineti antenna inonyanya kushandiswa mukabati, denga remota kana nharaunda yakafanana, saka inogadzirwa pahwaro hweakasiyana kabati uye mota dzemuviri mhando, kuitira kuti saizi yesimbi pasi chikamu cheredhiyo wave. wavelength yefrequency yekukurukurirana inova chikamu cheantenna.Naizvozvo, iyo yakasiyana yekumisikidza chinzvimbo inokanganisa zvakananga shanduko yeyekutanga dhizaini magetsi maparamita eantenna, kunyanya iyo resonant frequency uye neradiation kutungamira.
Iyo radiation yekutungamira dhizaini yeimwe-quarter wavelength unipolar antenna pane inopera dhisiki (mukushandisa kwekushandisa, iyo yakadzika simbi dhisiki inogumira uye haigone kuumba yakazara girazi mufananidzo), uye kune zvakare imwe radiation munzvimbo yepasi yepakati (diffraction athari. ).
Kuita kwemagineti sucker antenna kwakasiyana zvachose kana yakashambadzirwa pamutumbi wesimbi wehukuru hwakasiyana.Naizvozvo, kana uchishandisa sucker antenna, tinokurudzira mapoinzi maviri anotevera:
1, inofanirwa kuve yakashongedzwa pamusoro pekabati kana locomotive kuti ive nechokwadi chehurefu uye nemwaranzi nzira, kuitira kuti utambe kuita kwakanyanya kweantenna;Kana iyo yakaiswa mune zvimwe zvikamu, inokonzeresa shanduko mukumira wave, kutungamira pateni uye kukwidziridza Angle, inokanganisa kutaurirana.
2, nesezvinobvira kuisa antenna munzvimbo yakakura yekuona, kudzivirira kuisirwa mugomba kana yakaoma electromagnetic nharaunda, nenzira iyi chete inogona kuvandudza kunaka kwekutaurirana, kuderedza ruzha rwekumashure uye zvimwe zvisingatarisike zvinokanganisa zviitiko.
Kushandiswa kwemagineti antenna
Kana zvasvika pakushandiswa kwemagineti antenna, ngatitangei kutaura nezve zvakanakira zvayo.Kana yakaiswa nemazvo, antenna yekuyamwa ine yakamira iri nani wave ratio uye nepamusoro-soro pane yakavakirwa-mukati antenna, uye hapana kugadzirisa kunodiwa.Iine glue stick antenna mune imwechete frequency bhendi uye saizi yechimiro, kuwana kwakakwira, kureba kwekufambisa kureba, uye nzvimbo dzakasiyana dzekuisa dzinogona kusarudzwa zvinoenderana nezvinodiwa chaizvo zvekushandisa.
Pamusoro pezvakanakira zviri pamusoro, iyo antenna yekuyamwa inewo akasiyana mashandisiro, mukuwedzera kune yedu yemazuva ese inooneka mashini ekutengesa, kuratidzira makabati, mota redhiyo, inogona zvakare kuiswa kune isina waya module uye isina waya magedhi ane mwero kuwana zvinodiwa.
Magnetic antenna inogona kushandiswa kunze kwemagetsi bhokisi, mota.Kana ichishandiswa kunze, radome inogona kugadzirwa nefiberglass uye zvimwe zvinhu, izvo zvinogona kusapinda mvura uye mhepo.
Magnetic antenna inogona zvakare kushandiswa mumashini ekutengesa, hwaro hweantenna yakasimba magineti sucker, iri nyore kuisa, isiri nyore kudonha.
Magnetic antenna inogona zvakare kushandiswa muwireless mita kuverenga, antenna chimiro chakareruka, chitarisiko chakanaka
