Munhepfenyuro yeredhiyo, unogona kuona izvozvo
FM dipole antenna inogamuchirwa muzvidimbu zvakawanda zvemidziyo. Inogona kushandiswa yega kana kusanganiswa nemamwe ma FM antennas kugadzira antenna array. Zvinogona kutaurwa kuti iyo FM dipole antenna ndeimwe yemhando dzakanyanya kukosha dzeFM antenna. Naizvozvo, zvakakosha kwazvo kuve nekunzwisisa kwekutanga kweFM dipole antenna. Ichi chinyorwa chichaita sumo yekutanga yeFM dipole antenna kubva pakuunzwa kweFM radio dipole antenna, iyo inoshanda yeFM radio dipole antenna, rudzi rwe dipole antenna, uye maitiro ekusarudza akanakisa FM dipole antenna.
Chokwadi chinonakidza cheFM Dipole Antenna
Mumunda weredhiyo uye nharembozha, iyo FM radio dipole antenna ndiyo inonyanya kushandiswa uye yakapusa mhando yeFM antenna. Mazhinji acho anotaridzika sezwi rekuti "T", iro rinoumbwa nemakondukita maviri ane hurefu hwakaenzana uye akabatana magumo-kumagumo. Uye iwo akabatanidzwa netambo pakati pe dipole antenna. FM dipole antenna inogona kushandiswa yega kana kuumba yakanyanya kuoma antenna array (seYagi antenna).
FM radio dipole antenna inogona kushanda muHF, VHF, uye UHF ye frequency band. Kazhinji kutaura, ivo vanozosanganiswa nemimwe michina yemagetsi kugadzira chikamu chakazara. Semuyenzaniso, iyo FM radio dipole antenna ichave yakabatana neFM nhepfenyuro yekutepfenyura kuti igadzire yakakwana RF yekutepfenyura michina; Panguva imwecheteyo, seanogamuchira, inogona kubatana nevanogamuchira seredhiyo kuti igadzire yakakwana RF yekugamuchira michina.
FM Dipole Antenna inoshanda sei?
Isu tinotoziva kuti zita rekuti "dipole" rinoreva kuti antenna ine mapango maviri, kana ine maviri conductor. FM radio dipole antenna inogona kushandiswa seyekufambisa antenna kana kugamuchira antenna. Vanoshanda seizvi:
- Kune yekufambisa dipole antenna, kana iyo FM dipole antenna ikagamuchira chiratidzo chemagetsi, ikozvino inoyerera mune maviri conductor eFM dipole antenna, uye yazvino uye voltage inoburitsa mafungu emagetsi, kureva, masaini eredhiyo uye anopenya kunze.
- Kune iyo inogashira dipole antenna, kana iyo FM dipole antenna ikagamuchira aya masaini eredhiyo, iyo electromagnetic wave muFM dipole antenna conductor inoburitsa masaini emagetsi, oaendesa kumidziyo inogashira uye oashandura kuita ruzha.
Vanoshanda nenzira dzakasiyana, misimboti yavo yakangofanana, asi nzira yekushandura chiratidzo inodzoserwa kumashure.
4 Mhando dzeFM Dipole Antenna
FM dipole antennas inogona kupatsanurwa kuita 4 mhando, iwo ane akasiyana maitiro.
Half-wave dipole antenna
Iyo hafu-wave dipole antenna ndiyo inonyanya kushandiswa. Inoumbwa nemakondukita maviri ane kureba kwechikamu chimwe chete chewavelength yakabatana kumagumo kusvika kumagumo. Hurefu hweantenna ipfupi zvishoma pane yemagetsi hafu yewavelength munzvimbo yemahara. Half-wave dipoles inowanzodyiwa pakati. Izvi zvinopa iri nyore kubata yakaderera impedance feed point.
Multi hafu-wave dipole antenna
Zvinogoneka zvakare kana iwe uchida kushandisa akawanda (kazhinji anopfuura matatu, uye isinganzwisisike nhamba) hafu-wave dipole antennas. Iyi antenna array inonzi Multi hafu-wave dipole antenna. Kunyangwe iyo mwaranzi maitiro akasiyana neayo ehafu-wave dipole antenna, ichiri kushanda nemazvo. Saizvozvo, iyi mhando yeantenna inowanzo dyirwa pakati, iyo inopa zvakare yakaderera feed impedance.
Yakapetwa dipole antenna
Sezvinoratidzwa nezita, iyi fomu yeFM dipole antenna yakapetwa kumashure. Ichiri kuchengetedza kureba pakati pemigumo miviri yehafu-wavelength, inoshandisa mamwe maconductor kubatanidza migumo miviri pamwechete. Iyo yakapetwa dipole antenna inogona kupa yakakwira yekudyisa impedance uye yakafara bandwidth.
Short dipole antenna
Iyo pfupi dipole antenna antenna iyo kureba kwayo kupfupika kupfuura iyo yehafu-wave, uye kureba kweantenna kunodiwa kuve isingasviki 1/10 yewavelength. Iyo pfupi dipole antenna ine mabhenefiti epfupi antenna kureba uye yakakwirira feed impedance. Asi panguva imwecheteyo, nekuda kwekupikisa kwayo kwakanyanya, kushanda kwayo kwakadzikira zvakanyanya pane kweakajairika dipole antenna, uye mazhinji esimba rayo rinoparara nenzira yekupisa.
Zvinoenderana neakasiyana nhepfenyuro yeredhiyo zvinodiwa, akasiyana FM dipole antennas anosarudzika kusangana nezvinodiwa zvakasiyana zvekutepfenyura.
Maitiro ekusarudza Yakanakisa FM Dipole Antenna?
Iwe unofanirwa kufunga nezve izvi zvinhu pakusarudza iyo FM dipole antenna yekuvaka yako wega nhepfenyuro.
The Working Frequency
Kushanda frequency yeFM dipole antenna yaunoshandisa inofanirwa kuenderana neanoshanda frequency yeFM nhepfenyuro transmitter, zvikasadaro, iyo FM dipole antenna haigone kufambisa nhepfenyuro kazhinji, izvo zvinokonzeresa kukuvadza kumudziyo wekutepfenyura.
Simba rinokwana rakakwana
Imwe neimwe yeFM radio nhepfenyuro ine yakanyanya kutakura kutakura simba rekufambisa. Kana iyo FM dipole antenna isingakwanise kutakura simba rekuparadzira, iyo FM antenna haigone kushanda zvakajairwa.
Yakaderera VSWR
VSWR inoratidza kushanda kweiyo antenna. Kazhinji, VSWR pazasi 1.5 inogamuchirwa. Iyo yakanyanyisa kumira wave ratio inokuvadza transmitter uye kuwedzera mutengo wekugadzirisa.
Kutungamira
FM radio antennas yakakamurwa kuita marudzi maviri: omnidirectional uye inotungamira. Iyo inosarudza kutungamira kweiyo yakanyanya kunyura mwaranzi. FM radio dipole antenna ndeyeomnidirectional antenna. Kana iwe uchida inotungamira antenna, unofanirwa kuwedzera reflector.
Izvi ndizvo zvinhu zvikuru zvinofanirwa kutariswa pakusarudza iyo FM dipole antenna. Kana iwe usati wanzwisisa, ndapota tiudze zvaunoda, uye isu tichagadzirisa mhinduro yehunyanzvi kwauri. Ndapota inzwa wakasununguka kutibata nesu!
FAQ
Maitiro ekuverenga kureba kweiyo FM dipole antenna?
Mamwe dipole antennas anogona kugadzirisa frequency yekushanda ye dipole antenna nekugadzirisa kureba kwe conductor. Iyo conductor kureba inogona kuverengerwa uchishandisa iyi formula: L = 468 / F. L ndiyo kureba kweantenna, mutsoka. F ndiyo frequency inodiwa, muMHz.
Chii chandinofanira kutarisisa kana ndichiisa FM dipole antenna?
Teerera kune matatu mapoinzi paunenge uchiisa FM dipole antenna:
1. Isa dipole antenna yako yakakwirira sezvinobvira pasina zvipingamupinyi;
2. Usarega antenna yako ichibata chero chinhu;
3. Gadzirisa antenna yako uye uidzivirire kubva kumvura nemheni.
Ndeapi marudzi akasiyana eFM dipole antennas?
Kune mana makuru emhando dzeFM dipole antennas:
- Half-wave dipole antenna

Ndeupi rudzi rwekudyisa yakanakira dipole antenna? Ndeipi nzira yekudyisa yakanakira dipole antenna?
Iyo dipole antenna ndeye yakaenzana antenna, saka iwe unofanirwa kushandisa yakaringana feeder, chiri chokwadi mudzidziso. Nekudaro, yekudyisa yakaringana haiwanzo kushandiswa nekuti inonetsa kushanda muzvivakwa uye inongoshanda kubhendi reHF. Mamwe coaxial cables ane balun anoshandiswa.
mhedziso
Chero ani zvake anogona kutenga FM radio dipole antenna uye kumisikidza yavo nhepfenyuro. Chavanongoda zvimwe midziyo yakakodzera uye marezinesi akakodzera. Kana iwe uinewo pfungwa yekutanga nhepfenyuro yako, ungangoda mutengesi akavimbika seFMUSER, nyanzvi yekutepfenyura nhepfenyuro. Tinogona kukupa zvemhando yepamusoro uye zvakachipa redhiyo nhepfenyuro yemidziyo mapakeji uye mhinduro, uye kukubatsira kupedzisa kuvaka uye kuisirwa kwemidziyo kusvika michina yese yava kushanda zvakajairika. Kana iwe uchida kutenga FM dipole antenna uye kuseta yako wega nhepfenyuro, ndapota inzwa wakasununguka kutibata. Tese tiri nzeve!
