Chii chinonzi Full-Wave Dipole Antenna?
Antena yedipole yakazara-wave iantenna yedipole ine urefu hwese hwemuchina wekufambisa hunenge hwakaenzana nehurefu hwewavelength imwe chete pafrequency yekushanda. Nemamwe mashoko, kana wavelength ichimiririrwa ne λ, hurefu hwese hwedipole hunenge λ.
Kana ichienzaniswa nehafu-wave dipole, full-wave dipole ine kugoverwa kwakaomarara kwemagetsi nemagetsi pamwe chete neconductor. Musiyano uyu unokanganisa zvakananga inopinda mukati, patani yemwaranzi, uye mashandiro ekushandisa.
Kugoverwa Kwezvino uye Kwemagetsi
Nepo paine dipole yakazara yemafungu, kondakita inogona kuonekwa sezvikamu zviviri zvehafu-wavelength zvakabatana pamwe chete. Pamwe chete neantenna, kugoverwa kwemagetsi kunochinja chikamu, zvichireva kuti zvikamu zvakasiyana zvekondakita zvinogona kutakura magetsi munzira dzakasiyana panguva imwe chete.
Nekuda kwehukama hwechikamu ichi, minda yemagetsi inoburitswa nezvikamu zvakasiyana zveantenna inogona kusimbisana mune dzimwe nzira uku ichidzimana zvishoma kune dzimwe nzira. Ichi ndicho chimwe chezvikonzero zvikuru nei maitiro emwaranzi emupopoma wefull-wave akasiyana neaya emupopoma wehafu-wave.
Zviratidzo zveMirairo yeDipole Yakazara-Wave
Dipole yakazara-wave haingoburitse pateni yemwaranzi yakafanana nedipole yehafu-wave. Mudipole yehafu-wave, mwaranzi inowanzova yakasimba zvikuru murutivi rwakafara. Zvisinei, kune dipole yakazara-wave, kudzima kwechikamu kunogona kuderedza mwaranzi mune dzimwe nzira uye kukonzera kuti pateni yemwaranzi ipatsanurwe kuita ma lobes akawanda.
Izvi zvinoreva kuti dipole yakazara-wave inogona kuburitsa simba remagetsi, asi maitiro ayo emwaranzi haawanzo kuve nyore uye haashande zvakanaka kune akawanda mashandisirwo eantenna anoshanda. Pamusoro pezvo, feed point impedance yepole yakazara-wave inodyiswa pakati inogona kunge yakakwira, izvo zvinoita kuti kuwirirana kweimpedance kuve kwakaoma.
Nei Zviporiso Zvizere-Wave Zvisingawanzoshandiswa
Kunyangwe full-wave dipole ichibatsira kunzwisisa kugoverwa kwemagetsi eantenna uye maitiro emwaranzi, haiwanzo shandiswa seantenna inoshanda. Pane zvikonzero zvakati wandei zveizvi.
Chekutanga, maitiro ayo emwaranzi akaomarara kupfuura e dipole yehafu-wave. Pamashandisirwo anoda maitiro emwaranzi anofanotaurwa uye ari nyore, dipole yehafu-wave inowanzo kuve nyore kugadzira nekushandisa.
Chechipiri, kupindirana kweimpedance yedipole yewave-full kunogona kuoma kuenderana netambo dzemagetsi dzinoshandiswa. Kuenzanisa kweimpedance kusina kunaka kunogona kukonzera kuwedzera kuratidzwa, kudzikira kwesimba rekufambisa, uye kudzikira kwekushanda zvakanaka kwesystem.
Chechitatu, mwaranzi inobva kumativi akasiyana eantenna inogona kukanzura zvishoma mune dzimwe nzira. Izvi zvinoita kuti antenna isakodzere kana gwara guru remwaranzi rakasimba uye rakagadzikana richidikanwa.
Kukosha kweUinjiniya
Kubva pamaonero einjiniya, dipole ye "full-wave" inonyanya kukosha se "theoretical model" pane se "antenna" inoshandiswa zvakanyanya. Inobatsira mainjiniya kunzwisisa kuti kureba kwe "antenna", "current phase", "feed position", uye "electromagnetic field distribution" zvinokanganisa sei mashandiro emwaranzi.
MumaRF chaiwo uye ma microwave systems, kusarudzwa kwema antenna kunowanzoenderana nehuwandu hwema frequency anodiwa, gain, polarization, impedance matching, radiation pattern, uye installation conditions. Kune akawanda ma high-frequency measurement uye communication applications, horn antennas, waveguide antennas, uye mamwe ma specialized antenna structures anowanzo shandiswa nekuti anopa kushanda kwakasimba uye kunodzorwa.
Mhedziso
Dipole yakazara-wave iantenna yedipole ine urefu hwese hwe conductor hunosvika wavelength imwe chete. Nekuda kwekuchinja kwechikamu chemagetsi ari pamwe chete ne conductor, maitiro ayo emwaranzi akaomarara kupfuura e half-wave dipole. Kunyangwe ichigona kuburitsa simba remagetsi, pateni yayo yemwaranzi uye hunhu hwe impedance zvinoita kuti isanyanyo shandiswa muma antenna anoshanda.
Kunzwisisa full-wave dipole kuchiri kukosha kune dzidziso ye antenna, nekuti kunoratidza kuti wavelength, current distribution, uye phase relationship zvinopesvedzera sei mwaranzi ye antenna. Ruzivo urwu runobatsira kune mainjiniya eRF, vagadziri ve antenna, uye vagadziri ve microwave system pavanoongorora maumbirwo e antenna epamusoro-soro.
Kuti udzidze zvakawanda nezve antenna, ndapota shanyira:
