TS'ELISO HONA

Yagi Antenna ke antenna e thunngoeng ka pheletso e entsoeng ka oscillator e sebetsang (hangata e le oscillator e mennweng), ponts'o e sa bonahaleng, le batsamaisi ba 'maloa ba sa sebetseng ba hlophisitsoeng ka ho bapisa. Lilemong tsa bo-1920, Hidetsugu Yagi le Taiki Uta ba tsoang Univesithing ea Tohoku Japane ba ile ba qapa lenakana lena, le tsejoang ka "Yagi Uta Antenna" kapa "Yagi Antenna" feela.

Sebopeho

1. Tataiso e matla: Antenna e na le tataiso e ntle 'me e khona ho lebisa maqhubu a seea-le-moea sebakeng se itseng. Litaelo tse phahameng tsa mahlaseli li tšoana le tsa motsamaisi, ka katleho li hatella bohlasoa le ho kena-kenana le litsela tse sa lebelloang.
2. Phaello e phahameng: Ha e bapisoa le li-antenna tsa dipole, li-antenna tsa lenaka li na le phaello e phahameng 'me li ka khona ho tšoara matšoao a hōle hamolemo, ho ntlafatsa boleng ba kamohelo le ho hlaka.
3. Sebopeho se bonolo: se entsoe ka li-oscillator tse sebetsang, li-reflectors tse sa sebetseng, le batsamaisi ba 'maloa ba sa sebetseng ba hlophisitsoeng ka mokhoa o ts'oanang, sebopeho se batla se le bonolo, thepa e fumaneha habonolo, theko e tlaase,' me e bobebe, e tiile ebile e bonolo ho fepa.

Kopo

1. Sebaka sa puisano: RF horn antenna e sebelisetsoang puisano ea shortwave le ultra shortwave, joalo ka puisano ea seea-le-moea sa sebaka se selelele, 'me e ka boela ea sebelisoa e le li-antenna tsa ka ntle bakeng sa li-amplifiers tsa mohala oa selefouno ho matlafatsa matshwao a fono. E ka holisa sebaka sa tšireletso le ho ntlafatsa matla a mats'oao ho marang-rang a Wi-Fi, a loketseng ho hokahanya meaho e hole kapa ho atolosa tšireletso e kholo.
2. Lefapheng la khaso le thelevishene, antenna ea lenaka la microwave e atisa ho sebelisoa e le thelevishene e amohelang antenna, e ka amohelang lipontšo tsa thelevishene ka litsela tse itseng le ho ntlafatsa phello ea kamohelo.
3. Tšimo ea radar: Ka lebaka la litšoaneleho tsa eona tsa tataiso le ho fumana, antenna ea lenaka la millimeter wave e ka sebelisoa bakeng sa ho lemoha lipakane ho litsamaiso tsa radar.
4. Likarolo tse ling: Mm wave horn antenna e boetse e na le lits'ebetso indastering, lits'ebetso tsa ho fumana le ho shebella data (SCADA), le merero ea saense le ea bongaka, joalo ka puisano e se nang mohala pakeng tsa lisebelisoa tse hole tsa ho fumana data le lisebelisoa tsa ho beha leihlo, hammoho le ho amohela le ho fetisoa ha matšoao litekong tse ling tsa mahlale.
Yagi antenna e sebelisitsoe haholo mafapheng a mangata a puisano a se nang mohala ka lebaka la sebopeho sa eona se bonolo, litšenyehelo tse tlase tsa tlhahiso, le ts'ebetso e ntle.

QualwaveLisebelisoa tsa Yagi Antennas li koahela lebelo la maqhubu ho fihla ho 173MHz. Re fana ka li-antenna tsa horn tse tloaelehileng tsa phaello ea 7dBi, hammoho le li-antenna tse ikhethileng tse peli ho latela litlhoko tsa bareki.
