Leqhubu la Yagi Antennas RF Microwave Millimeter Wave mm
Antenna ea Yagi ke antenna e besitsoeng qetellong e entsoeng ka oscillator e sebetsang (hangata e le oscillator e menahaneng), reflector e sa sebetseng, le batsamaisi ba 'maloa ba sa sebetseng ba hlophisitsoeng ka nako e le' ngoe. Lilemong tsa bo-1920, Hidetsugu Yagi le Taiki Uta ba tsoang Univesithing ea Tohoku Japane ba ile ba qapa antenna ena, e tsejoang e le "Antenna ea Yagi Uta" kapa feela "Antenna ea Yagi".
Tšobotsi
1. Tsela e matla ea ho sheba: Antenna e na le tsela e ntle ea ho sheba 'me e ka tsepamisa maqhubu a seea-le-moea ka lehlakoreng le itseng. Tsela e phahameng ka ho fetisisa ea ho sheba mahlaseli e tšoana le ea motsamaisi, e thibela ka katleho ho se tsitse le ho sitisoa ke litsela tse seng tsa sepheo.
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 hapa matšoao a hole hamolemo, li ntlafatsa boleng ba kamohelo le ho hlaka.
3. Sebopeho se bonolo: se entsoe ka di-oscillator tse sebetsang, di-reflector tse sa sebetseng, le batsamaisi ba mmalwa ba sa sebetseng ba hlophisitsoeng ka nako e le nngwe, sebopeho se bonolo, thepa e fumaneha habonolo, theko e tlase, mme e bobebe, e tiile, mme e bonolo ho e fepa.

1. Sebaka sa puisano: Antena ea lenaka la RF e sebelisetsoang puisano ea maqhubu a makhutšoanyane le maqhubu a makhutšoanyane a mangata, joalo ka puisano ea seea-le-moea sa hole, 'me e ka boela ea sebelisoa e le li-antenna tsa kantle bakeng sa li-amplifier tsa matšoao a mohala oa thekeng ho ntlafatsa matšoao a mohala oa thekeng. E ka atolosa sebaka sa ho koahela le ho ntlafatsa matla a matšoao marangrang a Wi Fi, e loketse ho hokela mehaho e hole kapa ho atolosa ho koahela ho hoholo.
2. Lefapheng la kgaso le thelevishene, antenna ya lenaka la microwave hangata e sebediswa e le antenna e amohelang thelevishene, e ka amohelang matshwao a thelevishene ka ditsela tse itseng le ho ntlafatsa phello ya kamohelo.
3. Tšimo ea radar: Ka lebaka la litšobotsi tsa eona tsa ho sheba le ho fumana leseli, antenna ea lenaka la maqhubu a millimeter e ka sebelisoa ho lemoha lipheo lits'ebetsong tsa radar.
4. Masimo a mang: Antenna ea lenaka la Mm wave le eona e na le lits'ebetso indastering, litsamaisong tsa ho fumana le ho beha leihlo data (SCADA), le mererong ea saense le ea bongaka, joalo ka puisano e se nang mohala pakeng tsa ho fumana data hole le lisebelisoa tsa ho beha leihlo, hammoho le kamohelo le phetisetso ea matšoao litekong tse ling tsa saense.
Antenna ea Yagi e sebelisitsoe haholo masimong 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 maqhubu a fihlang ho 173MHz. Re fana ka li-antenna tse tloaelehileng tsa gain horn tsa gain 7dBi, hammoho le li-antenna tse entsoeng ka mokhoa o ikhethileng oa dual polarized horn ho latela litlhoko tsa bareki.
