Yagi Antenna ndi mlongoti wothamangitsidwa kumapeto womwe umapangidwa ndi oscillator yogwira (kawirikawiri oscillator yopindika), chowunikira, ndi owongolera angapo omwe amapangidwa molumikizana. M’zaka za m’ma 1920, Hidetsugu Yagi ndi Taiki Uta ochokera ku yunivesite ya Tohoku ku Japan anatulukira mlongoti umenewu, womwe umadziwika kuti “Yagi Uta Antenna” kapena kungoti “Yagi Antenna”.

Khalidwe

1. Mayendedwe amphamvu: Mlongoti uli ndi mayendedwe abwino ndipo umatha kuyang'ana mafunde a wailesi mbali ina yake. Kumayambiriro kwa ma radiation ndikofanana ndi kwa wotsogolera, kutsekereza kusokoneza komanso kusokoneza komwe sikunapezeke.
2. Kupindula kwakukulu: Poyerekeza ndi tinyanga ta dipole, mlongoti wa nyanga umakhala ndi phindu lalikulu ndipo umatha kujambula bwino zizindikiro zakutali, kupititsa patsogolo kulandiridwa ndi kumveka bwino.
3. Mapangidwe osavuta: opangidwa ndi oscillator yogwira ntchito, zowonetsera zopanda pake, ndi otsogolera angapo osasunthika omwe amakonzedwa mofanana, mapangidwe ake ndi ophweka, zipangizo ndi zosavuta kuzipeza, mtengo wake ndi wotsika, ndi wopepuka, wolimba, komanso wosavuta kudyetsa.

Kugwiritsa ntchito

1. Malo olumikizirana: Mlongoti wa nyanga wa RF womwe umagwiritsidwa ntchito polumikizana ndi ma shortwave ndi ma ultra shortwave, monga kulumikizana ndi wailesi yakutali, komanso angagwiritsidwe ntchito ngati tinyanga zakunja za amplifiers a foni yam'manja kuti akweze ma sign a foni yam'manja. Itha kukulitsa kufalikira ndikuwongolera mphamvu zama siginecha mumanetiweki a Wi Fi, oyenera kulumikiza nyumba zakutali kapena kukulitsa kufalikira kwakukulu.
2. Pankhani yowulutsa ndi wailesi yakanema, mlongoti wa nyanga ya microwave nthawi zambiri umagwiritsidwa ntchito ngati wailesi yakanema yolandila, yomwe imatha kulandira ma siginecha apawailesi yakanema molunjika ndikuwongolera momwe amalandirira.
3. Munda wa radar: Chifukwa cha mayendedwe ake ndi kupindula kwake, mlongoti wa nyanga ya millimeter wave ungagwiritsidwe ntchito pozindikira zomwe zili mu makina a radar.
4. Minda ina: Mm wave horn antenna imakhalanso ndi ntchito m'makampani, machitidwe opezera deta ndi kuyang'anira (SCADA), ndi zolinga za sayansi ndi zamankhwala, monga kulankhulana opanda zingwe pakati pa kupeza deta yakutali ndi zipangizo zowunikira, komanso kulandira chizindikiro ndi kutumiza muzoyesera zina za sayansi.
Yagi antenna yakhala ikugwiritsidwa ntchito kwambiri m'magawo ambiri olankhulirana opanda zingwe chifukwa cha mawonekedwe ake osavuta, mtengo wotsika wopanga, komanso magwiridwe antchito abwino.

Qualwaveamapereka Yagi Antennas kuphimba pafupipafupi osiyanasiyana mpaka 173MHz. Timapereka tinyanga ta nyanga za phindu la 7dBi, komanso tinyanga tambiri tomwe timapanga polarized nyanga malinga ndi zomwe makasitomala amafuna.
