Yagi antenna ndi mathero owombera antenna opangidwa ndi oscillator (nthawi zambiri amakhala opindidwa oscillator), chiwonetsero cha oscillator), ndipo otsogolera angapo operekera omwe adakonzedwa mofananamo. Mu 1920s, hidreesugu wagi ndi Taiki Uta kuchokera ku Tohoku University ku Japan adapanga nsando iyi, yotchedwa "Yagi antenna" kapena "Yagi antenna".

Khalidwe

1. Malangizo amphamvu: Antenna ali ndi mayendedwe abwino ndipo amatha kuyang'ana pawailesi munjira inayake. Malangizo okwanira ma radiation ndi ofanana ndi wotsogolera, akupilira bwino zopinga ndi kusokonezedwa pamayendedwe osagwirizana.
2. Phindu lalikulu: poyerekeza ndi dipole antennas, lipenga antena ali ndi phindu lalikulu ndipo lingakuthandizeni kulandiridwa ndi kuwonekera.
3. Kapangidwe kakang'ono: kokhazikika kwa oscillators, owonerera okhazikika, ndipo otsogolera angapo operekera omwe adapangidwa mofananamo, zinthuzo ndizosavuta kupeza, mtengo wake ndi wochepa, ndipo ndizosavuta kudyetsa.

Karata yanchito

1. Munda wolankhula: rf nyanga intenna imagwiritsidwa ntchito polankhulana komanso kuyankhulana mobwerezabwereza, komanso kugwiritsidwanso ntchito ngati wailesi yanthawi yayitali, ndipo amathanso kugwiritsidwa ntchito ngati paradi ya mafoni am'manja a Extraves kuti apititse mafoni am'manja. Itha kukulitsa zokutira ndikusintha mphamvu yamagetsi m'makonde ma rickoks, oyenera kulumikiza nyumba zakutali kapena kukulitsa zazikulu.
2. Mu gawo laumutauni ndi kanema wawayilesi, ma microwave chimagwiritsidwa ntchito nthawi zambiri ngati kanema wawayilesi, yomwe imatha kulandira mavilewa kanema m'njira zina.
3. Munda wa radar: chifukwa cha mayendedwe ake komanso mawonekedwe ake, mphete ya millimeter tinyanga ta kugwiritsidwa ntchito pakuwona mipata ya radar.
4. Minda ina: Mm Short Antenna alinso ndi ntchito m'makampani, kupeza deta, kuwunika kwasayansi, komanso zida zowunikira, komanso kufalitsa chizindikiro kwina kwasayansi.
Yagi Antenna adagwiritsidwa ntchito kwambiri m'magawo ambiri osalankhula chifukwa cha kapangidwe kake kosavuta, mitengo yotsika mtengo, komanso ntchito yabwino.

ChiyeneroImathandizira Yagi antenas kuphimba pafupipafupi mpaka 173mhz. Timapereka Quon Propec Antennas Chuma 7dbi, komanso lipenga lokhala ndi lilar anterolad malingana ndi makasitomala.
