BATA IZVOZVI

Yagi Antenna iantenna inobatidzwa nemagetsi inoumbwa ne active oscillator (kazhinji kacho inopetwa), passive reflector, uye madhairekitori akati wandei akarongwa panguva imwe chete. Muma1920, Hidetsugu Yagi naTaiki Uta vekuTohoku University muJapan vakagadzira iyi antenna, inozivikanwa se "Yagi Uta Antenna" kana kungoti "Yagi Antenna".

Hunhu

1. Kutungamira kwakasimba: Antena ine kutungamira kwakanaka uye inogona kutarisisa mafungu eredhiyo munzira chaiyo. Kutungamira kwakanyanya kwemwaranzi kwakafanana nekwemutungamiriri, zvichidzivirira kuzara kwezvinhu uye kupindira munzira dzisiri dzechinangwa.
2. Kuwana kwakanyanya: Kana tichienzanisa nemaantenna e dipole, antenna yenyanga ine kuwedzera kwakanyanya uye inogona kubata zviri nani masaini ari kure, zvichivandudza kunaka kwekugamuchira uye kujeka.
3. Maumbirwo akareruka: akagadzirwa nema oscillator anoshanda, ma passive reflectors, uye ma passive directors akati wandei akarongwa panguva imwe chete, maumbirwo acho akareruka, zvinhu zviri nyore kuwana, mutengo wakaderera, uye akareruka, akasimba, uye ari nyore kupa chikafu.

Kushandiswa

1. Nzvimbo yekutaurirana: Antena yeRF horn inoshandiswa pakutaurirana kweshortwave ne ultra shortwave, senge kutaurirana kweredhiyo kure, uye inogona kushandiswawo se antenna dzekunze dzema amplifiers efoni nharembozha kuti iwedzere masaini efoni nharembozha. Inogona kuwedzera huwandu hwemasaini uye kuvandudza simba remasaini muWi Fi network, yakakodzera kubatanidza zvivakwa zviri kure kana kuwedzera kufukidzwa kukuru.
2. Mubasa rekuparadzira neterevhizheni, antenna ye microwave horn inowanzo shandiswa se antenna inogamuchira terevhizheni, iyo inogona kugamuchira masaini eterevhizheni munzira dzakatarwa uye kuvandudza mhedzisiro yekugamuchira.
3. Munda weRadar: Nekuda kwekwaunoenda uye kugona kwawo kuwana ruzivo, antenna ye "millimeter wave horn" inogona kushandiswa kuona zvinangwa muma "radar systems".
4. Mimwe minda: Antena yeMm wave horn inewo mashandisirwo muindasitiri, masisitimu ekutora data nekutarisa (SCADA), uye zvinangwa zvesainzi nezvekurapa, zvakaita sekutaurirana kusina waya pakati pekutenga data riri kure nemidziyo yekutarisa, pamwe nekugamuchira uye kutumira masaini mune zvimwe zviedzo zvesainzi.
Antenna yeYagi yave ichishandiswa zvakanyanya muminda yakawanda yekutaurirana isina waya nekuda kwechimiro chayo chiri nyore, mutengo wakaderera wekugadzira, uye mashandiro akanaka.

QualwaveZvishandiso zveYagi Antennas zvinofukidza huwandu hwemafrequency anosvika 173MHz. Tinopa maantenna akajairwa egain horn egain 7dBi, pamwe nemaantenna maviri epolarized horn akagadzirwa zvinoenderana nezvinodiwa nevatengi.
