Yagi Antenna ke adtenation anterna e felisitsoeng e le mofuta o sebetsang (hangata oscillator e sebetsang), mojaki oa pente le baqapi ba 'maloa ba etsang lintho tse' maloa ba hlophisitsoeng ba tšoana. Ka 1920s, patetsutu Yagi le Taiki Uta University Univesithing e qaqileng Antena "kapa ke" Yagi Antenna ".

Tšobotsi

1. Karolo e matla: Antentena e na le tataiso e ntle 'me e ka tsepamisa likelello tsa seea-le-moea ka tsela e tobileng. Tataiso e phahameng ka ho fetisisa ea radiation e tšoana le ea motsamaisi, ea hatellang sekoli le ho kena-kenana le tsela e sa lebelloang.
2. Tonakholo e phahameng
3. Sebopeho se bonolo: li-ossillators tse sebetsang, li-nkhono le bahanyetsi ba 'maloa ba iketsa, thepa e bobebe, e leng e bonolo ho e fepa.

Kopo

1. Mokhahlelo oa puisano: RF lenannntenta e sebelisitsoeng ha e futsanehileng le ultra E ka eketsa sebaka sa tšireletso mme e ntlafatse matla a lets'oa ka ho hokahanya meaho e hole kapa ho eketsa tšireletso e hole.
2 Hangata lebaleng la lihlekehleke tsa phatlalatso le thelevisheneng, li-microwave tsa thelevishene li sebelisoa e le thelevishene, e ka fumanang lipontšo tsa thelevishene, tse ka fumanang masela a thelevishene ka tataiso e tobileng le ho ntlafatsa moaho oa kamohelo.
3. Tšimo ea Radar: Ka lebaka la litšobotsi tsa eona tsa tataiso le ho fumana litšobotsi tsa millimeter wave
4. Masimo a mang :m wave Horn Altena le lits'ebeletso tsa data tse pakeng tsa boitlamo ba data le phetisetso litekong tse ling tsa mahlale.
Ateni Antenna o sebelisoa haholo masimong a puisano a se nang mohala e se nang mohala ka lebaka la sebopeho sa pounse e bonolo, litšenyehelo tse tlase tsa tlhahiso le tšebeliso e ntle.

PhelloPhepelo ea Yagi Antennas e koahela khafetsa ho fihlela ho 173mhz. Re fana ka litekanyetso tsa Horn Attenas tsa phaello ea 7dbi, hammoho le litlhokahalo tsa mananeo a halikiloeng ho latela litlhoko tsa bareki.
