TWANDIKIRE NONAHA

Antena ya Yagi ni antena ikora ku musozo igizwe na oscillator ikora (ubusanzwe ikora ku musozo), agace kagaragaza urumuri, n'abayobozi benshi bashinzwe urumuri bashyizwe hamwe. Mu myaka ya 1920, Hidetsugu Yagi na Taiki Uta bo muri Kaminuza ya Tohoku mu Buyapani bavumbuye iyi antena, izwi ku izina rya "Antena ya Yagi Uta" cyangwa "Antena ya Yagi".

Ibiranga

1. Icyerekezo gikomeye: Antena ifite icyerekezo cyiza kandi ishobora kwerekeza imiraba ya radiyo mu cyerekezo runaka. Icyerekezo ntarengwa cy'imirasire ni kimwe n'icy'umuyobozi, bigakuraho neza akajagari n'ibangamira mu cyerekezo kitari icyo umuntu ashaka.
2. Inyungu nyinshi: Ugereranyije na antene za dipole, antene ya horn ifite inyungu nyinshi kandi ishobora gufata neza ibimenyetso biri kure, bikanoza ubwiza n'ubuhanga bwo kwakira.
3. Imiterere yoroshye: igizwe n'udukoresho duto two gupima ikirere, udukoresho duto two kugarura ikirere, n'udukoresho twinshi duto two gupima ikirere dushyizwe hamwe, imiterere yayo iroroshye, ibikoresho byoroshye kubibona, igiciro ni gito, kandi ni oroheje, ikomeye, kandi yoroshye kuyigaburira.

Porogaramu

1. Ahantu ho gutumanaho: Antene ya RF ikoreshwa mu gutumanaho hakoreshejwe uburyo bwa shortwave na ultra shortwave, nko mu gutumanaho hakoreshejwe radiyo ikora kure, kandi ishobora no gukoreshwa nk'antene zo hanze mu gutera amajwi ya telefoni zigendanwa kugira ngo yongere amajwi ya telefoni zigendanwa. Ishobora kwagura urwego rwo gukwirakwiza no kongera imbaraga z'amajwi muri interineti ya Wi-Fi, ikwiriye guhuza inyubako ziri kure cyangwa kwagura urwego runini rwo gukwirakwiza.
2. Mu rwego rwo gusakaza no kureba televiziyo, antene ya microwave ikunze gukoreshwa nka antene yakira televiziyo, ishobora kwakira ibimenyetso bya televiziyo mu byerekezo runaka no kunoza uburyo bwo kwakira.
3. Umurima wa Radar: Bitewe n'icyerekezo cyawo n'imiterere yawo yo gukura, antene ya milimetero ishobora gukoreshwa mu kumenya intego muri sisitemu za radar.
4. Izindi nzego: Antene ya Mm wave horn ifite kandi porogaramu mu nganda, sisitemu yo kubona no gukurikirana amakuru (SCADA), ndetse n'intego za siyansi n'ubuvuzi, nko gutumanaho nta mashini zikoresha insinga hagati yo kubona amakuru ari kure n'ibikoresho byo kuyakurikirana, ndetse no kwakira no kohereza ibimenyetso mu bushakashatsi bumwe na bumwe bwa siyansi.
Antene ya Yagi yakoreshejwe cyane mu nzego nyinshi z'itumanaho ridafite insinga bitewe n'imiterere yayo yoroshye, ikiguzi gito cyo kuyikora, ndetse n'imikorere yayo myiza.

QualwaveIbikoresho bya Yagi Antena zitanga umuvuduko ugera kuri 173MHz. Dutanga antene zisanzwe za gain horn za gain 7dBi, hamwe na antene ebyiri zikozwe mu buryo bwa polarized horn hakurikijwe ibyo abakiriya bakeneye.
