ʻO Antenna, hiki ke hoʻohana ʻia no ka hoʻouna ʻana i nā hōʻailona a loaʻa i nā hōʻailona, hiki ke hoʻohuli ʻia, loaʻa ka pānaʻi, a hiki ke manaʻo ʻia he transducer, ʻo ia kahi mea hoʻopili ma waena o ke kaapuni a me ka lewa.Ke hoʻohana ʻia e hoʻouna i nā hōʻailona, ua hoʻohuli ʻia nā hōʻailona uila kiʻekiʻe i hana ʻia e ke kumu hōʻailona i nā hawewe electromagnetic i ka lewa a hoʻokuʻu ʻia i kekahi ʻaoʻao.Ke hoʻohana ʻia no ka loaʻa ʻana o nā hōʻailona, hoʻololi ʻia nā hawewe electromagnetic ma ke ākea i mau hōʻailona uila a hoʻouna ʻia i ka mea hoʻokipa ma o ke kaula.
Loaʻa i kēlā me kēia antenna kekahi mau hiʻohiʻona hiʻohiʻona i hiki ke wehewehe pono ʻia, hiki ke hoʻohana ʻia e loiloi i ka hana o ka antenna, me nā ʻāpana hiʻona uila a me nā ʻāpana ʻano mechanical.

Hoʻokaʻawale ʻana o ka antena
Hiki ke hoʻokaʻawale ʻia nā Antennas e like me nā ʻano like ʻole, ka nui:
Ka hoʻokaʻawale ʻana ma o ka hoʻohana ʻana: hiki ke hoʻokaʻawale ʻia i ka antenna kamaʻilio, antenna televise, antenna radar a pēlā aku
E like me ka hoʻokaʻawale ʻana o ka band frequency hana: hiki ke hoʻokaʻawale ʻia i nā antenna pōkole, nā antenna ultra-pōkole, antenna microwave a pēlā aku.
E like me ka hoʻokaʻawale ʻana o ka kuhikuhi: hiki ke hoʻokaʻawale ʻia i nā antenna omnidirectional, antenna directional, etc.
E like me ke ʻano hoʻohālikelike: hiki ke hoʻokaʻawale ʻia i nā antenna linear, planar antenna a pēlā aku
Antenna kuhikuhi: Ua kaupalena ʻia ka ʻaoʻao antenna i ka ʻaoʻao ākea o lalo o 360 degere.
Hiki ke hoʻohana pinepine ʻia nā antenna Omnidirectional no ka loaʻa ʻana / hoʻouna ʻana i nā hōʻailona ma nā ʻaoʻao āpau i ka manawa like.Makemake paha kēia inā pono e loaʻa a hoʻouna ʻia kahi hōʻailona ma nā ʻaoʻao āpau, e like me kekahi mau lekiō kuʻuna.Eia naʻe, he mau hihia i ʻike ʻia a i kaupalena ʻia ke kuhikuhi o ka hōʻailona.No ka laʻana, me ka lekiō lekiō, ua ʻike ʻia e loaʻa nā hōʻailona ma kahi kuhikuhi (mai ka lewa), ʻoiai ʻoi aku ka maikaʻi o nā antenna omni-directional i ke kiʻi ʻana i nā hōʻailona nāwaliwali mai nā hōkū.I kēia hihia, hiki ke hoʻohana ʻia kahi antenna kuhikuhi me ka loaʻa ʻana o ka antenna kiʻekiʻe no ka loaʻa ʻana o ka ikehu hōʻailona ma kahi kuhikuhi.
ʻO kahi hiʻohiʻona o kahi antenna kuhikuhi nui ʻo ka Yagi antenna.ʻO kēia mau ʻano antenna nā alapine i hoʻohana ʻia e hoʻouna / loaʻa i nā hōʻailona kamaʻilio ma nā mamao lōʻihi ke ʻike ʻia ke kuhikuhi o ka hōʻailona hoʻokomo a i ʻole ka pahuhopu.ʻO kahi hiʻohiʻona ʻē aʻe o kahi antenna kuhikuhi nui ʻo ka waveguide gain horn antenna.Hoʻohana pinepine ʻia kēia mau antenna no ka hoʻāʻo ʻana a me ke ana ʻana, e like me ke ana ʻana i ka hana o kekahi antenna ʻē aʻe, a i ʻole i ka wā e loaʻa ai / hoʻouna ʻana i nā hōʻailona ma kahi ʻoi aʻe o ke alapine hawewe.Hiki ke hana ʻia nā antenna kuhikuhi i loko o nā hoʻolālā papa pālahalaha māmā no ka hana maʻalahi ma nā substrate RF maʻamau e like me PCBS.Hoʻohana maʻamau ʻia kēia mau antenna pālahalaha i nā mea kūʻai aku a me nā kelepona ʻoihana no ka mea maʻalahi lākou i ka hana ʻana a māmā a liʻiliʻi.
