Nā antenna i hoʻohana pinepine ʻia | Hoʻolauna i ʻeono ʻano like ʻole o nā antenna pepeiaohao

ʻO ka antenna pepeiaohao kekahi o nā antenna i hoʻohana nui ʻia me ke ʻano maʻalahi, ka laulā alapine (frequency) ākea, ka mana nui a me ka loaʻa kiʻekiʻe.Nā antenna pepeiaohaohoʻohana pinepine ʻia e like me nā antenna hānai i nā astronomy radio nui, ka nānā ʻana i nā ukali, a me nā antenna kamaʻilio. Ma waho aʻe o ka lawelawe ʻana ma ke ʻano he hānai no nā reflectors a me nā lens, he mea maʻamau ia i nā phased arrays a lawelawe ma ke ʻano he kūlana maʻamau no ka calibration a me nā ana loaʻa o nā antennas ʻē aʻe.

Hoʻokumu ʻia kahi antenna pepeiaohao ma ka wehe mālie ʻana i kahi alakaʻi nalu ʻehā a i ʻole kahi alakaʻi nalu pōʻai ma ke ʻano kikoʻī. Ma muli o ka hoʻonui mālie ʻana o ka ʻili waha alakaʻi nalu, ua hoʻomaikaʻi ʻia ka hoʻohālikelike ʻana ma waena o ke alakaʻi nalu a me ka hakahaka manuahi, e hoʻemi ana i ka coefficient reflection. No ke alakaʻi nalu ʻehā i hānai ʻia, pono e hoʻokō ʻia ka hoʻoili ʻano hoʻokahi e like me ka hiki, ʻo ia hoʻi, ʻo nā nalu TE10 wale nō i hoʻouna ʻia. ʻAʻole wale kēia e hoʻopaʻa i ka ikehu hōʻailona a hoʻemi i ka pohō, akā pale pū kekahi i ka hopena o ka hoʻopilikia inter-mode a me ka hoʻopuehu hou ʻana i hoʻokumu ʻia e nā ʻano he nui. .

Wahi a nā ʻano hana hoʻolaha like ʻole o nā antenna pepeiaohao, hiki ke hoʻokaʻawale ʻia lākou i lokonā antenna pepeiaohao ʻāpana, nā antenna pepeiaohao pyramid,nā antenna pepeiaohao conical, nā antenna pepeiaohao corrugated, nā antenna pepeiaohao i hoʻopaʻa ʻia, nā antenna pepeiaohao multi-mode, a pēlā aku. Ua wehewehe ʻia kēia mau antenna pepeiaohao maʻamau ma lalo nei. Hoʻolauna pākahi
