ʻAntenna Pūkuniahi Waveguide ʻĀpana 3.95-5.85GHz Alapine (Frequency Range), Loaʻa 10dBi Typ RM-SWHA187-10

ʻO ka Sectoral Waveguide Horn Antenna kahi ʻano antenna microwave alapine kiʻekiʻe e pili ana i kahi ʻano waveguide. ʻO kona hoʻolālā kumu he ʻāpana waveguide huinahā i hoʻolaha ʻia i loko o kahi puka "pepeiao" ma kekahi ʻaoʻao. Ma muli o ka mokulele o ka flare, aia ʻelua ʻano nui: ka pepeiaohao sectoral E-plane (i hoʻolaha ʻia ma ka mokulele o ke kahua uila) a me ka pepeiaohao sectoral H-plane (i hoʻolaha ʻia ma ka mokulele o ke kahua magnetic).

ʻO ke kumu hana nui o kēia antenna ka hoʻololi mālie ʻana i ka nalu electromagnetic i hoʻopaʻa ʻia mai ke alakaʻi nalu i kahi ākea manuahi ma o ka puka flared. Hāʻawi kēia i ka hoʻohālikelike impedance kūpono a hoʻemi i ka noʻonoʻo ʻana. ʻO kāna mau pono nui e pili ana i ka directivity kiʻekiʻe (lobe nui haiki), ka loaʻa kiʻekiʻe, a me kahi ʻano maʻalahi a paʻa.

Hoʻohana nui ʻia nā antenna pepeiaohao waveguide sectoral i nā noi e pono ai ke ʻano kukuna i kāohi ʻia. Hoʻohana pinepine ʻia lākou ma ke ʻano he mau pepeiaohao hānai no nā antenna reflector, i nā ʻōnaehana kamaʻilio microwave relay, a no ka hoʻāʻo ʻana a me ke ana ʻana i nā antenna ʻē aʻe a me nā ʻāpana RF.
