Antenna Puka Waveguide Sectoral 3.95-5.85GHz, Loaʻa 10dBi Typ RM-SWHA187-10

ʻO kahi Sectoral Waveguide Horn Antenna kahi ʻano o ka antenna microwave kiʻekiʻe e pili ana i kahi ʻano alakaʻi nalu. ʻO kāna hoʻolālā maʻamau he ʻāpana alakaʻi nalu ʻehā i hoʻāla ʻia i loko o kahi puka "horn"-like ma kekahi kihi. Ma muli o ka mokulele o ka lapalapa, aia ʻelua mau ʻano nui: ʻo ka E-plane sectoral horn (flared in the plane of the Electric field) a me ka H-plane sectoral horn (flared in the plane of the Magnetic field).

ʻO ke kumu hana mua o kēia antenna ʻo ka hoʻololi mālie ʻana i ka nalu electromagnetic i hoʻopaʻa ʻia mai ke alakaʻi nalu i kahi ākea ma o ka wehe ʻana. Hāʻawi kēia i ka hoʻohālikelike impedance kūpono a hōʻemi i ka noʻonoʻo. ʻO kāna mau pōmaikaʻi koʻikoʻi, ʻo ia ka kuhikuhi kiʻekiʻe (lobe nui haiki), ka waiwai kiʻekiʻe, a me kahi ʻano maʻalahi a paʻa.

Hoʻohana nui ʻia nā antenna puʻupuʻu puʻupuʻu Sectoral i nā noi e koi ana i ka hana ʻana i ka beam. Hoʻohana pinepine ʻia lākou e like me nā pū kīʻaha 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.
