ʻO ka antenna pepeiaohao loaʻa maʻamau he antenna planar i hana ʻia i ka papa metala, hoʻohana pinepine ʻia no ka hoʻoili ʻana a me ka loaʻa ʻana o nā hōʻailona microwave a me ka nalu millimeter.

ʻO ka maʻamau, he pepeiaohao waha metala huinahā a me kahi kihi alakaʻi me ka laulā i hoʻemi ʻia ma nā ʻaoʻao ʻelua. Hoʻouna ʻia ka hōʻailona nalu electromagnetic i loaʻa i ka waha pepeiaohao ma o ka mea i ʻōlelo ʻia ma luna. Ma muli o kona ʻano pepeiaohao i hoʻonui mālie ʻia, hiki ke hoʻonui ʻia ka hōʻailona a hiki ke hoʻomaikaʻi ʻia ka ʻike e loaʻa ana, a laila e loaʻa ai kahi hopena hana maikaʻi. Hiki iā ia ke hoʻopili i nā nalu electromagnetic i kahi kuhikuhi, a laila e hoʻonui ai i ka hopena o ka hoʻouna ʻana o nā hōʻailona. ʻO kona mau pono he ʻano maʻalahi, ka laulā o ke alapine (frequency band), ka lakio nalu kū haʻahaʻa haʻahaʻa (VSWR), ka mana mana nui, ka hoʻoponopono kūpono a me ka hoʻohana ʻana. Hiki i ke koho kūpono o ka nui o ka pepeiaohao ke loaʻa nā ʻano radiation maikaʻi.

Ma ke ʻano o nā noi, kūpono loa nā antenna pepeiaohao RF no ka hoʻāʻo ʻana i ka hana o nā antenna pepeiaohao microwave ʻē aʻe no ka mea he pālahalaha loa ko lākou mau piʻo lakio nalu loaʻa a me ke kū ʻana ma luna o ka laulā bandwidth. Ma ke ʻano laulā, hoʻohana ʻia nā antenna pepeiaohao nalu millimeter e like me nā antenna kuhikuhi i nā radar a me nā radiometer microwave; Hoʻohana ʻia ia ma ke ʻano he pepeiaohao hānai i nā ʻano antenna nui e like me ka antenna parabolic. I nā hoʻāʻo antenna ʻē aʻe, hoʻohana ʻia ia ma ke ʻano he calibration a me ka mea hoʻāʻo; I ke kamaʻilio ākea, hoʻohana ʻia ka antenna pepeiaohao rectangular i ke kamaʻilio ukali e hoʻomaikaʻi i ka maikaʻi o ke kamaʻilio a me ka mamao.

ʻO ka antenna pepeiaohao loaʻa maʻamau e pili ana i kahi antenna pepeiaohao broadband me ka loaʻa kiʻekiʻe mau ma luna o kahi laulā bandwidth ākea, nona ka hana paʻa, ka calibration pololei, a me ka maʻemaʻe polarization linear kiʻekiʻe. Hoʻohana nui ʻia ia ma ke ʻano he antenna maʻamau no ke ana ʻana i ka loaʻa antenna, he antenna hoʻouna kōkua no ke ana ʻana o ka antenna, he antenna loaʻa no ka ʻike ʻana i ka antenna, he antenna hoʻouna a loaʻa paha no nā jammers a me nā mea uila ʻē aʻe.

QualwaveHāʻawi ʻo Inc. i nā antenna pepeiaohao loaʻa maʻamau me kahi alapine (frequency) a hiki i 1100GHz. Loaʻa i ka hapa nui o nā huahana ʻehā mau koho loaʻa: 10dB, 15dB, 20dB, a me 25dB, a hiki ke hoʻopilikino ʻia e like me nā koi o ka mea kūʻai aku.
