ʻO Horn antenna kekahi o nā antenna i hoʻohana nui ʻia me ka hoʻolālā maʻalahi, ka laulā ākea ākea, ka mana mana nui a me ka loaʻa kiʻekiʻe.Antenna kiwihoʻohana pinepine ʻia e like me nā antenna hānai i ka nui o ka lekiō astronomy, ka ukali ukali, a me nā antenna kamaʻilio.Ma waho aʻe o ka lawelawe ʻana ma ke ʻano he meaʻai no nā reflectors a me nā lens, he mea maʻamau ia i nā arrays phased a lawelawe ma ke ʻano maʻamau no ka calibration a loaʻa nā ana o nā antenna ʻē aʻe.
Hoʻokumu ʻia kahi antenna pū ma ka wehe ʻana i kahi alakaʻi nalu ʻehā a i ʻole kahi alakaʻi nalu pōʻai i kahi ʻano kikoʻī.Ma muli o ka hoʻonui lohi ʻana o ka waha o ka waha nalu, ua hoʻomaikaʻi ʻia ka hoʻohālikelike ʻana ma waena o ke alakaʻi nalu a me kahi ākea, e liʻiliʻi ai ka coefficient noʻonoʻo.No ke alakaʻi hawewe ʻāʻī, pono e hoʻokō ʻia ka hoʻouna ʻana i ke ʻano hoʻokahi e like me ka hiki, ʻo ia hoʻi, ʻo nā hawewe TE10 wale nō ke hoʻouna ʻia.ʻAʻole kēia e hoʻopaʻa wale i ka ikehu hōʻailona a hōʻemi i ka nalowale, akā pale pū kekahi i ka hopena o ka inter-mode interference a me ka hoʻopuehu hou ʻia e nā ʻano ʻano he nui..
E like me nā ʻano hoʻoili like ʻole o nā antenna horn, hiki ke hoʻokaʻawale ʻia inā antenna pū kani, nā antenna kiwi pyramid,nā antenna kiwi conical, nā antenna pepeiaohao corrugated, antenna horn ridged, multi-mode horn antennas, etc. Ua wehewehe ʻia kēia mau antenna kiwi maʻamau.Hoʻolauna pakahi
Antenna kīwila ʻāpana
E-plane horn antenna
Hana ʻia ka antenna puʻupuʻu E-plane me kahi alakaʻi hawewe rectangular i wehe ʻia ma kekahi kihi ma ke kuhikuhi o ke kahua uila.
Hōʻike ka kiʻi ma lalo nei i nā hopena hoʻohālikelike o ka antenna horn sector E-plane.Hiki ke ʻike ʻia ʻoi aku ka liiki o ka laula kaola o kēia kumu ma ka ʻaoʻao E-plane ma mua o ka ʻaoʻao H-plane, ʻo ia ke kumu o ka puka nui o ka E-plane.
H-plane horn antenna
Hana ʻia ka antenna horn ʻāpana H-plane me kahi alakaʻi hawewe rectangular i wehe ʻia ma kekahi kihi i ke kuhikuhi o ke kahua magnetic.
Hōʻike ka kiʻi ma lalo i nā hopena hoʻohālikelike o ka antenna horn sector H-plane.Hiki ke ʻike ʻia ʻoi aku ka liiki o ka laula kaola o kēia kumu ma ka ʻaoʻao H-plane ma mua o ka ʻaoʻao E-plane, ʻo ia ke kumu o ka puka nui o ka mokulele H.
ʻO nā huahana antenna horn RFMISO:
RM-SWHA187-10
RM-SWHA28-10
Pyramid Horn Antenna
Hana ʻia ka antenna puʻupuʻu pyramid me kahi alakaʻi nalu rectangular i wehe ʻia ma kekahi kihi ma nā ʻaoʻao ʻelua i ka manawa like.
Hōʻike ka kiʻi ma lalo nei i nā hopena hoʻohālikelike o kahi antena horn pyramidal.ʻO kāna mau hiʻohiʻona radiation ka hui pū ʻana o nā pū ʻāpana E-plane a me H-plane.
Antenna kiwi conical
Ke hoʻohālikelike ʻia ka ʻaoʻao hāmama o kahi alakaʻi nalu pōʻai, ua kapa ʻia ʻo ia he antenna horn conical.Aia ka antenna kiwi cone he puka pōʻai a elliptical paha ma luna.
Hōʻike ka kiʻi ma lalo i nā hopena hoʻohālikelike o ka antenna horn conical.
RFMISO conical horn antenna huahana:
RM-CDPHA218-15

ʻAntenna puʻupuʻu koʻikoʻi
ʻO ka antenna horn corrugated he antenna pū me ka ʻili o loko.Loaʻa iā ia nā mea maikaʻi o ka pā alapine ākea, haʻahaʻa cross-polarization, a me ka hana symmetry beam maikaʻi, akā paʻakikī kona ʻano, a he kiʻekiʻe ka paʻakikī a me ke kumukūʻai.
Hiki ke hoʻokaʻawale ʻia nā antenna horn corrugated i ʻelua ʻano: pyramidal corrugated horn antennas a me conical corrugated horn antennas.
RFMISO corrugated horn antenna huahana:
RM-CHA140220-22
Pyramidal corrugated horn antenna
Antenna kiwi koʻikoʻi conical
Hōʻike ka kiʻi ma lalo nei i nā hopena hoʻohālikelike o ka antenna kiwi conical corrugated.
Antenna kiwi riged
Ke ʻoi aku ka nui o ka hana ʻana o ka antenna horn maʻamau ma mua o 15 GHz, hoʻomaka ka ʻūhā hope e māhele a piʻi ka pae o ka lobe ʻaoʻao.Hiki ke hoʻonui i ka bandwidth, hoʻemi i ka impedance, hoʻonui i ka loaʻa, a hoʻonui i ka kuhikuhi ʻana o ka radiation.
Hoʻokaʻawale nui ʻia nā antenna horn ridged i ʻelua antenna horn a me ʻehā antenna horn.Hoʻohana ka mea ma lalo i ka antenna puʻupuʻu puʻupuʻu pyramidal maʻamau ma ke ʻano he laʻana no ka simulation.
Pyramid Double Ridge Horn Antenna
ʻO ka hoʻohui ʻana i ʻelua mau kuapuʻu ma waena o ka ʻaoʻao alakaʻi nalu a me ka ʻāpana wehe ʻana o ka pū, he antenna puʻupuʻu lua.Hoʻokaʻawale ʻia ka ʻāpana alakaʻi nalu i kahi lua kua a me kahi alakaʻi nalu.Hiki i ka lua hope ke kānana i nā ʻano ʻano kiʻekiʻe e hauʻoli i ka alakaʻi nalu.Hoʻemi ka hawewe nalu i ke alapine ʻoki ʻia o ka hoʻouna ʻana i ke ʻano kumu nui, no laila e hoʻokō ai i ke kumu o ka hoʻonui ʻana i ke alapine.
ʻOi aku ka liʻiliʻi o ka antenna horn ridged ma mua o ka antenna horn maʻamau i ka hui alapine like a ʻoi aku ka nui o ka loaʻa ma mua o ka antenna horn maʻamau i ka pūʻali alapine like.
Hōʻike ke kiʻi ma lalo nei i nā hopena hoʻohālikelike o ka antenna puʻupuʻu puʻupuʻu pyramidal.
Antenna horn multimode
Ma nā noi he nui, koi ʻia nā antenna horn e hāʻawi i nā ʻano like ʻole ma nā mokulele a pau, ʻokoʻa ka waena waena ma nā mokulele $E$ a me $H$, a me ka hoʻopaʻa ʻana i ka lobe ʻaoʻao.
Hiki ke hoʻonui i ka hopena hoʻohālikelike o kēlā me kēia mokulele a hoʻemi i ka pae lobe ʻaoʻao.ʻO kekahi o nā antenna puʻupuʻu multimode maʻamau ʻo ka ʻelua-mode conical horn antenna.
ʻElua ʻano Conical Horn Antenna
Hoʻomaikaʻi ka pū lua-mode cone i ke ʻano mokulele $E$ ma o ka hoʻokomo ʻana i ke ʻano kiʻekiʻe kiʻekiʻe o ke ʻano TM11, i loaʻa i kāna kumu hoʻohālike nā hiʻohiʻona axially symmetrical equalized beam.ʻO ke kiʻi ma lalo nei he kiʻi kikoʻī o ka puʻu ʻana o ke kahua uila aperture o ke ʻano nui TE11 mode a me ke ʻano kiʻekiʻe-ʻoi aku ka TM11 i loko o kahi alakaʻi nalu pōʻai a me kāna hoʻohele ʻana i ke kahua aperture.
ʻAʻole kū hoʻokahi ke ʻano hana hoʻokō o ka pū lua-mode conical.ʻO nā hana hoʻokō maʻamau, ʻo ia ka pūni Potter a me ka pū Pickett-Potter.
Hōʻike ka kiʻi ma lalo nei i nā hopena hoʻohālikelike o ka antenna horn conical horn ʻelua-mode Potter.
