E HOAKAKA ANO

ʻO nā mea hoʻohui crossguide ʻelua e pili ana i kahi ʻano o ke ala alakaʻi nalu, loaʻa iā ia ke ʻano o ka ʻaoʻao ʻelua.

ʻO ke ala alakaʻi nalu ʻelua mau alakaʻi nalu coplanar e kū pono ana kekahi i kekahi. Ke hiki aku ka nalu electromagnetic ma kekahi alakaʻi nalu a hele aku ma waena o kahi kuʻekuʻe, e hoʻouna ʻia ia i kekahi alakaʻi nalu. Ma kēia kaʻina hana, no ka loaʻa ʻana o kahi kihi ma waena o nā alakaʻi nalu, lawe ʻia kahi ʻāpana o ka ikehu i kahi alakaʻi nalu ʻē aʻe, a laila e loaʻa ai ka hui ʻana. Hiki i kēia ʻano hoʻoili ke hoʻouna i ʻelua mau ʻano orthogonal i ka manawa like, no laila he kiʻekiʻe o ka orthogonality ka mea hoʻohui kea nalu.

Noi:

Hoʻohana nui ʻia ka huahana i ke ana microwave, laʻana, ʻike mana kiʻekiʻe, nā ʻōnaehana hānai microwave, radar, kamaʻilio, hoʻokele, kamaʻilio satellite a me nā ʻōnaehana ʻē aʻe.
Ma ke kahua kamaʻilio, hiki ke hoʻohana ʻia nā mea hoʻohui keʻa hawewe e unuhi i nā hōʻailona microwave mai kahi alakaʻi nalu a hoʻohui iā lākou i kahi alakaʻi hawewe ʻē aʻe, e loaʻa ai nā pilina ma waena o nā kaha alapine like ʻole. No ka laʻana, ma nā ʻōnaehana kamaʻilio ukali, hiki ke hoʻohana ʻia nā mea hoʻohui keʻa alakaʻi nalu e hoʻohui i nā awa puka o nā mea hoʻonui i nā pae āpau, e hana pololei a hilinaʻi hoʻi ka hoʻouna ʻana i ka hōʻailona ma waena o nā pae. Eia kekahi, hiki ke hoʻohana ʻia nā mea hoʻohui keʻa hawewe e hana i nā hale ʻoihana ʻelua-dimensional a i ʻole ʻekolu-dimensional ma optics.

Nā hiʻohiʻona:

Loaʻa nā ʻano alakaʻi nalu maʻamau e like me ka rectangular, flat rectangular, medium flat rectangular, a me ke kuamoʻo pālua, nona nā hiʻohiʻona o ke kuhikuhi kiʻekiʻe, haʻahaʻa VSWR, pane haʻahaʻa haʻahaʻa, a me ka laulā hawewe conduction piha.

Kaʻaleʻaleʻahoʻolako i ka broadband a me ka mana kiʻekiʻe ʻelua mau alakaʻi crossguide couplers ma kahi ākea mai 5.38GHz a i 40GHz. Hoʻohana nui ʻia nā mea hoʻohui i nā noi he nui. ʻO nā mea maʻamau no ka nalu alakaʻi alakaʻi kiʻekiʻe he keleawe a me ka aluminika, me ka hoʻomaʻamaʻa ʻana i ka ʻili e like me ke kala kala, ka pā gula, ka nickel plating, passivation, a me ka conductive oxidation. Hiki ke hoʻopilikino ʻia nā ʻāpana o waho, flange, ʻano hui, nā mea, ka mālama ʻana i ka ʻili, a me nā kikoʻī uila o nā hui alakaʻi nalu e like me nā koi o ka mea hoʻohana.
