Butler Matrix

ʻO kahi Butler matrix kahi ʻano o ka beamforming network i hoʻohana ʻia i nā antenna arrays a me nā ʻōnaehana array phased.ʻO kāna mau hana nui:

● Hoʻokele kaola - Hiki iā ia ke hoʻokele i ke kaola antenna i nā kihi ʻokoʻa ma ka hoʻololi ʻana i ke awa hoʻokomo.ʻAe kēia i ka ʻōnaehana antenna e nānā uila i kona kukuna me ka ʻole o ka hoʻoneʻe kino ʻana i nā antenna.
● Ka hoʻokumu ʻana i nā kaola he nui - Hiki iā ia ke hānai i kahi ʻano antenna ma ke ʻano e hana ai i nā kaola he nui i ka manawa like, e kuhikuhi ana kēlā me kēia ma kahi ʻaoʻao ʻē aʻe.Hoʻonui kēia i ka uhi a me ka naʻau.
● Hoʻokaʻawale ʻana i ke kukui – Hoʻokaʻawale ia i kahi hōʻailona hoʻokomo i loko o nā awa puka he nui me nā pilina kikoʻī.Hiki i kēia ke hana i nā antenna i hoʻohui ʻia i nā kaola kuhikuhi.
● Ka hui pū ʻana o ka lāʻau - Ka hana pānaʻi o ka hoʻokaʻawale ʻana i ke kukui.Hoʻohui ia i nā hōʻailona mai nā mea antenna he nui i hoʻokahi huahana me ka loaʻa kiʻekiʻe.

Hoʻokō ka Butler matrix i kēia mau hana ma o kāna ʻano o nā mea hoʻohui hybrid a me nā mea hoʻololi manawa paʻa i hoʻonohonoho ʻia i kahi hoʻolālā matrix.ʻO kekahi mau waiwai nui:

● ʻO ka neʻe ʻana o ka pae ma waena o nā awa puka e pili ana he 90 degere (he hapaha lōʻihi hawewe).
● Ua kaupalena ʻia ka helu o nā kaola e ka helu o nā awa (N x N Butler matrix e hana i nā kukuna N).
● Hoʻoholo ʻia nā ʻōkuhi kukuna e ka matrix geometry a me ka phasing.
● Haʻahaʻa poho, passive, a me reciprocal hana.

No laila i ka hōʻuluʻulu ʻana, ʻo ka hana nui o kahi Butler matrix ʻo ia ka hānai ʻana i kahi antenna array ma ke ala e hiki ai i ka beamforming dynamic, beam steering, a me nā mana multi-beam ma o ka mana uila me nā ʻāpana ʻole.He ʻenehana hiki ke hoʻohana ʻia no nā arrays scan electronically a me nā radar array phased.

ʻO Concept Microwave kahi mea hoʻolako honua o ka butler matrix, e kākoʻo ana i ka hoʻāʻo MIMO multichannel a hiki i 8 + 8 antenna ports, ma luna o kahi ākea nui.
