ANT051 ʻEhā Element Spiral Antenna Array
| Alakai-mw | Introduction to Four Element Spiral Antenna Array |
Ke hoʻolauna nei ʻo Leader microwave tech.,(leader-mw) ka mea hou loa i ka ʻenehana antenna - hoʻopaʻa ʻia i nā ʻano stereo antenna helical helical. Hoʻolālā ʻia kēia ʻano ʻokiʻoki e hoʻololi i ke ʻano o kā mākou ʻike a hoʻohana ʻana i nā ʻōnaehana antenna, e hāʻawi ana i ka hana like ʻole a me ka versatility i kahi hoʻolālā paʻa a maikaʻi.
ʻO ka puʻuwai o kēia ʻano kipi ʻo ia ka mea helical antenna, i hoʻopili pono ʻia i loko o ka hoʻolālā papa tapered. Aia ka hale i ka ʻili luna a me nā ʻaoʻao he nui, ua pili kēlā me kēia me ka lihi o ka ʻili luna. Hoʻopili pū ʻia nā ʻaoʻao o nā ʻaoʻao e pili ana, e hana ana i kahi kahua paʻa ʻole a ikaika no nā mea antenna.
ʻO ka hoʻolālā kūʻokoʻa o ka hoʻolālā platform tapered e hiki ai i nā mea helical antenna ke kau ʻia ma luna a me nā ʻaoʻao, e hoʻonui i ka uhi a me ka hana. ʻO kēia hoʻonohonoho e hiki ai i ka array ke hoʻokuʻu i nā kaola he nui i ke ʻano stereoscopic, ma laila e hoʻonui ai i ka hiki ke hoʻokipa a me ka hoʻouna ʻana o ka ʻōnaehana antenna.
ʻO kekahi o nā hiʻohiʻona koʻikoʻi o ka ʻōnaehana tapered platform ʻo ia ke ʻano polygonal maʻamau o ka ʻili o luna, e hoʻomaikaʻi hou ana i ka hāʻawi like ʻana o nā mea antenna a hoʻopaʻa i ka hana holoʻokoʻa o ka array. ʻO kēia ka mea e hōʻoia i ka array hiki ke hāʻawi i ka ikaika hōʻailona kūpaʻa a hilinaʻi ma waena o nā ʻano noi a me nā kaiapuni.
