Hoʻokaʻawale ʻana i nā Antenna
Ua hoʻomohala ʻia nā antenna like ʻole no nā noi like ʻole, i hōʻuluʻulu ʻia penei:
Antenna uwea
e komo pū me nā antenna dipole, nā antenna monopole, nā antenna loop, nā antenna dipole casing, nā antenna array Yagi-Uda a me nā hale pili ʻē aʻe.He haʻahaʻa ka loaʻa ʻana o nā antenna uea a hoʻohana pinepine ʻia ma nā alapine haʻahaʻa (paʻi i ka UHF).ʻO kā lākou mau pōmaikaʻi he māmā ke kaumaha, ke kumu kūʻai haʻahaʻa a me ka hoʻolālā maʻalahi.
Antenna puka
e komo pū ana me ke alakaʻi hawewe hāmama, ʻehā a i ʻole poʻe pōʻai waha lāʻau pū, mea hōʻike a me nā lens.ʻO nā antenna aperture ka antenna maʻamau i hoʻohana ʻia ma ka microwave a me nā alapine mmWave, a loaʻa iā lākou ka loaʻa haʻahaʻa a kiʻekiʻe.
Antenna i pai ʻia
e hoʻokomo i nā pahu i paʻi ʻia, nā dipoles i paʻi ʻia a me nā antenna kaapuni microstrip.Hiki ke hana ʻia kēia mau antenna e nā ʻano photolithographic, a hiki ke hana ʻia nā mea radiating a me nā kaʻa hānai e pili ana i kahi substrate dielectric.Hoʻohana pinepine ʻia nā antenna i paʻi ʻia ma ka microwave a me ka millimeter wave frequencies a maʻalahi e hoʻonohonoho ʻia e loaʻa ai ka waiwai kiʻekiʻe.
ʻO nā antenna hoʻonohonoho
Aia nā mea antenna i hoʻonohonoho mau ʻia a me kahi pūnaewele hānai.Ma ka hoʻoponopono ʻana i ka amplitude a me ka māhele māhele o nā mea hoʻonohonoho, hiki ke hoʻomalu ʻia nā hiʻohiʻona hiʻohiʻona e like me ke kihi kuhikuhi ʻana o ka beam a me ka pae lobe ʻaoʻao o ka antenna.ʻO kahi antenna array koʻikoʻi ka antenna array phased (phased array), kahi i hoʻohana ʻia ai kahi mea hoʻololi hoʻololi e ʻike ai i ke kuhikuhi nui o ka antenna i nānā ʻia.
