Log Periodic Antenna 6.5dBi Typ. Loaʻa, 0.1-2GHz Laulā Alapine RM-LPA012-6

ʻO ka antenna log-periodic he antenna broadband kū hoʻokahi nona ka hana uila, e like me ka impedance a me ke ʻano radiation, e hana hou i kēlā me kēia manawa me ka logarithm o ke alapine. ʻO kona ʻano hana maʻamau he pūʻulu o nā mea metala dipole o nā lōʻihi like ʻole, ʻo ia ka 交叉-pili i kahi laina hānai, e hana ana i kahi hiʻohiʻona geometric e hoʻomanaʻo ana i ka iwi iʻa.

ʻO kāna kumu hana e hilinaʻi nei i ka manaʻo "'āpana hana". Ma kahi alapine hana kiko'ī, ʻo kahi pūʻulu wale nō o nā mea me ka lōʻihi kokoke i ka hapalua o ka lōʻihi o ka nalu e hauʻoli maikaʻi a kuleana no ka radiation mua. Ke hoʻololi nei ke alapine, neʻe kēia ʻāpana hana ma ke ʻano o ka antenna, e hiki ai i kāna hana wideband.

ʻO ka pōmaikaʻi koʻikoʻi o kēia antenna ʻo kāna bandwidth ākea loa, hiki pinepine i ka 10: 1 a ʻoi aku paha, me ka hana paʻa ma waena o ka hui. ʻO kāna mau hemahema nui he ʻano paʻakikī a me ka loaʻa haʻahaʻa. Hoʻohana nui ʻia ia i ka hoʻokipa kīwī, ka nānā ʻana i ka spectrum band piha, hoʻāʻo Electromagnetic Compatibility (EMC), a me nā ʻōnaehana kamaʻilio e koi ana i ka hana wideband.
