ANT0025PO Antenna Log-manawa paʻa lima
| Alakai-mw | Introduction to Log-Hold Log-Periodic Antenna |
Ke hoʻolauna nei iā Cheng du leader mcrowave Tech.,(leader-mw) handheld log-periodic antenna, ka hopena hope loa no ka hoʻonui ʻana i ka ikaika o ka hōʻailona a me ka uhi ʻana ma ka laulā 800 a 9000 MHz. Hoʻolālā ʻia kēia antenna koʻikoʻi akā ikaika e kākoʻo i nā kelepona kelepona, PCS, LTE, 4G LTE a me Wifi/WiMAX, e lilo ia i mea hana pono no ka poʻe e makemake i nā kamaʻilio uea ʻole hilinaʻi a kiʻekiʻe.
Loaʻa ka antenna log-periodic paʻa i ka loaʻa ʻana o 6 dBi flat, e uhi ana iā L / S / C / X me ka pololei a me ka pololei, e hōʻoiaʻiʻo iā ʻoe e pili pū me nā wahi āu e noho ai. ʻO ka mea ʻokoʻa i kēia antenna ʻo kāna hoʻolālā log-periodic hiki ke hoʻololi ʻia, e hāʻawi ana i ka maʻalahi a me ka hiki ke hoʻokō i kāu mau pono kikoʻī a me kou kaiapuni.
Hoʻolālā ʻia no ka lōʻihi a me ka hana, ʻo ka antenna log-periodic antenna e hōʻike ana i kahi radome plastic molded ikaika kiʻekiʻe, haʻahaʻa haʻahaʻa e hiki ke kū i nā kūlana paʻakikī a hoʻomau i ka hāʻawi ʻana i ka hana koʻikoʻi. Hoʻohui hou ʻia kāna puʻupuʻu pistol rotating i ka maʻalahi a me ka maʻalahi o ka hoʻohana ʻana, e ʻae iā ʻoe e hoʻoponopono maʻalahi i ka antenna e hoʻomaikaʻi i ka hoʻokipa hōʻailona.

ʻO ka wehewehe makemakika o ka coefficient antenna K penei:
ʻO nā manaʻo o kēlā me kēia parameter penei:
E: ka ikaika o ke kahua ma ke kūlana spatial o ka antenna e loaʻa ana, ma ka ʻāpana o V/m;
V: ka waiwai uila i loaʻa e ke awa antenna e loaʻa ana, ma ka ʻāpana o V.
ʻO ke kumu helu helu o ka coefficient antenna i hōʻike ʻia ma ka logarithm penei:
Log-periodicDipoleAntenna hoʻohana
(1) Hoʻohana nui ʻia i ka puʻupuʻu hawewe ultra-pōkole, hiki ke hoʻohana ʻia e like me ka antenna kamaʻilio nalu pōkole a me ka nalu waena, nā antenna hoʻolaha hoʻolaha hawewe pōkole. Hiki ke hoʻohana ʻia nā antenna log-periodic e like me nā mea hānai no nā antennas reflector microwave. Hiki ke hoʻohana ʻia no ka lekiō amateur a me nā hana lekiō kamaʻāina, a me ka noiʻi ʻepekema a me ka nānā ʻana.
(2) Log-periodic Dipole Antenna, hiki iā lākou ke mālama i nā hiʻohiʻona radiation maʻamau ma luna o kahi ākea o nā alapine, e hoʻohana pono iā lākou i nā noi kahi e pono ai nā antennas e hana ma waena o nā alapine he nui me ka ʻole o nā hoʻololi nui a i ʻole nā hoʻololi.
