Ka hana o ke kānana antenna kaʻa
ʻO nā hana nui o ka kānana antenna kaʻa e komo pū me kēia mau ʻano:
ʻO Youdaoplaceholder0 Kānana hōʻailona a me ka hoʻopau ʻana i nā mea hoʻopilikia : Hiki i nā kānana antenna kaʻa ke kānana i nā ʻāpana alapine i makemake ʻole ʻia, e hoʻomaikaʻi ana i ke kū'ē ʻana i nā mea hoʻopilikia hōʻailona a me ka lakio signal-to-noise. ʻO ke ʻano kēia e hōʻoiaʻiʻo ana i ka hala ʻana o nā hōʻailona pono me ka hoʻopau ʻana i nā hōʻailona alapine i makemake ʻole ʻia, no laila e hōʻemi ana i nā mea hoʻopilikia kamaʻilio a hoʻomaikaʻi i ka maikaʻi o ke kamaʻilio .
ʻO Youdaoplaceholder0 E hoʻomaikaʻi i ka maikaʻi o ke kamaʻilio ʻana : Ma ka kānana ʻana i nā ʻāpana alapine i makemake ʻole ʻia, hōʻoia nā kānana i ka hoʻoili maʻalahi ʻana o nā hōʻailona ma nā alapine kikoʻī, a laila e hoʻomaikaʻi ana i ka maikaʻi o ke kamaʻilio ʻana. He mea nui loa kēia i nā ʻōnaehana hana hōʻailona alapine lekiō o nā kikowaena kumu a me nā lako terminal e hōʻoia i ka hoʻoili maopopo a hilinaʻi hoʻi .
ʻO Youdaoplaceholder0 E hōʻemi i ka hoʻopilikia electromagnetic : Hiki i nā kānana ke hoʻēmi nui i nā hōʻailona hoʻopilikia electromagnetic a pale iā lākou mai ke komo ʻana i ka pūnaewele mana, no laila e pale ana i ke kaiapuni electromagnetic mai ka haumia. He mea nui loa kēia no ka pale ʻana i ka hoʻopilikia electromagnetic mai ka hoʻopilikia ʻana i nā mea uila ʻē aʻe .
ʻO Youdaoplaceholder0 Hoʻomaikaʻi i ka pololei o ka loiloi : Ma nā noi e like me ka loiloi spectrum, hiki i nā kānana ke hoʻomaikaʻi i ka pololei o ka loiloi ma ke koho ʻana i kahi alapine kikoʻī no ka loiloi. ʻOi aku ka pololei o ka hana ʻana i ka hōʻailona a hiki ai ke hoʻomaopopo maikaʻi i nā ʻano a me nā waiwai o ka hōʻailona .
ʻO Youdaoplaceholder0 Laʻana noi kikoʻī : Hoʻohana nui ʻia nā kānana kikoʻī kiʻekiʻe i nā huahana antenna kaʻa shark fin. ʻAʻole wale kēia ʻano antenna he ʻano nani a ikaika hoʻi, akā hoʻohui pū i nā hana he nui e like me FM, GPS a me GSM. ʻO ka hoʻohana ʻana i nā kānana kikoʻī kiʻekiʻe e hiki ai i ka antenna ke hana i nā hōʻailona like ʻole me ka maikaʻi a hōʻoia i ka maikaʻi o ke kamaʻilio ʻana .
ʻO ka kānana antenna kaʻa ʻo Youdaoplaceholder0 he kānana i hoʻolālā kūikawā ʻia no nā antenna kaʻa, nona ka hana nui e kānana i nā hōʻailona alapine i makemake ʻole ʻia e hōʻoia i ka loaʻa ʻana o nā hōʻailona i makemake ʻia i ka antenna.
Ka Wehewehena a me ka Hana
ʻO ka kānana antenna kaʻa he ʻāpana uila, i hoʻokomo pinepine ʻia ma luna a kokoke paha i kahi antenna kaʻa, i hoʻohana ʻia e kānana i nā hōʻailona alapine i makemake ʻole ʻia. ʻO kāna hana nui ka hōʻemi ʻana i ka walaʻau a me ke komo ʻana i ka hōʻailona, e hōʻoia i ka maikaʻi o ka hōʻailona i loaʻa, a pēlā e hoʻonui ai i ka hana a me ke kūpaʻa o nā lako kamaʻilio.
ʻAno a me ke kumumanaʻo hana
Hana ʻia nā kānana antenna kaʻa me nā capacitors, inductors a me nā resistors, a hoʻohana i nā ʻano uila o kēia mau ʻāpana e ʻae koho a hoʻēmi paha i nā hōʻailona o nā alapine kikoʻī. ʻAe ia i nā hōʻailona o nā alapine kikoʻī e hele ma waena o ka wā e kāohi ana i nā alapine i makemake ʻole ʻia, no laila e hoʻoponopono ana i ka pilikia o ka hoʻopilikia hōʻailona ma waena o nā hui alapine like ʻole a me nā ʻōnaehana kamaʻilio.
Nā hiʻohiʻona noi
Hoʻohana nui ʻia nā kānana antenna kaʻa i nā mea kamaʻilio kaʻa like ʻole, me nā lekiō i kau ʻia i ke kaʻa, nā ʻōnaehana hoʻokele GPS, nā modula kamaʻilio uea ʻole, a me nā mea ʻē aʻe. Hōʻoiaʻiʻo ia i ka hana paʻa o kēia mau mea i kahi ʻano electromagnetic paʻakikī, hoʻemi i ka hoʻopilikia waho a hoʻomaikaʻi i ka maikaʻi o ka loaʻa ʻana o nā hōʻailona.
Hiki ke hana ʻia ka hemahema o ka kānana antenna kaʻa e nā kumu like ʻole, ʻo ia hoʻi kēia mau mea:
ʻO Youdaoplaceholder0 Poino kino : Hiki ke hāʻule nā ʻāpana i loko o ke kānana (e like me nā capacitors, inductors, resistors) ma muli o ka poino kino, e hopena ana i ka hana kānana maikaʻi ʻole a i ʻole ka hāʻule piha .
ʻO ka loli o ka mahana : ʻO nā loli hana o ke kānana ma nā mahana like ʻole e hana ai i ka pane alapine maʻamau ʻole a i ʻole ka neʻe ʻana o ka mahana, e hoʻopilikia ana i ka hopena kānana .
ʻO Youdaoplaceholder0 Impedance mismatch : Inā ʻaʻole kūlike ka impedance input a output paha o ke kānana me ko ka ʻōnaehana, e hōʻeha ia i ka nalowale ʻana o ka hōʻailona a i ʻole ka noʻonoʻo ʻana, e hoʻopilikia ana i ka hana o ka ʻōnaehana .
ʻO Youdaoplaceholder0 Ka hemahema mīkini : Inā ua hōʻino ʻia ka hale kānana a wehe paha nā mea hoʻohui, hiki ke hana i ka emi ʻana o ka hana kānana a i ʻole ka hemahema piha .
ʻAno ʻike hewa
Youdaoplaceholder0 Hoʻāʻo hana uila : Hiki ke hoʻohana ʻia ka hoʻāʻo hana uila e ʻike ai inā he maʻamau ke kū'ē, ka capacitance a me nā palena ʻē aʻe o ke kānana, no laila e hoʻoholo ai inā he mau pilikia e like me nā kaapuni pōkole a i ʻole nā kaapuni hāmama .
Nānā X-ray Youdaoplaceholder0 : Hiki ke hoʻohana ʻia kahi ʻōnaehana nānā X-ray e ʻike ai inā he mau mea haole a i ʻole nā hōʻino kūkulu i loko o ke kānana, e kōkua ana i ka hoʻoholo ʻana i ke kumu o ka hewa .
ʻO Youdaoplaceholder0 Ka nānā ʻana i ka ʻāpana metallographic : Ma o ka nānā ʻana i ka ʻāpana metallographic, hiki ke nānā ʻia ke ʻano kūloko a me nā mea o ke kānana, e hoʻoholo hou ana i ke kumu o ka hewa .
Nā ʻano hana hoʻoponopono pilikia
Youdaoplaceholder0 E hoʻololi i nā ʻāpana i hōʻino ʻia : Inā ʻike ʻia ua hōʻino ʻia kahi ʻāpana i loko o ke kānana, hiki ke hoʻololi ʻia ka ʻāpana i hōʻino ʻia e hoʻihoʻi i ka hana maʻamau o ke kānana .
Youdaoplaceholder0 E hoʻoponopono i ka hoʻolālā : No ka mismatch impedance a i ʻole ka drift mahana i hoʻokumu ʻia e nā pilikia hoʻolālā, hiki ke hoʻomaikaʻi ʻia ka hana o ke kānana ma ka hoʻoponopono ʻana i nā palena hoʻolālā .
Youdaoplaceholder0 Hoʻoponopono i nā hewa mīkini : No nā hewa mīkini, hiki iā ʻoe ke hoʻoponopono i ka hale i hōʻino ʻia a hoʻopaʻa paha i nā ʻāpana wehe e hōʻoia i ka hana paʻa o ke kānana .
?Inā makemake ʻoe e ʻike hou aku, e hoʻomau i ka heluhelu ʻana i nā ʻatikala ʻē aʻe ma kēia pūnaewele!
E ʻoluʻolu e kelepona mai iā mākou inā makemake ʻoe i kēlā mau huahana.
ʻO Zhuo Meng Shanghai Auto Co., Ltd. ua kūpaʻa i ke kūʻai aku ʻana i nā ʻāpana kaʻa MG&750 e kūʻai.
