He aha ka hana o kahi kānana antenna kaʻa
Youdaoplaceholder0 ʻO ka hana nui o ka kānana antenna kaʻa ʻo ia ke kāohi i ka hoʻopili electromagnetic, hoʻomaikaʻi i ka maikaʻi o ka kamaʻilio a me ka ratio signal-to-noise . Hoʻomaikaʻi ka kānana i ka pale ʻana i ka hōʻailona a me ka ratio signal-to-noise ma ke kānana ʻana i nā ʻāpana alapine makemake ʻole, a laila e hōʻoia i ka paʻa a me ka hilinaʻi o nā ʻōnaehana kamaʻilio .
Hana kikoʻī
Youdaoplaceholder0 Kāohi electromagnetic interference : Hiki i ke kānana antenna automotive ke kānana pono i ka hoʻopili electromagnetic, ʻoi aku ka nui o nā hōʻailona interference kiʻekiʻe, e pale aku iā lākou mai ke komo ʻana i ka mana mana a me ka hoʻohaumia ʻana i ke kaiapuni electromagnetic. Kōkua kēia i ka hoʻomau pono ʻana o nā lako kamaʻilio a pale i ka hoʻopau ʻana i ke kamaʻilio a i ʻole ka hewa ʻikepili i hoʻokumu ʻia e ka hoʻopili electromagnetic .
Youdaoplaceholder0 E hoʻomaikaʻi i ka maikaʻi kamaʻilio : Ma ke kānana ʻana i nā hōʻailona hoʻopilikia kiʻekiʻe, hiki i ka kānana ke hoʻomaikaʻi i ka ratio signal-to-noise o ka mea hoʻokipa, e hōʻoiaʻiʻo ana i nā hōʻailona kamaʻilio paʻa. He mea koʻikoʻi kēia i nā lako kamaʻilio i kau ʻia i ke kaʻa, ʻoi aku hoʻi i nā wahi leo kiʻekiʻe, hiki ke hōʻemi pono i ka pae walaʻau hope a hoʻomaikaʻi i ka maikaʻi kamaʻilio .
Youdaoplaceholder0 Hoʻonui hōʻailona : Kōkua pū nā kānana i ka hoʻomaikaʻi ʻana i ka hoʻouna ʻana i nā hōʻailona pono, e hōʻoiaʻiʻo ana i ka hoʻokipa ʻoi aku ka paʻa a me ka pololei no nā hāmeʻa e like me nā ʻōnaehana hoʻokele a me nā lekiō. HE CRUCIAL kēia no ka hana maʻamau o ka ʻōnaehana hoʻokele kaʻa a me ka RADIO .
Hoʻolālā a me ka loina hana
ʻO nā kānana antenna automotive ka mea maʻamau i nā capacitors, inductors a me nā resistors. Ma ka hoʻohana pono ʻana i ko lākou ʻano o ka hele ʻana i nā alapine kiʻekiʻe a me ka pale ʻana i nā alapine haʻahaʻa, kuhikuhi lākou i nā ʻauwaʻa alapine kiʻekiʻe i loko o ka lepo a i ʻole uea kūʻokoʻa, no laila e noʻonoʻo ai a e komo ai i nā hōʻailona interference. Eia kekahi, hiki i ka kānana ke hoʻopaʻa hou i ka interference electromagnetic ma o nā ʻano ʻenehana e like me ka kānana multistage a me ka pōʻai uku no ka loulou alakaʻi .
ʻO Youdaoplaceholder0 Automotive antenna filter he mea ia i hoʻohana ʻia i nā ʻōnaehana antenna automotive, nona ka hana nui e kānana i nā hōʻailona makemake ʻole e hōʻoia i ka loaʻa ʻana o ka antenna i nā hōʻailona makemake. Hoʻomaikaʻi nā kānana i ka maikaʻi o ka hōʻailona loaʻa a me ka paʻa ʻana o ka ʻōnaehana ma o ka ʻae ʻana i nā alapine kikoʻī o ka hōʻailona e hele ma ke kaomi ʻana i nā alapine ʻē aʻe.
Nā ʻano a me nā hana o nā kānana antenna automotive
Youdaoplaceholder0 kānana haʻahaʻa haʻahaʻa : ʻAe i nā hōʻailona ma lalo o kahi alapine ʻoki ʻia e hele a poloka i nā hōʻailona ma luna o kēlā alapine.
Youdaoplaceholder0 kānana High-pass : Hoʻopaʻa i nā hōʻailona ma lalo o kahi alapine ʻoki ʻia a hiki i nā hōʻailona ma luna o kēlā alapine ke hala.
Youdaoplaceholder0 Kāna Band-pass : ʻAe i nā hōʻailona o kekahi pūʻulu e hele a hoʻopaʻa i nā hōʻailona o nā pūʻulu ʻē aʻe.
Youdaoplaceholder0 band-stop kānana : Hoʻopaʻa i nā hōʻailona mai kahi hui a hiki i nā hōʻailona mai nā hui ʻē aʻe ke hele.
ʻO nā hiʻohiʻona noi a me ke koʻikoʻi o nā kānana antenna automotive
Hoʻohana nui ʻia nā kānana antenna automotive i nā ʻōnaehana uila uila like ʻole, ʻoi aku hoʻi i nā antenna automotive automotive. ʻAʻole ʻoluʻolu wale kēia hoʻolālā akā hoʻemi pono i ka pale ʻana i ka makani. I kēia manawa, hiki i ka kānana i kūkulu ʻia ke kānana i ka interference electromagnetic pono ʻole, e hōʻoia i ka hana paʻa o nā lako kamaʻilio. No ka laʻana, he mea koʻikoʻi nā kānana i nā ʻāpana koʻikoʻi e like me ka hoʻokele engine a me nā ʻōnaehana braking e hōʻoia i kēia mau ʻōnaehana i ʻoi aku ka hilinaʻi a hoʻomaikaʻi i ka palekana kaʻa .
ʻO ke kumu hoʻolālā a me nā ʻāpana ʻenehana o nā kānana antenna automotive
ʻO ke kumu hoʻolālā o nā kānana antenna automotive e pili ana i ka manaʻo electromagnetic a me ka hoʻolālā kaapuni, a maʻamau i haku ʻia me nā capacitors, inductors a me nā resistors. ʻO kāna mau ʻenehana nui e pili ana i ke alapine waena, ke alapine ʻoki ʻoki, ka bandwidth passband, ka hoʻokomo ʻana, ripple, in-band wave, in-band standing wave ratio, return loss, stopband suppression degree, lohi a me ka in-band phase linearity, etc.
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 iā mākou inā makemake ʻoe i ia mau huahana.
ʻO Zhuo Meng Shanghai Auto Co., Ltd. ua kūpaʻa e kūʻai aku i nā ʻāpana kaʻa MG&750 e kuai.
