A Antenna Pepeiao Polarization Pōʻaihe ʻano kūikawā o ka antenna microwave i hoʻolālā ʻia e hoʻolaha a loaʻa paha i nā nalu electromagnetic me ka polarization circular. ʻAʻole e like me ka polarization linear, kahi e oscillates ai ke kahua uila i loko o kahi mokulele hoʻokahi, hōʻike ka polarization circular i kahi vector kahua uila e wili mau ana i ka wā e laha ai ka nalu, e hahai ana i kahi ʻano helical. Hāʻawi kēia ʻano kū hoʻokahi i nā pono koʻikoʻi i nā ʻano kamaʻilio paʻakikī a me nā ʻano ʻike.
Nā Pōmaikaʻi Koʻikoʻi o ka Polarization Circular
1. Palekana i ka Polarization Misalignment
I loko o nā ʻōnaehana polarization linear, pono e hoʻonohonoho pono ʻia nā antennas transmitter a me ka mea loaʻa i loko o kā lākou mau mokulele polarization e pale aku i ka nalowale ʻana o ka hōʻailona. Hoʻopau ka polarization circular i kēia koi. Mālama kahi nalu polarized circular i ka ikaika hōʻailona mau me ka nānā ʻole i ke kuhikuhi ʻana o ka antenna loaʻa—he pono koʻikoʻi no nā kamaʻilio ukali kelepona, kahi e hoʻololi mau ai ka neʻe ʻana o ke kaʻa i ke ʻano o ka antenna.
2. Hoʻēmi ʻana i ke Kūʻē Multipath
Ke hōʻike ʻia kahi nalu polarized poepoe mai kahi ʻili (e like me ka wai, nā hale, a i ʻole ka honua), e hoʻohuli ʻia kona lima polarization (e laʻa, lilo ka lima ʻākau i lima hema). ʻO nā antenna hoʻokipa i hoʻolālā ʻia no ka lima hoʻokahi e hōʻole maoli i ka lima ʻē aʻe, e hoʻopau pono ana i nā hōʻailona i hōʻike ʻia e hoʻoulu ai i ka mae ʻana o nā ala he nui. He waiwai nui kēia waiwai i nā mea hoʻokipa GPS a me nā loulou kamaʻilio kūlanakauhale.
3. Ke komo ʻana ma o nā hopena lewa
Hōʻike ka polarization pōʻai i ke kū'ē kiʻekiʻe loa i ka hoʻohuli ʻana o Faraday—kahi hanana kahi e hoʻohuli ai ke kahua magnetic o ka Honua i ka mokulele polarization o nā nalu polarized linearly e hele ana ma o ka ionosphere. Ma ka hoʻopau ʻana i ka ʻike i ka hoʻohuli polarization, hōʻoia ka polarization pōʻai i ka hoʻoili hōʻailona paʻa i nā loulou satelite-i-ka-honua a me nā kamaʻilio ākea hohonu.
4. Hoʻonui ʻia ka hana i ka wā ʻino
ʻO ka ua, ka noe, a me ka hau e emi ai ka emi ʻana o nā nalu polarized circular i hoʻohālikelike ʻia me ka polarization linear ma kekahi mau alapine (frequencies), e lilo ana ka polarization circular i koho makemake ʻia no nā ʻōnaehana radar a me nā loulou kamaʻilio e hana ana ma nā wahi me ka ua nui.
Hoʻokō ʻana o ka Antenna Pepeiao
Hoʻokō pinepine ʻia ka polarization pōʻai i loko o nā antenna pepeiaohao ma o nā polarizers i hoʻohui ʻia—nā ʻano mechanical e like me nā dielectric slabs, corrugations, a i ʻole nā polarizers septum i kau ʻia i loko o ka hānai waveguide. Hoʻololi kēia mau ʻāpana i ka input polarized linearly i ka output polarized circularly me ka maʻemaʻe kiʻekiʻe a me ka pohō hoʻokomo haʻahaʻa.
Nā Hoʻohana Maʻamau
•Kamaʻilio Satellite：Hiki i nā kikowaena honua a me nā antennas spaceborne ke hilinaʻi i ka polarization circular e mālama i ke kūpaʻa o ka loulou me ka neʻe ʻana o ka satellite a me nā hopena lewa.
•Nā ʻŌnaehana Satellite Hoʻokele Honua (GNSS): Hoʻohana nā hōʻailona GPS, BeiDou, a me Galileo i ka polarization pōʻai e hōʻoia i ke kūlana hilinaʻi ma nā awāwa kūlanakauhale a me nā wahi waiwai i nā ala he nui.
•Nā ʻŌnaehana Radar：Loaʻa ka pōmaikaʻi o ka radar aniau a me ka radar hahai pahuhopu mai ka hiki o ka polarization pōʻai ke hoʻokaʻawale ma waena o ka ua a me nā pahuhopu maoli.
•Kaua Uila & Nānā Hou: Hiki i ka polarization pōʻai ke hoʻoikaika i nā mana intercept me ka nānā ʻole i ke kūlana polarization o ka hōʻailona pahuhopu.
•RFID & Hoʻoili Mana Uea ʻole: Hōʻoia i ka kamaʻilio kūlike me nā lepili ma nā kuhikuhi kaulele ʻole.
Hōʻike nā antenna pepeiaohao polarization poepoe i kahi ʻenehana makua akā e ulu mau ana, e hāʻawi ana i ka paʻa kūlike ʻole i nā wahi hoʻolaha honua maoli.RFMiso, hoʻohui mākou i ka ʻenekinia precision me ka mana polarization holomua e hāʻawi i nā hoʻonā hana kiʻekiʻe i hana ʻia no nā noi koi nui loa ma ka aerospace, pale, a me nā kamaʻilio.
