ʻO kahi kānana Dielectric he fiber optical e hoʻouna maʻalahi i hoʻokahi nalu nalu a hōʻike i nā mea ʻē aʻe e pili ana i ka Interference i loko o ka hale. Kāhea ʻia hoʻi kānana interference. Hoʻomaikaʻi nā ceramics hopena dielectric microwave i ka nui o nā mea hana a me ka paʻa paʻa o ka microwave integrated circuits. No kēia kumu, hoʻohana nui ʻia ia no nā kānana microwave a me nā papa kaapuni ma ke kahua kumu o ka kamaʻilio kelepona a me nā ʻōnaehana kamaʻilio ukali ma 5G.
ʻO ka ʻenehana 5G i hoʻomohala wikiwiki ʻia e lawe mai i kahi mākeke nui i ke kahua kahua 5G a me ka kānana dielectric no ke kahua kahua 5g.
Kumu Manaʻo
Hoʻopili ʻia kahi ʻano hoʻohālikelike o kahi kānana resonator dielectric [1] me ka hoʻohana ʻana i ka module Scattering parameters o HFWorks e hoʻoholo ai i kāna pass-band, ka attenuation i loko a i waho o ka band, a me ka puʻunaue kahua uila no nā alapine like ʻole. Hōʻike ka hopena i kahi kūlike kūpono me nā mea i hōʻike ʻia ma [2]. Loaʻa i nā kaula he conductor nalowale, a he Teflon i loko. Hāʻawi ʻo HF Works i ka hiki ke hoʻolālā i nā ʻāpana like ʻole ma nā ʻāpana 2D a me Smith Chart. Ma waho aʻe, hiki ke ʻike ʻia ke kahua uila i ka vector a me ka fringe 3D plots no nā alapine i aʻo ʻia.
Hoʻohālikelike
No ka hoʻohālikelike i ke ʻano o kēia kānana (hoʻokomo a hoʻihoʻi i ka nalowale ...), e hana mākou i kahi haʻawina Scattering Parameters, a kuhikuhi i ke alapine kūpono e hana ai ka antenna (i kā mākou hihia 100 mau alapine i hoʻohele like ʻia mai 4 GHz a 8 GHz. ).
Paʻa a me nā mea waiwai
Ma ka helu 1, ua hōʻike mākou i ke kumu hoʻohālike discretized o kahi kānana kaapuni dielectric me nā mea hoʻokomo coaxial a me nā mea hoʻohui. Hana nā dielectric discs ʻelua ma ke ʻano he resonator i hui pū ʻia e lilo ai ka mea holoʻokoʻa i kānana bandpass kiʻekiʻe.
Haawe/ Kaohi
Hoʻohana ʻia nā awa ʻelua ma nā ʻaoʻao o nā hui coaxial ʻelua. Hana ʻia nā ʻaoʻao lalo o ka pahu ea e like me nā Palena Uila Pono. Loaʻa ka waiwai i ka plane symmetry horizontal a no laila, pono mākou e hoʻohālike i ka hapalua. No laila, pono mākou e hoʻolaha i ka simulator HFWorks ma ke kau ʻana i kahi kūlana palena PEMS; inā he PECS a PEMS paha, e pili ana i ka orientation o ke kahua uila kokoke i ka palena o ka symmetry. Inā tangential, a laila ʻo PEMS; ina orthogonal alaila he PECS.
Meshing
Pono e hoʻopaʻa ʻia ka mesh ma nā awa a me nā maka PEC. ʻO ka hoʻopaʻa ʻana i kēia mau ʻili e kōkua i ka mea hoʻoponopono e hoʻomaʻemaʻe i kona pololei ma nā ʻāpana eddy, a e noʻonoʻo i kā lākou mau ʻano.
Nā hualoaʻa
Loaʻa nā ʻāpana like ʻole 3D a me 2D no ka hoʻohana ʻana, e pili ana i ke ʻano o ka hana a me ke ʻano o ka mea hoʻohana e makemake ai. Ke hana nei mākou i kahi simulation kānana, ʻo ka hoʻolālā ʻana i ka parameter S21 e like me ka hana intuitive.
E like me ka mea i ʻōlelo ʻia ma ka hoʻomaka ʻana o kēia hōʻike, hoʻolālā ʻo HFWorks i nā pihi no nā ʻāpana uila ma nā ʻāpana 2D a me Smith Charts. ʻOi aku ka maikaʻi o ka hope no nā pilikia pili, a ʻoi aku ka pili i ka wā e hana ai mākou i nā hoʻolālā kānana. Ke ʻike nei mākou ma ʻaneʻi ua loaʻa iā mākou nā kaha pass-band a hiki mākou i kahi kaʻawale nui ma waho o ka band.
Hoʻopili ʻia nā ʻāpana 3D no nā haʻawina scattering-parameters i nā ʻāpana ākea: ʻo nā kiʻi ʻelua e hōʻike ana i ka puʻunaue ʻana o ke kahua uila no ʻelua alapine (ʻo kekahi i loko o ka band a ʻo kekahi ma waho o ka band)
Hiki ke hoʻohālikelike ʻia ke kŘkohu me ka hoʻohana ʻana i ka mea hoʻoponopono resonance o HFWorks pū kekahi. Hiki iā mākou ke ʻike i nā ʻano like ʻole e like me kā mākou makemake. He mea maʻalahi ka loaʻa ʻana o ia ʻano haʻawina mai ka S-Parameter simulated study : HFWorks hiki ke kauo a hoʻokuʻu i nā erations e hoʻonohonoho koke i ka simulation resonance. Noʻonoʻo ka mea hoʻoponopono resonance i ka EM matrix o ke kumu hoʻohālike a hāʻawi i nā ʻano hoʻonā ʻano Eigen like ʻole. Ua kūpono loa nā hopena i nā hopena o nā haʻawina mua. Hōʻike mākou i ka papaʻaina hopena:
