5ghz omni antenna
1.1 Wehewehena o ka Base Station Antenna ʻO ka antenna base station he transceiver e hoʻohuli i nā nalu alakaʻi e hoʻolaha ana ma ka laina a me nā hawewe electromagnetic i hoʻomālamalama ʻia.Kūkulu ʻia ia ma ke kahua kahua.ʻO kāna hana ka lawe ʻana i nā hōʻailona hawewe electromagnetic a loaʻa paha nā hōʻailona.1.2 Hoʻokaʻawale ʻana i nā Antenna Base Station Ua hoʻokaʻawale ʻia nā antenna omnidirectional a me nā antenna kuhikuhi e like me ke kuhikuhi, a hiki ke hoʻokaʻawale ʻia i nā antenna hoʻokahi-polarized a me nā antenna polarized ʻelua e like me nā hiʻohiʻona polarization (ʻo ka polarization o ka antenna e pili ana i ke kuhikuhi o ka ikaika kahua uila i hoʻokumu ʻia i ka wā e hoʻomālamalama ai ka antenna. I ka ikaika o ke kahua uila Ke kū pololei ke kuhikuhi i ka honua, ua kapa ʻia ka nalu lekiō i ka nalu polarized vertical;i ka wā e like ai ka ikaika o ke kahua uila me ka honua, ua kapa ʻia ka hawewe lekiō. Hoʻopili ʻia nā antenna pālua-polarized ma nā ʻaoʻao ʻelua a me ke kū pololei.A ʻo nā antenna polarized hoʻokahi wale nō ka pae a i ʻole ke kū pololei).
2.1 Kūlana a me ke ʻano o ka Market Station Antenna Market I kēia manawa, ʻo ka nui o nā kahua kahua 4G ma Kina ma kahi o 3.7 miliona.E like me nā pono kalepa maoli a me nā ʻano loea, ʻo ka helu o nā kahua kahua 5G e pili ana i ka 1.5-2 mau manawa i ko nā kahua kahua 4G.ʻO ka helu o nā kahua kahua 5G ma Kina e manaʻo ʻia e hōʻea i ka 5-7 miliona, a ua manaʻo ʻia he 20-40 miliona mau antenna base station e pono ai i ka wā 5G.Wahi a ka hōʻike o ka Academia Sinica, ʻo ka nui o ka mākeke o nā antenna base station ma koʻu ʻāina e hiki i 43 biliona yuan ma 2021 a me 55.4 biliona yuan ma 2026, me kahi CAGR o 5.2% mai 2021 a i 2026. Ma muli o ka loli ʻana o nā kaila antenna base station a me ka pōkole holoʻokoʻa holoʻokoʻa o ka manawa 4G, ua piʻi iki ka nui o ka mākeke antenna i ka wā 4G mua ma 2014. Ma muli o ka hoʻomohala ikaika ʻana o 5G, manaʻo ʻia e piʻi ka nui o ka ulu ʻana o ka mākeke.Manaʻo ʻia e piʻi ka nui o ka mākeke i ka 78.74 biliona yuan ma 2023, me ka nui o ka ulu ʻana o ka makahiki he 54.4%.
3.1 ʻO ka hiki ʻana mai o ka wā 5G ʻO ka holomua wikiwiki o ka hoʻolaha ʻana o 5G kekahi o nā mea koʻikoʻi e hāpai i ka hoʻomohala ʻana o ka ʻoihana antenna base station.Hoʻopili pololei ka maikaʻi o ka antenna base station i ka ʻike mea hoʻohana, a ʻo ka hoʻolaha pāʻoihana o 5G e hāʻawi pololei i ka hoʻonui a me ka hoʻomohala ʻana i ka ʻoihana antenna base station.I ka hopena o 2021, ua kūkulu ʻia ka huina o 1.425 miliona 5G base station a wehe ʻia ma koʻu ʻāina, a ʻo ka huina o nā kahua kahua 5G ma koʻu ʻāina ʻoi aku ka nui ma mua o 60% o ka huina o ka honua.Pono no ka helu o nā antenna base station: ʻO ka attenuation o ka mana antenna e pili pono ana i ke alapine o ka hōʻailona. ʻOi aku ka kiʻekiʻe o ka mana antenna 5G ma mua o ka 4G.Ma lalo o nā kūlana like, ʻo ka uhi o nā hōʻailona 5G he hapaha wale nō o ka 4G.No ka hoʻokō ʻana i ka ʻāpana uhi like o nā hōʻailona 4G, Pono ka hoʻolālā kahua kahua nui e hoʻokō i ka ʻO ka ikaika hōʻailona i loko o ka uhi wahi, no laila e hoʻonui nui ʻia ka pono o nā antenna base station.
4.1 Nui MIMO ʻenehana MIMO ʻenehana ka ʻenehana kumu o ke kamaʻilio 4G.Ma ka hoʻokomo ʻana i nā mea hoʻouna a me ka loaʻa ʻana o nā antenna he nui i nā lako lako, hiki ke hoʻouna a loaʻa nā hōʻailona he nui ma waena o nā antenna he nui.Ma lalo o ke kūlana o nā kumu waiwai spectrum palena a me ka mana hoʻouna, E hoʻomaikaʻi i ka maikaʻi o ka hoʻouna ʻana i ka hōʻailona a hoʻonui i nā ala kamaʻilio. ʻO ka ʻenehana MIMO nui nui o MIMO, e pili ana i ke kākoʻo kumu mua o MIMO i nā awa antenna 8 wale nō, hoʻomaikaʻi i ka uhi pūnaewele a me ka paʻa ʻana ma o ka hoʻohui ʻana i nā antennas he nui e hana i nā kumuwaiwai spatial dimension a hoʻonui i ka hiki o ka ʻōnaehana. Hāʻawi ka ʻenehana MIMO nui i nā koi kiʻekiʻe ma nā antenna base station.Pono ka ʻenehana MIMO nui i ka hoʻokomo ʻana i kahi helu nui o nā antenna i hoʻokaʻawale maikaʻi ʻia i loko o kahi wahi lako i kaupalena ʻia e hōʻoia i ka loaʻa a me ka pololei e pono ai no ka beamforming. Pono kēia ʻenehana i ka miniaturized ka antenna, me ke kaʻawale kiʻekiʻe a me nā ʻano ʻē aʻe.I kēia manawa, hoʻohana ka ʻenehana antenna Massive MIMO i kahi hopena 64-channel.ʻenehana 4.2 mmWave Ma muli o nā hiʻohiʻona o ka mamao hoʻolaha pōkole a me ka attenuation koʻikoʻi o nā nalu 5G millimeters, Hiki ke hōʻoia i ka maikaʻi o ka hoʻouna ʻana, a ʻo ka nui o nā antenna o kahi kahua kahua hoʻokahi e hiki i ka ʻumi a i ʻole haneli.ʻAʻole pili ka antenna passive kuʻuna no ka mea ʻoi aku ka nui o ka nalowale o ka hōʻailona a ʻaʻole hiki ke hoʻouna ʻia ka hōʻailona me ka maʻalahi.
