Antenna microstriphe ʻano microwave hou iaantennae hoʻohana ana i nā ʻāpana conductive i paʻi ʻia ma kahi substrate dielectric ma ke ʻano he ʻāpana antenna radiation. Ua hoʻohana nui ʻia nā antennas Microstrip i nā ʻōnaehana kamaʻilio hou ma muli o ko lākou liʻiliʻi, ke kaumaha māmā, ka ʻaoʻao haʻahaʻa, a me ka hoʻohui maʻalahi.
Pehea e hana ai ka antenna microstrip
ʻO ke kumu hana o ka antenna microstrip e pili ana i ka hoʻoili ʻana a me ka radiation o nā nalu electromagnetic. ʻO ka maʻamau, aia ia he ʻāpana radiation, substrate dielectric a me ka papa honua. Ua paʻi ʻia ka ʻāpana radiation ma luna o ka substrate dielectric, ʻoiai aia ka papa honua ma kēlā ʻaoʻao o ka substrate dielectric.
1. Pākuʻi radiation: ʻO ka pākuʻi radiation kahi ʻāpana koʻikoʻi o ka antenna microstrip. He ʻāpana metala lahilahi ia e kuleana no ka hopu ʻana a me ka hoʻopuehu ʻana i nā nalu electromagnetic.
2. Dielectric substrate: Hana pinepine ʻia ka dielectric substrate me nā mea pohō haʻahaʻa, kiʻekiʻe-dielectric-constant, e like me ka polytetrafluoroethylene (PTFE) a i ʻole nā mea seramika ʻē aʻe. ʻO kāna hana ke kākoʻo i ka ʻāpana radiation a lawelawe ma ke ʻano he medium no ka hoʻolaha ʻana o nā nalu electromagnetic.
3. Papa honua: ʻO ka papa honua kahi papa metala nui aʻe i loaʻa ma kēlā ʻaoʻao o ka substrate dielectric. Hoʻokumu ia i ka hoʻopili capacitive me ka ʻāpana radiation a hāʻawi i ka hoʻolaha kahua electromagnetic e pono ai.
Ke hoʻokomo ʻia ka hōʻailona microwave i loko o ka antenna microstrip, hana ia i kahi nalu kū ma waena o ka ʻāpana radiation a me ka papa honua, e hopena ana i ka radiation o nā nalu electromagnetic. Hiki ke hoʻoponopono ʻia ka pono o ka radiation a me ke ʻano o kahi antenna microstrip ma ka hoʻololi ʻana i ke ʻano a me ka nui o ka patch a me nā ʻano o ka substrate dielectric.
RFMISONā Manaʻo no ka Moʻo Antenna Microstrip:
RM-DAA-4471（4.4-7.5GHz）

RM-MA25527-22（25.5-27GHz）
RM-MA424435-22（4.25-4.35GHz）
ʻO ka ʻokoʻa ma waena o ka antenna microstrip a me ka antenna patch
ʻO ka antenna patch kahi ʻano o ka antenna microstrip, akā aia kekahi mau ʻokoʻa i ke ʻano a me ke kumu hana ma waena o nā mea ʻelua:
1. Nā ʻokoʻa kūkulu:
ʻO ka antenna microstrip: ʻo ka maʻamau he ʻāpana radiation, kahi substrate dielectric a me kahi papa honua. Hoʻokuʻu ʻia ka patch ma luna o ka substrate dielectric.
Antenna Patch: Hoʻopili pololei ʻia ka mea hoʻomālamalama o ka antenna patch i ka substrate dielectric, maʻamau me ka ʻole o kahi ʻano hoʻokuʻu maopopo.
2. ʻAno hānai:
ʻAntenna Microstrip: Hoʻopili pinepine ʻia ka hānai i ka ʻāpana radiating ma o nā probes a i ʻole nā laina microstrip.
Antenna Patch: ʻOi aku ka ʻokoʻa o nā ʻano hānai, hiki ke hānai ʻia ma ka lihi, ka hānai slot a i ʻole ka hānai coplanar, a pēlā aku.
3. Ka pono o ka hoʻolaha ʻana:
ʻO ka antenna Microstrip: Ma muli o kahi āpau ma waena o ka ʻāpana radiation a me ka papa honua, aia paha kekahi nui o ka nalowale o ka ea, kahi e hoʻopilikia ai i ka pono o ka radiation.
Antenna Patch: Hoʻohui pū ʻia ka mea hoʻomālamalama o ka antenna patch me ka substrate dielectric, kahi i loaʻa pinepine ka pono radiation kiʻekiʻe.
4. Hana bandwidth:
ʻO ka antenna Microstrip: He haiki ka bandwidth, a pono e hoʻonui ʻia ka bandwidth ma o ka hoʻolālā i hoʻomaikaʻi ʻia.
Antenna Patch: Hiki ke hoʻokō ʻia ka bandwidth ākea ma ka hoʻolālā ʻana i nā ʻano like ʻole, e like me ka hoʻohui ʻana i nā iwi radar a i ʻole ka hoʻohana ʻana i nā ʻano multi-layer.
5. Nā manawa noi:
Antenna Microstrip: kūpono no nā noi me nā koi koʻikoʻi ma ke kiʻekiʻe o ke ʻano, e like me ke kamaʻilio ukali a me nā kamaʻilio kelepona.
Nā antennas Patch: Ma muli o ko lākou ʻano like ʻole o ke ʻano, hiki ke hoʻohana ʻia i kahi ākea o nā noi, me ka radar, nā LAN uea ʻole, a me nā ʻōnaehana kamaʻilio pilikino.
I ka hopena
ʻO nā antenna Microstrip a me nā antenna patch he mau antenna microwave i hoʻohana pinepine ʻia i nā ʻōnaehana kamaʻilio hou, a he mau ʻano ponoʻī a me nā pono ko lākou. ʻOi aku ka maikaʻi o nā antenna Microstrip i nā noi i kaupalena ʻia i ka hakahaka ma muli o ko lākou ʻano haʻahaʻa a me ka maʻalahi o ka hoʻohui ʻana. ʻO nā antenna Patch, ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka maʻamau i nā noi e koi ana i ka bandwidth ākea a me ka pono kiʻekiʻe ma muli o ko lākou pono radiation kiʻekiʻe a me ka hiki ke hoʻolālā.
No ka ʻike hou aku e pili ana i nā antennas, e kipa i ka pūnaewele:
