Antenna microstriphe ʻano microwave houantennae hoʻohana ana i nā ʻāpana conductive i paʻi ʻia ma kahi substrate dielectric e like me ka ʻāpana hoʻomālamalama antenna.Ua hoʻohana nui ʻia nā antenna Microstrip i nā ʻōnaehana kamaʻilio hou ma muli o ko lākou liʻiliʻi liʻiliʻi, ke kaumaha māmā, haʻahaʻa haʻahaʻa, a me ka maʻalahi hoʻohui.
Pehea ka hana ʻana o ka microstrip antenna
Hoʻokumu ʻia ke kumu hana o ka microstrip antenna i ka hoʻouna ʻana a me ka radiation o nā hawewe electromagnetic.ʻO ka mea maʻamau i loaʻa i kahi pā radiation, substrate dielectric a me ka pā lepo.Paʻi ʻia ka pā radiation ma ka ʻili 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 nui o ka microstrip antenna.He wahi metala lohi ia no ka hopu ʻana a me ka hoʻomālamalama ʻana i nā nalu electromagnetic.
2. Pākuʻi Dielectric: Hana ʻia ka substrate dielectric i nā mea haʻahaʻa haʻahaʻa, kiʻekiʻe-dielectric-constant, e like me polytetrafluoroethylene (PTFE) a i ʻole nā mea hana seramika.ʻO kāna hana ʻo ke kākoʻo ʻana i ka pā radiation a lawelawe ma ke ʻano he ʻano no ka hoʻolaha ʻana o ka hawewe electromagnetic.
3. Papa honua: ʻO ka pā honua he papa metala nui aʻe i loaʻa ma kēlā ʻaoʻao o ka substrate dielectric.Hoʻokumu ia i ka hoʻopili capacitive me ka pā radiation a hāʻawi i ka hoʻohele electromagnetic pono.
Ke hāʻawi ʻia ka hōʻailona microwave i loko o ka microstrip antenna, hana ia i kahi nalu kū ma waena o ka pā radiation a me ka papa honua, e hopena i ka radiation o nā hawewe 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.

ʻO ka ʻokoʻa ma waena o ka microstrip antenna a me ka patch antenna
ʻO Patch antenna kahi ʻano o ka microstrip antenna, akā aia kekahi mau ʻokoʻa i ka hoʻolālā a me nā loina hana ma waena o nā mea ʻelua:
1. Nā ʻokoʻa i kūkulu ʻia:
ʻO Microstrip antenna: ʻo ia ka mea maʻamau i kahi pā radiation, kahi substrate dielectric a me kahi pā lepo.Hoʻokuʻu ʻia ka pā ma ka substrate dielectric.
Patch Antenna: Hoʻopili pololei ʻia ka mea radiating o ka patch antenna i ka substrate dielectric, maʻamau me ka ʻole o kahi ʻano i hoʻokuʻu ʻia.
2. Keʻano hanai:
Antenna Microstrip: Hoʻopili pinepine ʻia ka hānai i ka pā radiating ma o nā probes a i ʻole nā laina microstrip.
Patch antenna: ʻOi aku ka ʻokoʻa o nā ʻano hana hānai, hiki ke ʻai i ka lihi, ka hānai slot a i ʻole ka hānai coplanar, etc.
3. ʻO ka pono o ka radiation:
ʻO Microstrip antenna: No ka mea aia kekahi ʻokoʻa ma waena o ka pā radiation a me ka papa honua, aia paha kekahi nui o ka nalowale o ka ea, e pili ana i ka pono radiation.
Patch antenna: Hoʻohui pū ʻia ka mea hoʻomālamalama o ka antenna patch me ka substrate dielectric, ka mea maʻamau i ʻoi aku ka maikaʻi o ka radiation.
4. Hana ʻana i ka bandwidth:
Microstrip antenna: ʻOi aku ka liʻiliʻi o ka bandwidth, a pono e hoʻonui ʻia ka bandwidth ma o ka hoʻolālā optimized.
Patch antenna: Hiki ke hoʻokō ʻia ka bandwidth ākea ma ka hoʻolālā ʻana i nā ʻano hana like ʻole, e like me ka hoʻohui ʻana i nā iwi ʻaoʻao radar a i ʻole ka hoʻohana ʻana i nā ʻōnaehana multi-layer.
5. Nā manawa noi:
ʻO Microstrip antenna: kūpono i nā noi i loaʻa nā koi koʻikoʻi i ke kiʻekiʻe kiʻekiʻe, e like me nā kamaʻilio satellite a me nā kamaʻilio kelepona.
Patch antennas: Ma muli o ko lākou ʻano like ʻole, hiki ke hoʻohana ʻia i kahi ākea ākea o nā noi, me ka radar, nā LAN uila, a me nā ʻōnaehana kamaʻilio pilikino.
I ka hopena
ʻO nā antenna Microstrip a me nā antenna patch ka mea maʻamau i hoʻohana ʻia i nā antenna microwave i nā ʻōnaehana kamaʻilio hou, a loaʻa iā lākou ko lākou mau hiʻohiʻona a me nā pono.ʻOi aku ka maikaʻi o nā antenna Microstrip i nā noi i hoʻopaʻa ʻia ma muli o ko lākou haʻahaʻa haʻahaʻa a me ka hoʻohui maʻalahi.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 hana kiʻekiʻe ma muli o ko lākou kiʻekiʻe radiation kiʻekiʻe a me ka hoʻolālā.
No ka ʻike hou aku e pili ana i nā antenna, e kipa:
