He aha ka Antenna Microstrip? ʻAno, Kumu Hana a me nā Noi

ʻIke Huahana a me ka ʻenehana

ʻO ka antenna microstrip he antenna planar i hana ʻia e kahi ʻāpana conductive radiating, kahi substrate dielectric, a me kahi mokulele honua. Hoʻopaʻa pinepine ʻia ka ʻāpana ma kekahi ʻaoʻao o ka substrate, ʻoiai ua kau ʻia ka mokulele honua ma ka ʻaoʻao ʻē aʻe. ʻO kēia ʻano hana e hana ai i ka antenna i lahilahi, māmā, a kūpono no ke kau ʻana ma nā kahua pālahalaha a ʻūlū iki paha.

I loko o ka ʻenekinia RF maoli, ua waiwai nui ʻia nā antenna microstrip no ka mea hiki ke hoʻohui ʻia me nā kaapuni microwave, nā phased arrays, nā radomes, a me nā hale ʻōnaehana compact. Hiki ke hoʻoponopono ʻia ko lākou mau ʻano radiation ma o ka patch geometry, ka mea substrate, ke ʻano hānai, ka hoʻonohonoho array, a me ka hoʻolālā mechanical.

ʻO ke ʻano kumu o kahi Antenna Microstrip

ʻEkolu mau papa nui o kahi antenna microstrip maʻamau. Hana ka ʻāpana metala luna ma ke ʻano he element radiation. Kākoʻo ka substrate dielectric i ka patch a hoʻopilikia i ka bandwidth, ka pono, a me ka nui. Kōkua ka mokulele honua lalo i ka wehewehe ʻana i ke ʻano radiation a hoʻokaʻawale i ka antenna mai ka ʻili kau.

Pāpili hoʻomālamalama	ʻO ka maʻamau he ʻāpana huinahā, poepoe, a i ʻole ke ʻano maʻamau no ke alapine (frequency) a me ka polarization e pono ai.
ʻO ka substrate dielectric	I koho ʻia e like me ka pohō RF, ka dielectric constant, ka mānoanoa, ka bandwidth, a me nā koi o ke kaiapuni.
Papahele honua	Hāʻawi i kahi mokulele kuhikuhi a kōkua i ka hana radiation paʻa.
ʻAno hānai	Hiki ke hoʻohana i kahi laina microstrip, coaxial probe, aperture coupling, a i ʻole proximity coupling ma muli o ka pahuhopu hoʻolālā.

Pehea e hana ai kahi Antenna Microstrip?

Ke hoʻokomo ʻia ka ikehu RF i loko o ka ʻāpana, hoʻokumu ʻia kahi kahua electromagnetic ma waena o ka ʻāpana a me ka mokulele honua. Loaʻa ka radiation ma kahi kokoke i nā kihi o ka ʻāpana, kahi e hoʻonui ai ke kahua fringing i ka hakahaka a puni.

Pili loa ke alapine hana i ka nui o ka patch, ka substrate dielectric constant, a me ka mānoanoa o ka substrate. No kahi patch rectangular, pili pinepine ka lōʻihi resonant i ka hapalua o ka wavelength alakaʻi i loko o ka substrate.

I nā hoʻolālā maoli, pono e hoʻomaikaʻi ʻia nā ana hope loa no ka mea hiki i ka hoʻouka dielectric, ke kūlana hānai, ka hale, nā mea radome, a me nā hale metala kokoke ke hoʻopilikia i ka hana i ana ʻia.

Nā ʻAno Hānai Maʻamau

ʻAno Hānai	Pōmaikaʻi Maʻamau	Ka Noʻonoʻo ʻenekinia
Ka Hānai Laina Microstrip	ʻO ke ʻano paʻi maʻalahi a me ka hoʻohui PCB maʻalahi.	Pono e hoʻomalu pono ʻia ka hoʻomehana ʻana o ka laina hānai a me ke kūlike ʻana.
Ka Hānai Probe Coaxial	Koho ʻana i kahi kiko hānai maʻalahi no ka hoʻohālikelike impedance.	Hiki i ka ʻākoakoa mechanical a me ka probe inductance ke hoʻopilikia i ka bandwidth.
Ka Hānai Hoʻopili ʻia me ka Aperture	Hoʻokaʻawale maikaʻi ma waena o ka pūnaewele hānai a me ka mea hoʻomālamalama.	ʻOi aku ka paʻakikī o ka hoʻonohonoho ʻana o nā papa he nui a me ka mana hana paʻa.
Ka Hānai Hoʻopili Kokoke	Hiki ke kōkua i ka hoʻomaikaʻi ʻana i ka bandwidth i nā hoʻolālā i koho ʻia.	Pono i ka hoʻonohonoho pono ʻana o ka papa a me ke koho ʻana i nā mea.

Nā Pōmaikaʻi a me nā Palena

Nā Pōmaikaʻi ʻAno haʻahaʻa a māmā hoʻi. Kūpono no nā ʻōnaehana RF a me nā ʻōnaehana microwave liʻiliʻi. Kūlike me nā kaapuni planar a me nā hoʻonohonoho array. Hiki ke kākoʻo i ka polarization linear a circular paha ma muli o ka hoʻolālā. ʻAno a me ka hoʻonohonoho maʻalahi no ka hoʻohui ʻana i hana ʻia.

Nā Palena ʻOi aku ka haiki o ka bandwidth ma mua o kekahi mau ʻano antenna pepeiaohao a i ʻole reflector. Hiki ke hoʻopili ʻia ka pono e ka pohō dielectric a me ka pohō conductor. ʻIke iki ka hana i ka mea substrate, ka mānoanoa, a me nā hale kokoke. Pono e noʻonoʻo ʻia nā kumu wela, kaiapuni, a me nā mea mechanical no nā noi koi.

Nā Hoʻohana Maʻamau

Ma muli o ko lākou ʻano planar a me ka maʻalahi o ka hoʻolālā, hoʻohana ʻia nā antenna microstrip ma nā kahua RF a me nā microwave kahi e nui ai ka hakahaka, ke kaumaha, a me ka hoʻohui ʻana.

Nā ʻōnaehana RadarNā wēlau mua radar liʻiliʻi, nā ʻāpana pae, a me nā kahua ʻike kuhikuhi.	Aerospace a me ka Pale KauaHoʻokomo haʻahaʻa kahi e koʻikoʻi ai ke kiʻekiʻe a me ke kaumaha mechanical.	Kamaʻilio Uea ʻoleNā loulou microwave, nā antennas terminal, a me nā modula kamaʻilio i hoʻohui ʻia.
Ana ʻana o ka AntennaNā keʻena hoʻokolohua RF no ka hoʻāʻo ʻana, hoʻohālikelike, a me ka loiloi pae ʻōnaehana.	Hoʻokele a me TelemetryNā hui i koho ʻia a me nā koi polarization.	Hoʻohui ʻōnaehanaKe kaulike nei i ka hana antenna me nā palena o ka pā a me ka paepae.

Nā Antennas Array Microstrip

Hiki ke hoʻohana wale ʻia kahi mea microstrip hoʻokahi, akā nui nā ʻōnaehana microwave e koi ana i ka loaʻa kiʻekiʻe, nā kukuna i hoʻohālikelike ʻia, a i ʻole ka hiki ke scan. I kēia mau hihia, hiki ke hoʻonohonoho ʻia nā mea patch he nui i loko o kahiantenna hoʻonohonoho microstrip.

Ma ka kaohi ʻana i ka element spacing, ka hānai ʻana i ka pūnaewele, ka amplitude, a me ka hoʻolaha ʻana o ka phase, hiki i nā ʻenekinia ke hoʻokō i nā beamwidth like ʻole, sidelobe, gain, a me nā pahuhopu polarization. Manaʻo pinepine ʻia nā antennas array Microstrip no ka radar, ka kamaʻilio ukali, ke ana uila, a me nā ʻōnaehana RF kuhikuhi compact.
