ANT0104 Ultra Wideband Omnidirectional Antenna
| Alakai-mw | Introduction to Ultra Wideband Omnidirectional Antenna |
Ke hoʻolauna nei i alakaʻi ʻenehana microwave., (leader-mw) hou ultra-wideband omnidirectional antenna ANT0104. Hoʻolālā ʻia kēia antenna ikaika e hana ma luna o kahi ākea ākea mai 20MHz a 3000MHz, kūpono ia no nā ʻano noi like ʻole me nā kamaʻilio kelepona, nā ʻōnaehana radar a me nā mea hou aku.
ʻOi aku ka nui o ka loaʻa ʻana o kēia antenna ma mua o 0dB, a ʻo ka hoʻololi ʻana o ka pōʻai kiʻekiʻe he ± 1.5dB, e hōʻoiaʻiʻo ana i ka hoʻouna ʻana i nā hōʻailona hilinaʻi. Hoʻonui hou ʻia kāna hana e kahi ± 1.0dB hoʻohālikelike hoʻoheheʻe ʻana, e hāʻawi ana i ka uhi maikaʻi loa ma nā ʻaoʻao āpau.
Loaʻa i ka ANT0104 nā hiʻohiʻona polarization kūwaho, kūpono ia no nā noi kahi i makemake ʻia ai ka hoʻouna kū pololei. Eia kekahi, ʻo VSWR ≤2.5: 1 a me 50 ohm impedance o ka antenna e hāʻawi i ka hoʻohālikelike impedance maikaʻi loa a me ka nalowale o ka hōʻailona liʻiliʻi.
ʻO kāna hoʻolālā paʻa a paʻakikī hoʻi e kūpono ia no ka hoʻohana ʻana i loko a me waho, a ʻo kāna hana omnidirectional e hiki ai ke hoʻohui pono i nā wahi āpau.
Inā makemake ʻoe e hoʻonui i ka ikaika hōʻailona o kāu pūnaewele uea, hoʻonui i ka hana o kāu ʻōnaehana radar, a i ʻole makemake e hōʻoia i nā kamaʻilio hilinaʻi ma kahi ākea ākea, ʻo ka ANT0104 Ultra Wideband Omnidirectional Antenna ka hopena kūpono.

No ke ana pono o ka antenna directivity coefficient D, wehewehe makou ia mai ka nui o ka antenna radiation beam range.
ʻO Directivity D ka lākiō o ka mana hoʻomāliʻi nui loa P(θ,φ) Max i kona kumu waiwai P(θ,φ)av ma kahi pōʻai ma ka ʻāpana mamao loa, a he ratio dimenonless ʻoi aku ka nui a i ʻole like me 1 Penei ka helu helu.
Eia hou, hiki ke helu ʻia ka kuhikuhi D e ke ʻano hoʻohālikelike:
D = 4 PI / Ω _A
I ka hoʻomaʻamaʻa, hoʻohana pinepine ʻia ka helu logarithmic o D e hōʻike i ka loaʻa kuhikuhi o kahi antenna:
D = 10 log d
Hiki ke unuhi ʻia ka kuhikuhi kuhikuhi D ma luna aʻe ma ke ʻano he lākiō o ka laulā pōʻai (4π rad²) antenna beam range ω _A. No ka laʻana, inā hoʻomālamalama wale ka antenna i ka ʻāpana hemispherical luna a ʻo kona laulā kaola ʻo ω _A=2π rad², a laila ʻo kona kuhikuhi ʻana:
Inā lawe ʻia ka logarithm o nā ʻaoʻao ʻelua o ka hoʻohālikelike i luna, hiki ke loaʻa ka loaʻa kuhikuhi o ka antenna e pili ana i ka isotropy. Pono e hoʻomaopopo ʻia hiki i kēia loaʻa ke hōʻike wale i ka radiation pattern directional o ka antenna, i ka ʻāpana o dBi, no ka mea ʻaʻole i manaʻo ʻia ka maikaʻi o ka lawe ʻana i ka waiwai kūpono. Penei ka helu ana.

ʻO nā ʻāpana antenna loaʻa ʻo dBi a me dBd, kahi:
DBi: ʻo ia ka loaʻa i loaʻa mai i ka radiation antenna e pili ana i ke kumu kiko, no ka mea, aia ke kumu kiko ω _A=4π a ʻo ka loaʻa kuhikuhi he 0dB;
DBd: ʻo ia ka loaʻa o ka radiation antenna e pili ana i ka hapalua hawewe dipole antenna;
ʻO ke kumu hoʻololi ma waena o dBi a me dBd:
