E PILI I KĒIA MANAWA

ʻO ka antenna wili planar kahi antenna i hoʻohana ʻia no ka hoʻouna ʻana a me ka loaʻa ʻana o nā hōʻailona electromagnetic polarized e wili ana i ka lewa, me nā ʻano a me nā noi aʻe.

ʻAno

1. ʻAno polarization: Loaʻa i ka antenna wili planar kahi ʻano polarization lima hema a i ʻole kahi ʻano polarization lima ʻākau.
2. Hoʻohālikelike impedance: Loaʻa i ka antenna wili planar ka hana hoʻohālikelike impedance maikaʻi.
3. Kuhikuhi radiation: Loaʻa i ka antenna ka hana kuhikuhi radiation maikaʻi, me ke kuhikuhi radiation kiʻekiʻe loa ma ke kuhikuhi maʻamau ma nā ʻaoʻao ʻelua o ka mokulele a hoʻomālamalama i nā nalu polarized circularly.
4. Nā ʻano hilinaʻi ʻole i ke alapine (frequency): e like me nā antennas wili equiangular, nona ke ʻano i hoʻoholo ʻia e ke kihi a ʻaʻole hoʻokomo i ka lōʻihi linear, ʻaʻole i hoʻopilikia ʻia ko lākou ʻano e nā loli alapine, a he ākea loa ko lākou alapine.

Noi

1. Ke kuhikuhi ʻana i ka nānā ʻana: Ma muli o ke ʻano polarization hema a ʻākau paha a me ka hana kuhikuhi radiation maikaʻi, hiki i ka antenna pepeiaohao ke loaʻa pololei nā hōʻailona electromagnetic i nā kuhikuhi kikoʻī a me nā polarizations no ka nānā ʻana i ke kuhikuhi pahuhopu a me nā kumu hōʻailona.
2. Kamaʻilio ukali: Hiki ke hoʻohana ʻia ka antenna pepeiaohao RF ma ke ʻano he kumu hānai no nā ukali reflector, e hānai pono ana i nā hōʻailona ukali nāwaliwali i loaʻa i nā lako e loaʻa ana.
3. Nā kahua ʻē aʻe: Loaʻa i ka antenna pepeiaohao Microwave nā noi i nā ʻōnaehana kamaʻilio ultra wideband, radar koa, biotechnology, a me nā kahua ʻē aʻe, e like me ka pale ʻana i ka hoʻopilikia ma waena o ke kamaʻilio ultra wideband a me nā ʻōnaehana kamaʻilio narrowband.

QualwaveHoʻolako nā antennas wili planar i ka laulā alapine a hiki i ka 40GHz. Hāʻawi mākou i nā antennas pepeiaohao loaʻa maʻamau o ka loaʻa 4dB, 5dB, 7dB, a me nā antennas pepeiaohao polarized pālua i hoʻopilikino ʻia e like me nā koi o nā mea kūʻai aku.
