ʻO kahi antena spiral planar he antenna i hoʻohana ʻia no ka hoʻouna ʻana a me ka loaʻa ʻana o nā hōʻailona electromagnetic polarized rotating i ka lewa, me nā ʻano a me nā noi.

ʻano ʻano

1. Ke ʻano polarization: ʻO ka antenna spiral planar he ʻano polarization lima hema a i ʻole ke ʻano polarization lima ʻākau.
2. Hoʻohālikelike impedance: He maikaʻi ka hana hoʻohālikelike impedance planar.
3. ʻO ke kuhikuhi ʻana o ka radiation: He maikaʻi ka hana antenna, me ka ʻaoʻao kiʻekiʻe o ka radiation ma ka ʻaoʻao maʻamau ma nā ʻaoʻao ʻelua o ka mokulele a me ka hoʻomālamalama ʻana i nā nalu circularly polarized.
4. Nā hiʻohiʻona pili ʻole i ka alapine: e like me nā antenna spiral equiangular, ʻo kona ʻano i hoʻoholo ʻia e ke kihi a ʻaʻole i komo ka lōʻihi laina, ʻaʻole pili ko lākou mau hiʻohiʻona e nā loli alapine, a loaʻa iā lākou kahi ʻāpana alapine ākea loa.

Palapala noi

1. ʻO ka hoʻomaʻamaʻa ʻana: Ma muli o ke ʻano polarization lima hema a lima ʻākau paha a me ka hana hoʻokele radiation maikaʻi, hiki i ka antenna horn ke loaʻa pololei nā hōʻailona electromagnetic i nā kuhikuhi kikoʻī a me nā polarizations no ka ʻike ʻana i ka orientation a me nā kumu hōʻailona.
2. Kūkākūkā Satellite: Hiki ke hoʻohana ʻia ka antenna horn RF ma ke ʻano he kumu hānai no nā satelite reflector, e hānai pono ana i nā hōʻailona ukali nāwaliwali i loaʻa i nā mea e loaʻa ai.
3. Nā kahua ʻē aʻe: Loaʻa i nā antenna puʻupuʻu Microwave nā noi i nā ʻōnaehana kamaʻilio ultra wideband, radar pūʻali, biotechnology, a me nā kahua ʻē aʻe, e like me ka pale ʻana i ka hoʻopili ʻana ma waena o ke kamaʻilio ultra wideband a me nā ʻōnaehana kamaʻilio narrowband.

Kaʻaleʻaleʻahoʻolako i nā antenna spiral planar e uhi i ke alapine a hiki i 40GHz. Hāʻawi mākou i nā antenna horn maʻamau o ka loaʻa 5dB, a me nā antenna horn polarized pālua e like me nā koi o nā mea kūʻai aku.
