RM-PSA056-3 ʻĀkau-lima Circularly Polarized Planar Spiral Antenna no nā noi 0.5–6 GHz

Pono pinepine nā ʻōnaehana RF hou e hana ma nā ʻāpana alapine he nui me ka mālama ʻana i ka hana polarization paʻa i nā wahi hoʻonohonoho e loli nei. RF MISO'sRM-PSA056-3antenna wili pālahalahaua hoʻolālā ʻia e hoʻokō i kēia mau koi me ka uhi wideband mai0.5 a i 6 GHza me ka polarization pōʻai ʻākau.

Ma kahi o ka hilinaʻi ʻana i ka hoʻonohonoho pololei ma waena o ʻelua mau antennas polarized linearly, kōkua ka polarization circular i ka mālama ʻana i ka loaʻa ʻana o ka hōʻailona ke loli ke kuhikuhi o nā kahua hoʻouna a me ka loaʻa. ʻO kēia ka mea e pono ai ka RM-PSA056-3 i nā ʻōnaehana e pili ana i nā kahua e neʻe ana, ka hoʻololi ʻana i nā kuhikuhi hōʻailona, ​​​​nā wahi multipath, a i ʻole ka mana palena ma luna o ka hoʻonohonoho antenna.

Hāʻawi ka antenna3 dBi loaʻa maʻamau, heʻO ka VSWR maʻamau o 1.5:1, a me kahi2 dB lakio axial maʻamau. I ka hui pū ʻana, kākoʻo kēia mau ʻano i ka hoʻoili hōʻailona broadband kūpono a me ka polarization pōʻai ʻākau paʻa ma waena o kāna pae hana i manaʻo ʻia. ʻO ka ʻikepili VSWR i hoʻohālikelike ʻia, ka loaʻa, ka axial-ratio, a me ke ʻano radiation i loko o ka kikoʻī huahana e hāʻawi i nā ʻenekinia i kahi ʻike maopopo o ke ʻano antenna ma nā alapine like ʻole mai ka ʻaoʻao haʻahaʻa o ke kāʻei a hiki i ka 6 GHz.

Hoʻohui kona ʻano hoʻolālā planar spiral i ka uhi alapine ākea me kahi pā cylindrical liʻiliʻi. Ana ma kahi oØ160 × 79.4 mma me ke kaupaona ʻana1.128 kg, hiki ke hoʻohui ʻia ka antenna i loko o nā kahua RF e pili ana i ka lewa me ka ʻole o ka koi ʻana i ka ʻaoʻao hoʻonui ʻia o nā ʻano antenna kuʻuna he nui.

No ka hoʻolaha pono ʻana, ua kūkulu ʻia ka RM-PSA056-3 me ke kino alumini, kahi ʻano pena ʻeleʻele, a me kahi uhi antenna pale. Hāʻawi kona kūkulu wai ʻole i ka pale hou aku no nā ʻōnaehana kahua a me nā hoʻonohonoho i kau ʻia ma ke kaʻa kahi e hiki ai i ka antenna ke hōʻike ʻia i nā kūlana kaiapuni e loli nei. HeMea hoʻohui SMA-KHD3hāʻawi i kahi pilina maʻalahi no ka pili ʻana i nā kaula RF, nā mea loaʻa, nā mea hoʻoili, a me nā lako ana.

ʻO kaRM-PSA056-3he kūpono ia no nā ʻano hana wideband like ʻole, e like me:

• Hoʻāʻo EMC a me RF
• Ka nānā ʻana a me ka nānā ʻana i nā hōʻailona
• Nā ʻōnaehana ʻimi kuhikuhi
• Nā lako hana ʻike mamao
• Nā kahua kaʻa i kau ʻia ma luna
• Nā ʻōnaehana kamaʻilio a me ke ana ʻana o ka broadband

No nā ʻenekinia e hoʻomohala ana i nā kahua RF wideband compact, ʻo ka hana antenna hoʻokahi wale nō ʻāpana o ka pilikia hoʻolālā. ʻO ka hoʻohui ʻana o ka mīkini, ka palekana o ke kaiapuni, ke kūpaʻa polarization, a me ka hoʻohālikelike ʻana o ka mea hoʻohui he mea nui like. Hoʻohui ka RM-PSA056-3 i kēia mau koi i loko o kahi hopena antenna kūpono i hoʻolālā ʻia no ka loiloi hale hana, ka hoʻohui ʻana o ka ʻōnaehana, a me ka hoʻolaha ʻana i ke kahua.

Me kānaKa laulā o 0.5–6 GHz, polarization pōʻai ʻākau, VSWR maʻamau haʻahaʻa, pā paʻa, a me ka hoʻolālā pale wai, kaAntenna wili planar polarized poepoe ʻākau RM-PSA056-3hāʻawi i kahi koho maʻalahi no nā noi RF ʻoihana, kamaʻilio, nānā ʻana, a me nā noi ʻike mamao.
