Loaʻa i ka antenna dielectric nā kikoʻī maikaʻi loa me ke alapine waena o 1575.42MHz ±3 MHz e hōʻoia i ka hoʻokipa hōʻailona maikaʻi loa.ʻO ka VSWR ka 1.5: 1 a ʻo ka bandwidth ʻo ± 5 MHz, e hōʻoia ana i kahi pilina paʻa a maikaʻi me nā satelite GPS.Hoʻonui ka 50-ohm impedance i ka hoʻouna ʻana i ka hōʻailona.
Hoʻokumu ʻia ka antenna ma kahi mokulele honua 7x7cm a loaʻa ka loaʻa kiʻekiʻe ma mua o 3dBic.Hāʻawi ia i ka uhi waiwai maikaʻi loa, e hōʻoia ana i ka loaʻa haʻahaʻa o -4dBic ma nā kihi -90 ° a me +90 °, e uhi ana ma mua o 75% o ka nui o ka hāmeʻa.ʻO ka polarization ka polarization circular lima ʻākau (RHCP), ka mea e hoʻopaʻa i ka hoʻokipa hōʻailona mai nā satelite ma nā ʻaoʻao āpau.
Hoʻopiha ka LNA / kānana i ka antenna dielectric e hoʻomaikaʻi hou i ka hana.Me ka 28dB o ka loaʻa (me ka ʻole o ke kaula) a me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa 1.5dB, hoʻonui ia i nā hōʻailona GPS nāwaliwali a hōʻemi i ka hoʻopili ʻana i ka walaʻau, a laila e hoʻonui ai i ka mālamalama a me ka pololei.
Hāʻawi pū ka LNA / kānana i nā kānana kiʻekiʻe e hōʻemi i ke keakea o waho.Hāʻawi ia i ka liʻiliʻi o 7dB o ka attenuation ma f0+/-20MHz, ka liʻiliʻi o 20dB ma f0+/-50MHz, a me kahi 30dB o ka attenuation ma f0+/-100MHz.Hōʻoia kēia i kahi hōʻailona GPS maikaʻi a maikaʻi hoʻi, ʻoiai ma nā wahi ākea a walaʻau.
ʻO ka VSWR o ka LNA / kānana ʻoi aku ka liʻiliʻi ma mua o 2.0, e hōʻoiaʻiʻo ana i ka poho haʻahaʻa haʻahaʻa e hoʻonui i ka pono o ka hoʻouna ʻana i ka hōʻailona a hōʻemi i ka attenuation hōʻailona.
