He pai rawa nga korero a te antenna dielectric me te auau pokapū o 1575.42MHz ±3 MHz kia pai ai te whiwhi tohu tohu.Ko te VSWR ko 1.5: 1 me te bandwidth ko ± 5 MHz, e whakarite ana i te hononga pumau me te pai ki nga peerangi GPS.Ko te 50-ohm impedance ka whakanui ake i te tuku tohu.
Ko te antenna kei runga i te rererangi whenua 7x7cm, he nui ake te whiwhinga o te 3dBic.E whakarato ana i te kapinga painga pai, me te whakarite i te whiwhinga iti o -4dBic i nga koki -90° me +90°, neke atu i te 75% o te rōrahi taputapu.Ko te polarization he polarization porohita ringa matau (RHCP), e arotau ana i te tango tohu mai i nga amiorangi i nga huarahi katoa.
Ka whakakiia e te LNA/tātari te antenna dielectric kia pai ake te mahi.Ma te 28dB o te whiwhi (kare he taura) me te iti o te haruru o te 1.5dB, ka whakanuia e ia nga tohu GPS ngoikore me te whakaiti i te haruru o te haruru, na reira ka whakanui ake i te marama me te tika o te tohu.
Kei te LNA/tātari hoki nga whiriwhiringa kounga teitei hei whakaiti i te pokanoa ki waho o te roopu.He iti rawa te 7dB o te whakaheke i te f0+/-20MHz, te iti rawa o te 20dB i te f0+/-50MHz, me te 30dB whakamīharo i te f0+/-100MHz.Ma tenei ka whakarite i te tohu tohu GPS maamaa me te kounga teitei, ahakoa i roto i nga taiao e kikii ana me te ngangau.
Ko te VSWR o te LNA/tātari he iti ake i te 2.0, e whakapumau ana i te iti o te hokinga mai ki te whakanui i te pai o te tuku tohu me te whakaiti i te whakahekenga tohu.
