I-antenna ye-dielectric inezincazelo ezinhle kakhulu ezinemvamisa yesikhungo engu-1575.42MHz ± 3 MHz ukuqinisekisa ukwamukelwa kwesignali okuphelele.I-VSWR ingu-1.5:1 kanti umkhawulokudonsa ungu-±5 MHz, oqinisekisa ukuxhumana okuzinzile nokusebenza kahle namasathelayithi e-GPS.I-impedance engu-50-ohm iphinde ithuthukise ukudluliswa kwesignali.
I-antenna isuselwe endizeni ephansi engu-7x7cm futhi inenzuzo ephezulu engaphezu kuka-3dBic.Ihlinzeka ngekhava yenzuzo enhle kakhulu, iqinisekisa ukuzuza okuncane okungu--4dBic kuma-engeli angu--90° kanye no-+90°, okumboza ngaphezu kuka-75% wevolumu yedivayisi.I-polarization i-circular polarization (RHCP) yesandla sokudla, eyenza ukwamukela isignali kusuka kumasathelayithi kuzo zonke izinhlangothi.
I-LNA/isihlungi sihambisana ne-antenna ye-dielectric ukuthuthukisa ukusebenza kahle.Ngenzuzo engu-28dB (ngaphandle kwekhebula) kanye nesibalo esiphansi somsindo ongu-1.5dB, ikhulisa amasignali e-GPS abuthaka futhi inciphise ukuphazamiseka komsindo, ngaleyo ndlela ithuthukise ukucaca kwesignali nokunemba.
I-LNA/isihlungi futhi sihlanganisa izihlungi zekhwalithi ephezulu ukuze kuncishiswe ukuphazamiseka okungaphandle kwebhendi.Inikeza ubuncane obungu-7dB bokuncishwa amandla ku-f0+/-20MHz, ubuncane obungu-20dB ku-f0+/-50MHz, kanye no-30dB ohlaba umxhwele wokuthokomalisa ku-f0+/-100MHz.Lokhu kuqinisekisa isignali ye-GPS ecacile nesezingeni eliphezulu, ngisho nasezindaweni eziminyene futhi ezinomsindo.
I-VSWR ye-LNA/isihlungi ingaphansi kuka-2.0, okuqinisekisa ukulahlekelwa okuphansi kokubuyisela ukuze kukhuliswe ukusebenza kahle kokudluliswa kwesignali kanye nokunciphisa ukuncishiswa kwesignali.
