Hunhu hweceramic poda uye sintering process inobata zvakananga kuita kweiyo gps antenna.Iyo ceramic patch parizvino inoshandiswa pamusika inonyanya 25×25, 18×18, 15×15, uye 12×12.Iyo yakakura nzvimbo yeceramic patch, iyo yakakura iyo dielectric inogara, yakakwira iyo resonant frequency, uye zvirinani GPS antenna yekugamuchira maitiro.
Iyo sirivheri layer pamusoro peiyo ceramic antenna inogona kukanganisa resonant frequency yeantenna.Iyo yakanakira GPS ceramic chip frequency ndeye 1575.42MHz chaiyo, asi iyo antenna frequency inokanganiswa zviri nyore neyakapoteredzwa nharaunda, kunyanya kana yakaunganidzwa mumushini wese, iyo sirivheri yepamusoro yekupfeka inofanira kugadziriswa.Iyo frequency yeGPS navigation antenna inogona kugadziridzwa kuchengetedza chimiro cheGPS navigation antenna pa1575.42MHz.Naizvozvo, iyo GPS yakazara muchina inogadzira inofanirwa kushandirapamwe nemugadziri we antenna kana uchitenga antenna, uye nekupa yakazara muchina sampuro yekuyedza.
Iyo yekudyisa poindi inokanganisa kuita kweiyo gps antenna
Iyo ceramic antenna inounganidza iyo resonant chiratidzo kuburikidza nenzvimbo yekudyisa uye inoitumira kumucheto kumashure.Nekuda kwechinhu cheantenna impedance yekufananidza, iyo feed poindi kazhinji haisi pakati peiyo antenna, asi yakagadziridzwa zvishoma munzira yeXY.Iyi impedance yekufananidza nzira iri nyore uye haiwedzere Mutengo, inofamba chete munzira yeaxis imwe inonzi antenna imwe-yakarerekera, uye inofamba mumatemo ese ari maviri inonzi antenna yakapetwa kaviri.
Kusimudzira dunhu kunokanganisa kuita kwegps antenna
Chimiro uye nzvimbo yePCB inotakura ceramic antenna, nekuda kwechimiro cheGPS rebound, kana kumashure kuri 7cm x 7cm ivhu risina kukanganiswa, kuita kwechigamba antenna kunogona kukwidziridzwa.Kunyangwe iyo inorambidzwa nechitarisiko uye chimiro, edza kuichengeta zvakaringana Nzvimbo uye chimiro cheamplifier yunifomu.Kusarudzwa kwekuwana kweiyo amplifier circuit kunofanirwa kuenderana nekuwana kweiyo kumashure-yekupedzisira LNA.Iyo GSC 3F yeSirf inoda kuti kuwaniswa kwese kusati kwaiswa chiratidzo hakufanire kudarika 29dB, zvikasadaro iyo GPS yekufambisa antenna siginecha ichave yakawandisa uye yekuzvifarira.Iyo GPS antenna ine mana akakosha paramita: Gain, Standing Wave (VSWR), Noise Figure, uye Axial Ratio, pakati peiyo Axial Ratio inonyanya kusimbiswa, inova chiyero chekuwana chiratidzo chemuchina wese munzira dzakasiyana.chiratidzo chakakosha chemutsauko.Sezvo ma satellite achigoverwa zvisina tsarukano mudenga rehemispherical, zvakakosha kuve nechokwadi chekuti ma antenna ane manzwiro akafanana mumativi ese.Iyo axial ratio inokanganiswa nekuita kweGPS antenna, kutaridzika uye chimiro, dunhu remukati remuchina wese, uye EMI.
