New Products for 2022 GPS Antenna Use for Car Navigation

1.OverviewThe function of the GPS receiving antenna is to convert the electromagnetic wave energy of the radio signal from the satellite into the power supply that the receiver electronic device can ingest and apply. The GPS receiving antenna adopts the design of right-handed circular polarization, and is mainly used for receiving the L1 band of GPS satellites. The antenna has the characteristics of high gain, low standing wave ratio and strong receiving ability, etc. It converts the electromagnetic wave energy of the radio signal from the satellite into a power source that can be ingested and applied by the electronic device of the receiver. The GPS antenna is composed of a ceramic antenna body and an active amplifier. It is encapsulated in a plastic shell and has the characteristics of waterproof. The product is small in size and 3M glue is attached to the bottom of the antenna, which is easy to install and use.2.Antenna technical parametersDesign SpecificationsTypicalAntenna FormActive external antennaWorking Frequency1575.42±3MHzGain3.0dBiAntenna efficiency45%VSWR≤2.0 PloriaztionRC Pol Axial Ratio≤3.0Impedance50ΩInterfaceSMA Male/RG174(white Flame retardant)10mOveral dimensions48.5x37x19mmWeight206.2gOperatin Temp-40ºC~80ºCStoring Temp-40ºC~80ºC3.Amplifier characteristicNOItemSpecifications1Frequency range1575.42MHz2Amplifier gain28±3 dBi3 V.S.W.R≤2.04Noise factor
