Piezoelectric Ceramic Antenna for GPS

◉ PRODUCT SPECIFICATION

GPS Ceramic Antenna Specification

GPS is through the satellite signal to receive satellite positioning or navigation of the terminal and receive the signal must use the antenna. GPS satellite signals are divided into L1 and L2, the frequency of 1575.42MHz and 1228MHz, repectively, where L1 for the upgrade of civilian signal, the signal is circular polarization, the signal strength of -166dB or so, are relative weak signal. These features determine the preparation of a dedicated antenna for the reception of GPS signals.
