The GNSSCP-SM12L1 from Linx Technologies is a Ceramic Patch Antenna that operates from 1567.24 to 1583.60 MHz and 1593.31 to 1608.68 MHz. It is designed for embedded GPS/GLONASS/GALILEO/BeiDou global navigation satellite system (GNSS) operation. This right-hand circular polarized antenna provides a gain of up to 2.9 dBi with an efficiency of up to 53% and has a VSWR of less than 7:1. It is a quarter-wave, omnidirectional antenna with an axial ratio of up to 19.7 dB and a 10-deg. elevation of 2 dBi.
The GNSSCP-SM12L1 provides a high gain and good radiation pattern performance that enables GNSS modules to provide location accuracy, rapid satellite signal reception, and quick time to first fix. It is available in a tape and reel package that measures 12 x 12 x 4 mm and can be reflow-solder mounted directly on to a printed circuit board for high-volume applications
