Currently, most GPS antennas are right-handed polarized ceramic media consisting of ceramic antennas, low-noise signal modules, cables, and connectors. Ceramic antenna, also known as passive antenna, dielectric antenna and patch, is the core technology of GPS Antenna. The reception ability of GPS antenna depends largely on its ceramic components. Low noise signal module, also known as LNA, is the part that amplifies and filters the signal. The selection of components is also very important, otherwise it will increase the reflection loss of GPS signal, resulting in excessive noise. Cable selection should also be based on reducing reflection to ensure impedance matching Combo GPS Antenna,2 in1 GPS Antenna,3 In 1 GPS Antenna,GPS+WIFI Antenna,GPS +4G +Wifi antenna Yetnorson Antenna Co., Ltd. , https://www.yetnorson.com
The company expects to add 275 North Carolina jobs during 2009 to serve the expansion of LED manufacturing capacity and other staffing needs at its Durham, NC, facility. Cree anticipates creating an additional 300 jobs by the end of 2012.
