COB-002

A product supports up to four systems antennas Special techniques are utilizedthat allowed the antenna to be 30% more efficient. Generally, 3G 4G antennas use chips or planar antennas, causing polarization directions to change, causing reception attenuation, We use stereo antennas to solve such problems. Generally, WIFI antennas use PIFA antennas. Since this signal is easily reflected by objects, causing polarization changes and receiving attenuation, we use circularly polarized antennas to solve such problems. Generally, GNSS antennas are susceptible to interference, resulting in reduced positioning accuracy. We use multi order filters to provide maximum 70dB isolation.
