The MAT.03A Reference GPS and Cellular Embedded Antenna board combines the 2G/3G PA.25
Hexa-Band Cellular SMT Antenna and the ASGP.1575.25B.4.A.0 SMT 28dB Active GPS Patch
Antenna from Taoglas. It can be used as a reference board design or actual embedded antenna
for telematics applications such as fleet management, asset tracking, road pricing, and
security/surveillance. Best placement for this reference board in a device would be over the
existing mainboard and away from metal to allow for maximum radiated efficiency, and for the
GPS antenna to get a view towards the sky.
The board comes with one SMA(F) connector for each antenna feed on the bottom side for easy
connection via a cable assembly to a module or test equipment.
Cellular Antenna PA.25
This compact SMT ceramic high performance antenna achieves high efficiency on almost all
worldwide 2G and 3G bands, for applications such as GSM/GPRS/CDMA/HSPA. Transmission losses
are kept to absolute minimum resulting in much improved over the air (OTA) device performance
compared to similar efficiency cable and connector antenna solutions.
GPS Antenna ASGP.1575.25B.4.A.01
The patent pending revolutionary SMT GPS patch antenna allows for optimal GPS performance by
combining the ceramic patch, SAW, LNA, and feed pad in one integral sandwich package, mounted
on its own ground-plane. Having the SAW filter and LNA right after the feed reduces the chance
of noise entering the transmission line and boosts the GPS signal at the source before noise enters,
allowing for better signal to noise ratio.
It also frees up space on your board traditionally used for the filter and LNA.
The SAW is placed in front of the LNA, helping to prevent saturation due to nearby radio
transmitters, and the possibility of radiated spurious emissions through other radio systems.
Individual specifications on the antennas are available on the Taoglas website. Contact your
regional Taoglas office for support on integration of these antennas in your own device such as
gerber and layout review, and matching.
