That is a GPS chip antenna. Itty-bitty! And we were just as surprised when it picked up just as many satellites as the larger ceramic antennas. The PDOP and VDOP (dilution of precision) of these chip antennas are greater than their ceramic siblings and the gain is not as great (to be expected), but heck, if you can get a lock with this little guy, who cares?
Note: This is just a GPS antenna and is not a complete GPS module. For a complete module, check out our GPS category.
