GPS A10137 Antenna Features:

GPS antenna designed for embedded applications
Balanced antenna technology
High efficiency
Good resistance to de-tuning
Designed for easy integration onto PCB
Low height, small footprint, light weight

Uses matching circuit and cut-out area for optimising efficiency. The antenna has balanced antenna characteristics. The minimum populated ground plane size is 20 x 30 mm. The antenna has RHCP characteristics suitable for reception of GPS signals.
It should be noted that the radiation patterns change with the size of the ground plane as described for the two reference boards indicated in the radiation patterns.
