Note for non magnetic surfaces.
Gps antenna metal sheet or not.
Antenna exceeds about 10 cm.
If there is no flat metal surface to mount the antenna you can create a ground plane by putting a 12 22cm diameter metal sheet directly below the antenna about 1 2 the signals wavelength which gives 1 4 wavelength per side.
Care should be taken that the gain of the lna inside the antenna does not lead to an overload condition at the receiver.
Some fancy antennas do not require that you add a ground plane.

The top metal frame was fed in a corner on the frame s longer edge with two shorting portions short circuited to the system ground.
Pieces of metal close to and above an antenna will badly disrupt the gps signal.
By carefully positioning the two shorting for the top metal frame the proposed loop antenna can provide the global positioning system gps operation at 1575mhz for smartwatch applications.
