Electronic – Any idea on what this component is

gpsidentificationRFsurface-mount

It's an 0402 sized component. Measures about 50 milliohms out of circuit. I also measured it with a cheap LCR meter and it shows -47nH. Capacitance measures 350mF. So I'm pretty sure it's a jumper. It's weird that it's on an antenna GPS feed line coming in from the middle right.

It looks like it's shorting the signal to ground. The component is half green half black and there are a few others of these on the circuit.

If it is a jumper why is it shorting the signal to ground?

50 mOhm resistance, 47nH inductance? Its probably an inductor. Murata make some thick film inductors in a green package with a black stripe. Its probably one of these: http://psearch.en.murata.com/inductor/product/LQG15HS10NJ02%23.pdf

Assuming the pin is the antenna then having an inductor feed into another inductor down to ground is a common circuit topology.
