Any idea on what this component is?
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.
