Understanding SparkFun's Transceiver Breakout BoardEAGLE Schematics

[Anonymous]

Hello, 

I have been looking at the eagle schematics of SparkFun's Transceiver Breakout board (nRF24L01+ RP-SMA) and have a few questions that someone with more PCB design experience may be able to answer. The Eagle files are available under the document tab on the product page. My question involves the board files and why the board does not connect all of the ground traces. Below is a screenshot of what I mean:

Interesting to me was when I deleted the ground wires from the schematic and redrew them the board updated to look like this (I hid some layers so the vias are no longer visible).

 Here the board now has lines all over where traces were not drawn. Why is that the case? Why would you not want to connect the ground pads? Any insight would be appreciated!

From looking at the actual product image it looks like those pads are connected to a polygon in eagle. open the original file and hit ratsnest and see if it draws in the polygon (without doing any edits) . I think i can see the dotted outline of a polygon in your first image. So they are connected, just with a polygon fill instead of a routed trace. Go to the sparkfun link you posted and look at the image of teh board, you can see those pads are connected to a large copper pour.
