Cannot get antenna polygon to fill

I followed the advice of couple of posters who suggested that a way to

do a pc copper antenna is to create a footprint package to provide the

schematic connections and then put a polygon around the footprint and

fill it with copper.

 

This antenna is a folded F that operates at 2.4 Ghz.  Consequently it

has two connections, antenna and ground.  I named the polygon ANTENNA

which is also the name of the net that connects to it.  The other

connection is ground.  Eagle sees these two connections as being an

error since it is just copper between them but that is what the design

calls for.

 

As a consequence the antenna polygon will not fill.  At least I think

that is why it will not fill.  However, I did remove the ground

connection and it still will not fill.

 

Any ideas?

Hi John

You should be able to achieve what you desire. The work around (if you would

call it that ) is to name the 'net' to the feedpoint of the antenna GND  and

the antenna polygon GND also. So eagle should see no issues.

Why it will not fill is mysterious. If the SMD pads are inside the polygon

and both the net and the poly names are spelt the same the poly should fill.

Ensure the pour for the polygon is set to Solid as Hatch with a large

spacing may make the polygon appear unfilled.

You may have polygon ratsnest turned off. In the command line type SET POLY

ON
