Cannot get antenna polygon to fill

autodeskguest

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?

    It sounds like you added the polygon to the board instead of making it part

    of the package.  If it were part of the package you can put the two pads

    wherever you want and they will connect.  However, you'll get massive DRC

    errors.
