Re: gEDA-user: PCB antenna pattern

I am designing a zigbee interface, and I am using an inverted F antenna

pattern are shorted (well not on 2.4GHz), so I don't have any clue what
to put to the schematic. So far, I simply grounded the antenna pin of
the transceiver, but it can lead to misunderstanding. The other option
is to have a two-pin symbol, but the pattern will cause short circuit
when running the DRC.

Any suggestion?


Can't you make the antenna in a component as multiple pads? Then it would be connected just like any other component pads.

If there is no way to make the antenna out of pads, perhaps you could create pads that are very tiny so that they can be connected by traces without changing the outline. Pad A would need to overlap pad B. Then separate nets could connect to the two pads without the software thinking they are shorted.

If the tools won't let you have pads touching inside a part, I guess this won't work.
