Using the 'Configure Physical Nets' tool in Altium you can merge copper touching a certain net with that net to avoid getting shorting violations. But I am trying to create a PIFA (inverted F-antenna) which has a ground point and also the active antenna point. So there is a pad for ground, another pad for the RF connection, and there is a complex antenna shape between them. Although at 2.4Ghz the GND and RF pads have different potentials, as far as Altium is concerned the pads are tied by copper and it wants to make it all a single net if I try to use the configure physical nets tool. Is there a way to avoid this? If I don't do this step it works, but I get violations and I would like to remove them.

Thanks
 

It is the same as connecting DGND and AGND to a common point in star grounding scheme. You make a symbol with two pins and a footprint with 2 pins with a short piece of line between them. It is often called a net link.
You get to have two nets but it is a solid copper trace on the board.
