Is ADS good for phased array of planar antenna with active elements for shifting?

I want to design a phased array antenna for 2.4 GHz and want to control it with PC. I intend to use rf switches for phase shifting. Can anyone please tell me if its a good idea to use rf switches. And which software should I use for simulation which should also have rf switches in library. I have some experience with ads 2009 momentum. Please help

Since there are active and passive parts in your design, using ADS is preferred. Of course you can use Momentum for antenna but EMDS which is 3D simulator (and integrated with ADS and Momentum) is preferred.
