No matter what your talking about some kind of micro-controller. A Motor driver and some kind of sensor.

Radio signals tend to be somewhat omni-directional - i.e. they spread out everywhere so you might well look at Ultra sonic or even Light or Infrared.

These can be detected by 2 sensors and the car directed to turn towards the stronger signal.

How to go about this in detail - there are so many variables it is something your going to have to research and get into the technology as there isn't a handy off the shelf solution.
