It has been a while since I studied Antenna theory but I dont remember anything that said a flat antenna was superior over stub antenna</p>
if it is why is every other manufacturersticking with more traditional antennas?</p>
Can you give me a steer to the appropriate theory?</p>

Mike,
Take a look at any patch antenna that gives you more gain than the 3 dB of an omni and you will see that they are flat...

Patch antennas like the ones obviously used in the Weatronics system give you somewhere around 6 to 8 dB gain in the primary direction of the antenna.
