Hi gheit

The edge port you used in the model above seems reasonable as it excites the structure between the center line and the ground correctly.

While the above should give you reasonable results, if you wanted to compare very accurately with measured results, you might have to model the actual physical feed in more detail. In the paper you reference the CPW was excited by a SMA connector and you could include this geometry - excited by a waveguide port for example - in your model. Please see the image below for an example of this.
