How to add load resistance at the end of the cpw

Hi
I think when i had to do this a while ago to terminate parasitic patch antenna elements i simply drew a rectangular region accross the CPW to the ground plane and assigned it as a lump resistive element with an intergration line parallel to the length of the CPW slots.

Ie Imagine the CPW slots running parallel and then turning a u-turn to join up with each other. Across the gap at the 'u-turn' is were you want to draw your lumped resistive load rectangle. You can ten quite easily findout the resistance required to peoperly terminate your line.

Was a while ago and tis is from memeory though..
Hope it helps
