Hello everyone
I am trying to plot the radiation efficiency of a patch antenna vs thickness of the substrate. I want to see the effect of dielectric loss, conductor loss and surface waves on the radiation efficiency.

Does anyone know how to calculate surface waves for patch antenna with different substarte thicknesses.


Thanks

Re: HFSS - Microstrip patch antenna (surface wave calculatio

To find the relation between radiation efficiency and the thickness of the substrate, I suggest to use microstripes. By my experience, it is easy enough to plot the radiation efficiency vs thickness of the substrate. Using microstripes, you can look the radiation efficiency from the graph of radiation pattern. From this graph, we can look directly the radiation efficiency and antenna efficiency. By changing the thickness of the substrate you can get the different result, so that you can plot it easily. I hope it can help you.
