Is there any constraint/mathematical support for choosing a substrate for desired frequency bands. Can we specify the lower and upper cutoff frequencies of a substrate by knowing their dielectric constant and loss tangent?
What are surface wave modes? How can we calculate them for a particular substrate to design the microstrip antennas? Kindly provide the mathematical expressions.

Giving lumped port and simulating the antenna having very less substrate thickness such as 0.1mm or lesser is difficult to simulate. In this regard I would like to know the best port method in HFSS.
