3.4 Setting up the mesh

At this stage we should define the mesh. We open Mesh Settings dialogue by pressing Settings button in the Model tab and we can determine the cell size in each direction. Let us set the cell size according to the criterion of 10 cells per wavelength. The maximum frequency considered for the antenna is 30 GHz, which corresponds to a cell size of 1 mm. The mesh settings for the considered scenario are shown in the picture below. After pressing OK button the mesh will be generated.
