The Patch refers to a rectangular patch on the xy-plane composed of wires having a flat or rectangular cross-section. Use this wire grid to model patch and microstrip antennas.

Go to Draw > Wire Grid > Patch in the main menu to display the Draw dialog box for the Patch. There are three pages: Patch, Attributes and Materials.

The Patch page

In the Patch page the geometrical parameters for the Patch can be set, Fig. 1. The Patch is defined by giving the coordinates of two opposite corner points in the xy-plane (z = 0), as shown in Fig. 2.

Once the geometrical parameters in the Patch page have been set, the Attributes page can be chosen, where the number of facets of the Patch can be entered. Refer to Wire Grid Attributes > to see other parameters that can be set in the Attributes page. Refer to Wire Materials > to see the parameters that can be set in the Materials page.
