Simple Patch Antenna
====================
Introduction
------------
A simple patch antenna for 2.4 GHz.
**This tutorial covers:**
* Setup a patch, substrate and ground.
* Setup of a lumped feeding port.
* Adding a near-field to far-field (nf2ff) recording box.
* Calculate the S-Parameter of the antenna.
* Calculate and plot the far-field pattern
