+Helical Antenna
+===============
+
+Introduction
+-------------
+**This tutorial covers:**
+
+* setup of a helix using the wire primitive
+* setup a lumped feeding port (R_in = 120 Ohms)
+* adding a near-field to far-field (nf2ff) box using an efficient subsampling
+* calculate the S-Parameter of the antenna
+* calculate and plot the far-field pattern
