  Mini-project

  This mini-project assignement is composed of two parts:

  1. Plot of the antenna patterns.
  2. Use of CST to simulate monopole abobe ground plane.

  The due date for both part is 28/12/2017 and please deliver it to your TA.

  Descriptions of these parts are in the PDF documents.
