The aim of this report is to learn about dual-band antennas, and carry out electromagnetic simulations of pre-designed antennas using CST Studio Suite, a commercial software. We will replicate the structural models of three representative dual-band antenna designs extracted from the scienti c literature, and we will try to obtain the same results after the simulation. For this, we will rst search information about the antennas we are going to work with, then we will learn how to use CST from a tutorial article provided by our instructors, and nally we will discuss the results obtained. 2019/2020
