Antenna gain determination using a microwave CAD tool - HFSS

Antennas have been increasingly studied in recent years. Different antennas have been designed for different applications based on the characteristics of the receiving side. Antennas cannot be fabricated as such and then be studied on. This leads to waste of material and requires a lot of iterations until we get the final design. In order to study the characteristics of an antenna without fabricating it, we need a special tool called a ldquoSIMULATOR TOOLrdquo. It can determine all possible characteristics of an antenna under test. In this paper wepsilall be simulate few of the antennas using HFSS simulator tool.
