Abstract:
This work had the goal of designing active antennas and impedance adaptation circuits, both operating at the frequency of 2.45 GHz. A very important point to be taken into consideration is the fact that the adaptation network was designed to achieve the matching for a large number of the antenna's impedance and that this impedance is complex. Once it is determined the impedance matching, we used the software CST Microwave Studio for the 3D electromagnetic modeling required for the determination of the spreading parameters and space resolution of the radiation diagram. It was reached the adaptation for an antenna with inductive characteristics and another antenna with capacitive characteristics, bringing a better performance for both.
