| Abstract | ||
| This paper presents two reconfigurable microstrip antennas with different sizes of the patch elements for Cogniative Radio (CR) network. The desired resonant frequencies can be controlled by using smart tunable permittivity materials. The switching among these frequencies depending on the CR requierments. A wide tunability range of switching frequencies covers the bands of Wi-Fi and Wi-Max standards are obtained. This rang of frequencies begin from 1.5 till 5.5 GHz. Variable permittivity concept with respect to (as a function of) external source has been assummed for switching through this study. The two geometry structures for the planner array antenna are investigated and simulated using COMSOL sofware. | ||
