Cognitive Radio presents promising applications in creating a more intelligent and flexible radio and wireless system structures considering the increasing demands faced by spectrum usage and spectrum regulators for specific frequency bands. The flexibility and reconfigurability required by such systems place a significant burden on engineers and radio(More)
A simple UWB microstrip monopole antenna with reconfigurable multi band function is presented. Reconfigurability is achieved by using multiple switches to control the length of different printed stubs. Reflection coefficient, radiation patterns and gain measurements are presented to verify the simulations. Finally the total efficiency of the antenna is(More)
