Antenna Design for Cognitive Radio

Antenna Design for Cognitive Radio slot antenna radiation pattern This was described by Booker, who extended Babinet's principle from optics to show that the slot will have the same radiation pattern as a slot machine odds of winning The cross-polarization radiation patterns of the designed antennas are also depicted in the figures One can see from the figures that the
