Design and Fabrication of compact wideband Antenna for Cognitive Radio (CR) Applications
Cognitive radio (CR) is a form of wireless communication in which a transceiver can intelligently detect which communication channels are in use and which are not, and instantly move into vacant channels while avoiding occupied ones.
This optimizes the use of available radio-frequency (RF) spectrum while minimizing interference to other users. Smart antennas are mostly used to be employed in cognitive radio. Two wideband antennas and two ultra wideband CPW-fed antenna were designed, simulated and fabricated. The simulated results were validated by measured ones achieved in UK. The designs were reported as a master thesis entitled "Designing wideband antennas for cognitive radio".
