Abstract
The objective of this project was to research and develop a Cognitive Radio System. Cognitive Radio is a wireless system that adapts to its environment to find the optimal frequency channel to provide fast and efficient communications for data transfer and to extend the battery life of the radio system due to lower power usage. Two main parts will make up this system, that being a frequency reconfigurable antenna or tunable antenna and a radio control system. Frequency reconfigurability can be achieved by changing the physical length of the antenna radiators using devices such as discrete switching mechanisms such as the digitally tunable capacitor or RF switches. The antenna will also provide a control interface for the transmitter control subsystem. An SDR will be used as the platform for the radio transmitter design. A control system will be implemented to detect (using a VSWR detector) and adjust the characteristics of the system based on the dynamic properties that are continuously being tracked by the antenna, and will also drive the control interface of the antenna subsystem.
