Reconfigurable Filtenna For Cognitive Radio Applications, Maria Elizabeth Zamudio
Electrical and Computer Engineering ETDs
In order to improve the efficiency of the spectrum usage (available idle spectrum), cognitive radio devices should identify their environment, work in conjunction with other cognitive radio devices, and reconfigure themselves. The concept that becomes crucial when designing cognitive radio devices is reconfigurability. Active components are used as switches in order to transform a device into a reconfigurable one. However, when switches are applied to an antenna design, we are not only making it reconfigurable, but we may also be affecting the electromagnetic properties of the reconfigurable communicating antenna. An alternate solution is presented in this thesis based on a …
