This paper presents a single antenna structure design to switch between UWB and four narrow band frequencies. The antenna consists of rectangular patch with curved shape on one side and switchable band pass structure on other side. Proposed antenna is very much suitable for cognitive radio applications. Antenna operates in five states. One state of antenna is operates in wide band which is used for channel sensing and remaining four states operates in narrow band frequency which is used to communicate over a desired frequency band. Its performance evaluation is carried out with the help of simulation and physical verification and the results are presented.

Abstract


This paper presents a single antenna structure design to switch between UWB and four narrow band frequencies. The antenna consists of rectangular patch with curved shape on one side and switchable band pass structure on other side. Proposed antenna is very much suitable for cognitive radio applications. Antenna operates in five states. One state of antenna is operates in wide band which is used for channel sensing and remaining four states operates in narrow band frequency which is used to communicate over a desired frequency band. Its performance evaluation is carried out with the help of simulation and physical verification and the results are presented.
