Abstract:
Cognitive Radio (CR) is a new paradigm which
promises to yield an improved quality of service for the user
whilst also enabling more intensive use of the available radio
frequency spectrum. CR will require integrated widenarrowband
antennas for performing the search and
communications functions. This paper helps to address this need
by providing a new antenna which can be reconfigured between
a narrow and ultra-wide impedance bandwidth. The final section
of the paper demonstrates an ultra-wideband antenna having a
variable lower cut-off frequency.
