AB  - This study focuses on the design and analysis
of a reconfigurable antenna that can be integrated into the
CR systems. A dual-port &ldquo;interweave&rdquo; CR antenna system
in which an antenna structure is proposed and designed.
This design is composed of an elliptical disk radiator
sensing antenna that covers a frequency range of
(1.8-11) GHz and a dual-band reconfigurable
communicating antenna in the form of a modified
dual-band rectangular radiator. By controlling the length
of a stub attached to the communicating antenna with the
aid of two PIN diodes, the dual-band antenna can
reconfigure its resonant frequencies to (2, 2.2 GHz),
(3.25, 3.8 GHz) and (4.3, 5.6 GHz).
