A four-port multi-operational antenna system is designed for Cognitive Radio application. It consists of a sensing ultra-wideband antenna and three communicating narrowband antenna. The CPW fed monopole is a sensing antenna. It covers 2-11 GHz of the UWB band. The three narrow band antennas are operating at 5.834 GHz, 6.42 GHz, 7.355 GHz, and 8.786 GHz respectively. The mutual coupling is below-15 dB. This integrated UWB/NB antenna system can also be a good candidate for C-band, Maritime radio navigation, and X-band applications.
