Cognitive radio, ultra-wide band, narrowband, return loss



The idea of this paper is to design a dual port ultra-wide band antenna integrated with reconfigurable narrow band antenna for cognitive radio applications. The narrow band antenna is a microstrip patch antenna attached at the back side of the ultra-wide band octagonal antenna. The ultra-wide band senses over the frequency range of 3.91 – 11.29 GHz. The Narrowband reconfigurable antenna is seen to operate at 6.39GHz, 6.90GHz, 7.81GHz, 8.94 GHz. Isolation between both the ports is kept less than -15 dB over entire operating band. Reconfiguration is done with the help of pin diode. The antenna switched from ultra-wide band to narrow band by switching ‘ON’ the pin diode.
