Abstract :
The proposed micro strip-feed antenna consists of glass shaped with defected ground structure for cognitive radio application. The proposed antenna uses FR-4 substrate having thickness of 1.6mm and dielectric constant of 4.4. By using two switches a combination of wideband and narrowband antennas into the same substrate is designed. The antenna can be used as a wideband antenna when both switches are in on position. Micro strip-fed planer glass-shaped monopole operates from 2.6 GHz to 12.6 GHz which is used as a sensing antenna. The narrowband antenna designed to operate from 9.4- 12.08GHz (s1 on, s2 off), 6.68-9.4GHz, 10.76-12.37GHz (s1 off, s2 on), 9.62-12.62GHz, 4.09-4.2GHz (s1 off, s2 off). The proposed antenna was designed by using software HFSS 13.0 (Higher frequency simulation software).
