Smart Wideband Sensing Antenna for Cognitive Radio Applications

The association of quantum effect into microwave application has become protagonist of modern era of wave applications. The effective impedance variation may easily be encountered with respect to alteration into path distribution of E-M wave. The effect of quantum theory is directly affected with respect to band gap insertion in various materials with different dielectric constant. In this paper the antenna designed is constituted by band gap insertion, resulting in better trade off in size and bandwidth calculations. The antenna geometry is also modified to reduce overall captured area. The passive geometry with respect to patch gives reradiating current distribution and hence results in improved bandwidth of micro strip patch antenna about 32.05 percent at operating frequency 2.31 GHz. The Scattering loss parameter S11 is measured. The antenna is widely suitable for large number of advance applications such as cognitive radio sensing network, IoT and smart wide RF scanning devices as per FCC standard.
