Design of a High Gain Broadband Microstrip Patch Antenna for Cognitive Radio | Original Article
This research paper presenting the experimental investigations on the effect of metallic inclusions on a dielectric substrate for tailoring the properties of met materials and a dual band micro strip patch antenna along with the met material structure that is proposed at a height of 3.3 mm from the ground plane, which consists of a geometry incorporated with a special arrangement that is c fashioned arrangement Actually this research paper principally paying attention on going up the probable parameters of high gain broadband microstrip patch antennas and analyzing the dual band procedure of the proposed antenna. dielectric properties of samples are measured with dissimilar metallic inclusions and the outcome are compared with and without inclusions. The proposed antenna is designed to resonate frequency at 2.488 GHz and 2.920 GHz frequency and the impedance bandwidth of the antenna is at 2.488 GHz along with the proposed met material structure is improved with 20.5 MHz frequency and return loss is reduced by the 20.138 dB. At 2.920 GHz frequency the impedance bandwidth is improved by 25.5 MHz and return loss is reduced by 19.574 dB. For verifying that the proposed met material structure possesses the designs of several samples leading negative valves of Permittivity and Permeability within the operating frequency ranges presented along with their experimental results.
