Design of a High Gain Broadband Microstrip Patch Antenna for Cognitive Radio

Abstract

This research paper presenting the experimental investigations on the effect of metallic inclusions on a dielectric substrale 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 1he ground p lane, 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 micro.strip patch antennas and analyzing the dual band procedure of the proposed antenna. die lectric properties of samples are measured with dissimilar metallic inclusions and the outcome are compared 1 ilh and without inclusions. The proposed antenna is designed to resonateji0 equency at 2 . ./ GHz and 2.920 GHz frequency and the impedance bandwidth of the antenna is at 2.48 GHz along with the proposed metamaterial structure is improved with 20.5 MHz frequen cy 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 metamaterial structure possesses the designs of several samples leading negative values of Permittivity and Permeability within the operating frequency ranges presented along with their experimental results.
