Abstract

In this paper a dual band antenna operating in S band and C band is designed and developed with the help of metamaterial planar structure. Incorporating metamaterials in the conventional microstrip patch antenna improves the performance and reduce the size of the antenna. The proposed antenna has the dimension of 21.7mm X 20.4mm which is designed on FR4 substrate with microstrip line feeding. Further, the performance of the antenna is analyzed by varying substrate thickness. From the analysis, it is noticed that the proposed antenna has better performance when the substrate thickness is 1.6mm. It resonates at 2.7GHz, 7.5GHz with the return loss of -17.27dB, -29.63dB, respectively. It can be used for space communication (2.025GHz–2.110GHz) and for RADAR applications.
