Investigation on radiation improvement of corner truncated triband square microstrip patch antenna with double negative material

Abstract

In this paper, we have reported a truncated square microstrip patch antenna loaded with double negative material and conventional dielectric material. Metamaterials exhibit qualitatively new electromagnetic response functions that cannot be found in the nature. The inclusion of these structures allows simultaneous operation over several frequencies. We have designed an antenna loaded with metamaterial to work in three bands in the frequency range of 0.5–2.0 GHz. The designed antenna loaded with metamaterial has three working frequency bands. We have shown a comparative analysis of this metamaterial loaded antenna with conventional antenna. The designed antenna loaded with metamaterial has several wireless applications. Design results are obtained by high frequency structure simulator, which is used for simulating microwave passive components.
