Abstract

In this paper we present a compact microstrip antenna with an ultra-wide frequency bandwidth. The ultra-wideband characteristic is obtained by applying the metamaterial concept to an ordinary rectangular microstrip patch antenna with a limited bandwidth of 0.225 GHz. This concept consists of embedding the metallic parts of the antenna, patch and ground plane, by repeating the patterns of a unit cell. The unit cell, designed with different pattern shapes on its upper and lower layers, verifies the metamaterials criterion by means of the dispersion diagram, showing the phase velocity and the group velocity oppositely directed. The new antenna, resulting from this operation was designed and simulated by means of CST Microwave Studio. To attest this approach, the design of the new antenna was experimentally verified after fabricating it on the Rogers RT5880 substrate (εr = 2.2 and h = 0.787 mm) and measuring its characteristics.
