In order to increase bandwidth appropriate for C and X-band applications, the paper presents a multiband antenna etched with many slots on the top patch surface with an octal defective ground structure. Utilizing the radiofrequency sputtering process, the antennas are coated with nanomaterial to improve their properties relative to uncoated antennas. For the proposed antennas (fr1 = 5.92 GHz, fr2 = 9.76 GHz, and fr3 = 12.61 GHz for MSMSADGS and fr1 = 5.95 GHz, fr2 = 9.88 GHz, and fr3 = 12.22 GHz for NCMSMSA-DGS), three distinct independent resonances are found. Along with improved radiation and return loss characteristics, the antenna showed a 40.2% increase in bandwidth.
Antennas are vital for wireless communication because they allow signals to be sent from one point to another, either in indoor or outdoor environment. The indoor wireless sector benefits greatly from the use of microstrip antennas, which are tiny, easy to manufacture and substrate conformal. Due to these advantages, microstrip antennas are used in a wide range of applications for their numerous design options, including planar, array and feeding (Bahl and Bhatia, 1982; Gauthier et al., 1988; James and Hall, 1989; and Ellis, 1999). They are compact, flexible and suitable for smart antennas. The applications are quite interesting and promising because of the ultrawideband capabilities and beam guiding of the microstrip antenna. These are used in a variety of applications that call for high performance, reasonably priced planar antennas such as imaging array, phased array and collision avoidance radars.
