Parametric Study of Ring Coupled and Strip Connected Ring Coupled With Different Orientations for Wireless Multiband Applications
Abstract
A ring coupled rectangular microstrip patch antenna (RC-RMPA) and Strip connected ring coupled rectangular microstrip patch antenna (SCRC-RMPA) with different orientations for dual, triple and multiand applications in the frequency range of 2-12 GHz are developed. Based on the surface current distribution antennas are analyzed for the possible dominant and higher order resonance modes. Further SCRC-RMPA with four orientations of 0o (along the length axis of the patch antenna), 90o, 180o and 270o is analyzed. These orientations increase the length of the surface current leading to decrease in dominant mode resonance and possible redistributation of higher order modes leading to multiple resonances. The proposed antennas are simulated using 3DEM of Mentergraphics and validated using Vector network analyzer.
