Abstract
Design of tri-band hexagonal patch antenna for wireless applications is presented in this paper. The proposed antenna is operated at ultra-wide band at 4.2 GHz, 7.2 GHz, and 10.42 GHz frequencies at wireless applications. The coplanar waveguide (CPW) feeding is considered and slits at four sides and hexagonal split are etched at the center of the patch to operate tri-bands. The proposed antenna parametric analysis has carried out for optimized design. The parametric analysis considered with two parameters and presented in the design. The proposed antenna radiation pattern is observed for E-plane and H-plane at three bands and presented in the results. The gain 3D plots and current distribution plots are also presented in the results at tri-bands. The proposed antenna is fabricated and tested. The simulation results of reflection coefficient with measured results of reflection coefficient are presented. The comparison table is also presented with present work to existing works. These tri-bands are useful for wireless applications.
