Optimized Octagonal Shaped Antenna using Split Ring Design and Analysis for Wireless Communication Applications

This paper proposes an Octagonal shaped planar antenna design and its performance in wireless communication applications by using split ring technique as a reconfigurability. The proposed antenna has a dimension of 22x26x1.6 mm(3). The frequency bandwidth obtained after simulation is 2GHz-10GHz. The prototype antenna is fabricated on the FR4 high-frequency substrate over 70 x 70 mm(2) board. This antenna was measured by Vector Network analyzer for the maximum frequency of 10GHz, compared with the simulation results and reasonable agreement was obtained. Split ring technique is introduced on the patch, to filter unwanted frequencies. Simulation Gain plot confirms that particular range of frequency is suppressed.
