Optimized Wideband Microstrip Antenna Design: Octa Wave for CPW Applications

This study presents the design and simulation outcomes of a coplanar waveguide (CPW)-fed octagonal microstrip antenna, optimized for WiMAX applications specific to Indonesia. Utilizing an FR4 substrate with a dielectric constant of 4.554, the antenna features compact dimensions of 32 mm × 44 mm. Simulation results reveal a broad bandwidth covering 2.33 GHz to 3.43 GHz. The antenna exhibits a gain ranging from 1.83 to 2.02 dBi and a unidirectional radiation pattern, meeting the dual-band operational requirements essential for WiMAX services. The proposed design offers an effective solution for enhancing wireless communication within the specified frequency ranges.
