CPW-Fed Wideband Microstrip Antenna: The OctaWave Design

This paper discusses about the design and simulation results of a coplanar waveguide (CPW) fed octagonal microstrip antenna tailored for WiMAX applications in Indonesia. With a gain ranging between 1.83 – 2.02 dBi and exhibiting a unidirectional radiation pattern, the proposed antenna fulfills the requirements for WiMAX operation in dual frequency bands. The antenna, employing an FR4 substrate with a dielectric constant of 4.554, features dimensions of 32 mm x 44 mm. Simulation analysis demonstrates its wide bandwidth spanning from 2.33 GHz to 3.43 GHz.
