Design and Simulation of An Octagonal Microstrip Antenna Array

 In this work, an octagonal microstrip antenna is presented. The design formulas of it are introduced based on the circular microstrip antenna. After presenting the theory of it, a single octagonal patch antenna is designed and simulated. After that, the designed antenna is developed to a 2×2 planar array. To evaluate the performance of the single and array antennas, the designed antennas are simulated using HFSS and the obtained results are presented.
