Design of a Compact Circular Patch Antenna Operating at ISM-Band for the WiMAX Communication Systems

In recent times, people’s dependency on high-speed internet has increased to a significant extent through the means of Wireless Communication Systems. However, in developing and underdeveloped nations, it is a common scene that rural areas do not receive proper internet connectivity due to their price ranges and implantation costs. Considering this issue, a Circular Patch Antenna has been designed in this Research work for WiMAX Communication Systems using FR-4 Substrate Material with an Operating Frequency of 2.45 GHz (ISM-Band). The whole Simulation of the Antenna was carried out in the CST Studio Suite 2019 Software. Pure Copper Material was used to create the Ground Plane and the Circular shape Patch of the Antenna. The simulated Patch Antenna Model has an Architectural Dimensions of 20.66*26.76 mm2, which has been thoroughly compared with the past Research works to justify the validity of the work. Some of the Parameters that are obtained from the Simulation include-Return Loss (S1,1) of -37.198 dB, VSWR of 1.0282, Surface Current of 175 A/m, and other vital parameters were also successfully determined, which proves that the Antenna can be a better choice for WiMAX Communication Systems.
