In this research, a two-port circular patch multiple-input multiple-output antenna with a defective ground architecture for WiMAX applications is designed and the results are studied. For WiMAX applications, this antenna operates at frequencies ranging from 3.0 to 3.6 GHz. WiMAX technology necessitates antennas with varying performance characteristics such as gain, bandwidth, return loss, error correlation coefficients, and segregation between two ports in MIMO arrangements. Because of its compact nature, the circular form of the patch adapts better than other shapes. The H-shaped DGS integrates considerably, improving the separation and interconnection between two parts. This suggested antenna design employs line feeding on a FR4 substrate with a dielectric constant of 4.4. Also, apply HFSS simulation to determine the antenna’s efficiency. The recommended antenna design maintains antenna characteristics, particularly return loss.

摘要

In this research, a two-port circular patch multiple-input multiple-output antenna with a defective ground architecture for WiMAX applications is designed and the results are studied. For WiMAX applications, this antenna operates at frequencies ranging from 3.0 to 3.6 GHz. WiMAX technology necessitates antennas with varying performance characteristics such as gain, bandwidth, return loss, error correlation coefficients, and segregation between two ports in MIMO arrangements. Because of its compact nature, the circular form of the patch adapts better than other shapes. The H-shaped DGS integrates considerably, improving the separation and interconnection between two parts. This suggested antenna design employs line feeding on a FR4 substrate with a dielectric constant of 4.4. Also, apply HFSS simulation to determine the antenna’s efficiency. The recommended antenna design maintains antenna characteristics, particularly return loss.
