摘要

In this study, a 1×2 Circular Microstrip Patch Multiple Input Multiple Output (CMP MIMO) antenna configuration for wireless communication systems is designed, modeled, simulated and analyzed for 3.3 GHz. MIMO is essential for 4G, 5G, Wi-Fi and IoT applications because it improves channel capacity, spectral efficiency and reliability. Despite its size and ease of integration, microstrip patch antennas have drawbacks such as mutual coupling and bandwidth limitations. To improve isolation, the presented work involves coupling reduction strategies like parasitic elements, slots, stubs and defective ground structures (DGS). Ansys HFSS is employed to build the design of 82.6 mm×113.85 mm dimension and optimize geometry. Low cross-polarization and symmetrical radiation are provided by circular patch arrangement. Stable radiation performance, low envelope correlation coefficient and good isolation are confirmed by simulation and analysis. From the results it is found that Voltage Standing Wave Ratio (VSWR) value of 1.1152, Bandwidth of 690 MHz, Envelope Correlation Coefficient (ECC) and mutual coupling of −31.98 dB. This antenna is appropriate for portable wireless devices since it supports high data speeds.
