Design of a Wide Band Circular Patch Antenna for WiMAX, C-Band and 5G Sub-6 GHz Communication Applications

The Advancement of Fifth-generation of Wireless Communication System Necessitates Sophisticated antenna designs capable of supporting increased band-width, Higher data rates, and low latency. This Paper Invokes the design and analysis of Circular Patch Antenna for WiMAX and 5G C-Band applications Operating within the 5G Sub – 6GHz Spectrum across frequency bands of N77 (3.3-4.2GHz), N78 (3.3-3.8GHz), N79 (4.4-5GHz). As communication network evolve towards higher frequencies and faster data rate. The Antenna is outlined on FR-4 Epoxy material in co-ordination with Dimensions of 30mm x 24mm x 1.6 mm. This antenna focuses on Single element circular patch antenna with S-paramters, VSWR, Radiation Pattern are analyzed in both 2D and 3D plots. The design and simulation were conducted using CST Studio Suite. The results demonstrate that the proposed antenna is a promising candidate for Sub-6 GHz 5G and WiMAX communications, offering enhanced performance, compact size, and reliable operation.
