Efficient Design of Bi-circular Patch Antenna for 5G Communication with Mathematical Calculations for Resonant Frequencies

  • 14 Accesses


In this paper the conventional circular patch has been reshaped by two circular arcs with the FR4 Epoxy material for substrate. This is supported by the mathematical calculations of resonant frequencies with the help of Bressels function. The proposed antenna has been designed and simulated using Ansys HFSS version 15 software. The modifications which are implemented on the conventional circular patch leads to a unique geometry having two arcs separated by a certain distance. Here an optimized distance, equal to the free space wavelength λ0 has been taken into account. An optimized circular slot is also implemented to enhance the bandwidth. The simulated and the measured results of the parameters like S11, VSWR have been compared. The results for the antenna gain, directivity, radiation efficiency also included in this paper. 15 GHz design frequency has been chosen as it is allocated for the 5G communication.
