The Fifth-Generation (5G) wireless communication has brought in a new age of high-speed, low-latency connection. 1×4 Circular ring array antenna is intended to function at millimeter-wave frequencies, similar as 28GHz. The ANSYS (HFSS) Software tool is used to simulate and examine the main characteristics of the antennas: gain, return loss, Voltage Standing Wave Ratio (VSWR) and the radiation pattern. In this antenna design we used Rodger RT Duroid 5880 substrate because it has excellent electrical characteristics, little loss and strong thermal stability.
