Design and Implementation of Circular Microstrip Patch Array Antenna for 5G Communication Using Rogers RT5880

The significance of communication equipment is to attain high accuracy with miniature size. In this research, an array of circular microstrip patch antennas (CMPAs) is designed for future 5G mobile data networks applications and it is suitable for 5G technology with mm wave antenna systems. The resonance frequency of the proposed antenna is 28 GHz and it is constructed using a Rogers RT5880 substrate with a $\epsilon_{\mathrm{r}}$ 2.2, a loss tangent of 0.0013, and a height of 0.508 mm. Patch with diameter 2.02 mm and substrate with size 8.08×8.08 mm-, Here it is shown the miniature antenna with minimal return loss and high gain. Using HFSS Software the simulated results are S11 = -16.2dB, gain is 7.5dB obtained for a single circular antenna, return loss = -18.5dB, gain is 8.8dB for a two-array antenna, return loss = -21.6dB, gain is 9.6dB for a four-array antenna.
