A New Design of 5G Planar Antenna with Enhancement of the Gain Using Array Antenna

In this paper, an antenna array with 32 radiating elements was designed, analyzed, and simulated using ADS and using CST Microwave Studio electromagnetic solvers so as to investigate the effects of various factors on the antenna’s radiation characteristics. The square patch antenna is printed on Rogers RT5880 substrate, with a relative dielectric permittivity of 2.2, a loss tangent of 0.0009, and a thickness of 0.508 mm. The dimensions of the single element are 28.1 × 28.1 mm2. The results obtained present a good matching of input impedance around 3.5 GHz, a reflection coefficient of −23 dB, a high gain of 20.5 dBi, and a directional radiation pattern. The effect on the antenna parameters due to the increase in antenna elements (array) is observed in the antenna gain and directivity. This structure offers good performances which makes it suitable for sub-6 GHz wireless communication technologies of the mobile fifth generation (5G).
