Abstract
This paper presents the design of a rectangular patch antenna array for 5G wireless communication using CST microwave studio. Rogers RT5880 LZ dielectric with properties of h = 0.762 mm, e = 1.96 and δ = 0.0025 has been used as a substrate of the proposed design. The length of the single patch antenna is 3.0526 mm and width of the patch is 4.2352 mm. The distance between two antenna elements is 0.63λ. The side lobe level and half beam width of two element array are reduced as compare to a single element. The return loss of proposed design is less than −10 dB. The single patch antenna is working in the range of 26.5 GHz to 28.8GHz, having 8.2% impedance bandwidth and gain is 7.8dB. For two element antenna array, the impedance bandwidth is increased up to 28.86% and also gain is increased.
