Abstract
With the growing demand of mobile and wireless users, there is a need to switch from fourth generation (4G) to fifth generation (5G) wireless technology for better data rate, coverage, and spectral efficiency. In 4G technology, data rate is around 1.0 Gbps, but in 5G technology data rate is more than 1.0 Gbps to reduce delay and latency. A properly implemented array can enhance the gain in 5G technology. A 2:1 VSWR-based array antenna with a single element is designed on the Rogers RT Duroid 5880 substrate to cover the 27.06–28.35 GHz frequency band for 5G application. The dimension of the substrate is 51.44 × 18.34 mm2. The approximate size of each patch is 3.8 × 4.5 mm2. The proposed array antenna has 16.07 dBi gain, 93.5% radiation efficiency, and 93.5% total efficiency at the 28.0 GHz resonant frequency. MEG for Gaussian medium with XPR = 0 dB is in the range of −9.85– −13.05 dB, while with XPR = 6.0 dB, MEG for Gaussian medium lies in the range −7.50– −10.71 dB.
