High Gain Patch Array Antenna for 5G Network Communication and IoT Applications

A new array of patch antenna is proposed in this paper for upcoming 5G networks and IoT applications. The operating frequencies are optimized at 4 different bands ranging from 30 GHz to 50 GHz. Such design is suitable for 5G communication applications for Multiple Input Multiple Output (MIMO) systems. The proposed antenna has a simple structure and it consists of two patches separated by a distance which can be optimized for required different types of parametric combinations. A single point feed is divided by using the Wilkinson's power divider model to split or combine the power transmitted to or the power received from two patch elements respectively. The designed array has shown comparatively high performance and better directional radiation patterns. The four operating frequencies are observed at 31.0 GHz, 36.4 GHz, 43.4 GHz and 48.5 GHz with simulated return losses observed with approximate values at 44.9 dB, -33.4 dB, -29.2 dB and -23.9 dB respectively. The simulated results show that the efficiency varies from 18% to 23%. The VSWR is very close to unity indicating a good performance of the antenna array. The performance is encouraging and the array antenna is suitable for the applications in upcoming 5G network communication and other IoT applications.
