Design and Optimization of an Antenna Array for future 5G Applications using PSO Algorithm

In 5G mobile communication systems, mm wave communication has become one of the most attractive techniques reason being a huge increase in wireless data traffic. Also, the mobile terminals have become thinner and in functionality, more versatile and continue to become more. A mobile terminal, nowadays consists 2G-4G antennas, NFC antennas, Wi-Fi antennas, and now 5G antennas as well. Thus, compact antenna arrays are required and are a very hot topic today for future mobiles. optimization technique has been used in this paper since it includes the searching and obtaining of the perfect solution possible for a given problem. In this project we’ve first proposed a rectangular patch antenna of size 3.237 mm $\times 2.8$ mm $\times 0.5$ mm with which a $1\times 4$ antenna array has been designed of the dimensions 9.787 mm $\times 34.76$ mm $\times 0.5$ mm. This $1\times 4$ antenna array was optimized using Particle Swarm optimization (PSO) and the parameters have been analysed and discussed. Dimensions are 13.237 mm $\times$ 47.76 mm $\times 0.5$ mm.
