Analysis of Large Array with Phased Array Antenna

Abstract

This paper gives an overview to design array antennas by using phased array antennas. Antenna arrays of large scale have a variety of applications which include massive MIMO applications for 5G technology. Using a Phased sub array it improves gain, directivity bandwidth of an antenna, performance of link reliability and data rate. It presents the design and analysis of antenna arrays of large scale. It is simple and more efficient with implementation of techniques by phased sub arrays to improve the analysis of array antennas with large scale [1]. Repeating small sub arrays multiple times, antenna arrays of large scale can be designed. Using MATLAB software, a sub array is designed for 2x2 (4 elements) and 4x4(16 elements) is analyzed with various parameters like bandwidth, gain and directivity. The results are analyzed with array elements, sidelobes, directivities and High-power bandwidth. Using these results design large array with sub phased array.
