Analysis of beam steering quality of 2-dimensional microstrip patch antenna array

The analysis of scanning range for both planar and circular array antenna in 5G application is presented in this research paper. Radiation pattern and scanning angle range of these antenna arrays and enhanced for RF receiver front-end application. A single array consists of various subarrays which represents vertical and horizontal linear arrays of radiators. These radiating elements have prescribed magnitude and phase distribution. They determined the range and shape of radiation pattern in both vertical and horizontal directions. Analysis of directive properties and range of scanning angle of those arrays shows that for small base stations, adaptive arrays with 5 subarrays, the circular configuration is more preferred as compared to planar array, because planar configuration has limitation with scanning angle 120°. Due to different geometry with some degree of curvature, circular configuration allows the beam steering in wider angular range up to 150°. It has wider beam and less directivity as compared to planar array.
