DESIGN AND ANALYSIS OF ANTENNA ARRAY ON CURVATURE SURFACE FOR 5G APPLICATIONS

Abstract

In conjunction with the advancement of wireless communication technology, 5G can be considered as an upcoming new generation in the field of wireless mobile systems. Within this project, an antenna array with coaxial feed has been designed and simulated at Ka band (35GHz). The purpose of designing an antenna array is that it has better gain & bandwidth as compared to the microstrip patch antenna. Further, the designed antenna array which comprises of 8 antenna elements with a consistent spacing conformed on a cylindrical, conical and spherical curvature surface. A study on parametric analysis by varying the radius of curvature, thickness of substrate and relative permittivity has been done in terms of return loss and gain. By modelling and simulating the design, observations were made that return loss of the conformal array is less than -10ⅆ𝐵 , narrow bandwidth and better gain has been achieved which meet the requirement of enhancing the antenna performance. The proposed antenna design and its parametric analysis is simulated through HFSS 3D simulation tool.
