5G Antipodal Reconfigurable Base Station Antenna for Modern automobile tracking applications

Abstract

This paper presents antipodal dipole antenna which is also a base station antenna which is highly suitable for tracking an automobile especially cars/trucks. This antenna contains 4 planes, including the reflector plane, brick on which two poles are present. The Gain of the antenna is around 6.9 to 7.1 dB based on the width of the dipole of the antenna. The directivity remains the same in all width of the dipoles and the S11 parameters values changes as of the width of the dipole. Comparatively the antenna has a good gain and S11 values in frequency 6.5 GHz at the dipole width of 4mm. This antenna finds its way in medical fields to improve the communication inside the automotive vehicles. The proposed antenna is a reconfigurable antenna, which has good gain at multiple frequencies. The reconfigurable is made possible using Metamaterials. The Antipodal structure of the antenna is due to presence of multiple planar types in the antipodal structure of the antenna. Even if the frequency not properly received by the antenna, the reflector plane reflects the frequency towards the one plane at the back of the brick, so the gain is maintained at a desired level.
