ABSTRACT

All mobile base stations are characterized by antennas which are mostly dipole antenna based. Nigeria is one of the big market in mobile communication industry but unfortunately all major infrastructure required in this industry are imported from other countries of the world. This paper presents dipole-based antenna design and simulation for LTE Nigerian networks. This is a step towards the production of a Nigerian-made mobile base station antenna.  A single dipole as well as 4 and 8 dipole arrays were simulated and results show a maximum gain of 2.1dBi, 9.1dBi and 12.3dBi respectively. A microstrip patch antenna as well as 2 and 4 patch arrays were also simulated and results show a directional radiation pattern with maximum gain of 10.1dBi for a single patch antenna and 11.4dBi and 13.4dBi for 2 and 4 patch arrays respectively. In both cases, antennas resonated at the designed frequency of 2.6GHz with a return loss of less than -14dB for dipole and -23dB for microstrip which are below the required benchmark of -10dB. All simulations were carried out and optimized in MATLAB. Results have shown that these antennas are suitable for small cell mobile base station applications and with good beam-steering mechanism, can also be deployed to other applications like localizations systems.
