“…The spectral efficiency of a system can be enhanced by improving the SINR, and it can also be improved by adding more number of cells in a system, given a healthy SINR is maintained after adding more cells. For comparing the relative system capacity (spectral efficiency) gain with respect to the reference case, the relative gain (G Rel ) of system spectral efficiency in percentage is computed as follows [4]:…”

“…In case of switched beam antenna, multiple narrow beams overlapping over each other cover a wide sector. As all the signal energy is not directed towards main lobe of the antenna, some of the energy is spread through the side lobes and hence causes an increase in interference level [4].…”

The main target of this paper is to evaluate the performance of a switched beam antenna in a macro-cellular environment at 28 GHz frequency. Another objective of this study is to compare the performance of a cellular system equipped with 7-beams switched beam antenna with conventional system implemented with wide 65 • horizontal HPBW antenna. A campaign of 3D ray tracing simulations was carried out by using realistic 3D building data. Performance metrics considered for this study are RX level, SINR, system spectral efficiency, and the relative gain. Different configurations of 7-beams antenna is studied and the advantages and the disadvantages of considered configurations are highlighted in this paper. It is learned from the acquired results that an optimal configuration of 7-beams antenna can provide upto only 209.72 % of relative gain with respect to a traditional 3-sector site deployment. However, the relative performance gain of a 7-beam antenna can be negative under certain circumstances. Index Terms-Switched beam antenna; performance analysis; 3D ray tracing; macro cellular; 5G.
