Capacity and SNR Analysis of a Millimeter Wave Cellular Network with Phased Antenna Array

Abstract

Channel capacity of a Millimeter(MM) wave cellular network employing phased antenna array (uniform linear antenna array) and the array output signal to noise ratio is analyzed. Millimeter wave as the name indicates working on a very high frequency band 28, 38, and 72 GHz bands results in antenna size in millimeter. Therefore the antennas are integrated on chip and they are also steerable to achieve very high capacity. In millimeter wave directional antennas are used with beam steering to achieve high data rate and high capacity. The data rate increases 40 times more than the off chip or external antennas. In this paper channel capacity is analyzed for a uniform linear array and a planar array antenna structure with beamforming and beamsteering.
