Time-Modulated Antenna Array for Shaped Beam Patterns in Wideband 5G Applications

Abstract

This paper describes the design of a time-modulated antenna array for shaped-beam patterns in wideband 5G applications. The array is formed by eight disk-notch patch antennas in a linear topology. The antennas are fed with random distributions of switching time sequences and phases. The design process is carried out by the bacterial foraging optimization. The simulation results show the good performance of the array for providing shaped-beam patterns from 3.4 GHz to 4.2 GHz. The shaped-beam patterns generate side lobe level and side band level reductions within the wideband frequency range.
