Abstract

This paper presents design of 5G multiple input multiple output (MIMO) antenna for 5th generation (5G) base stations. The proposed antenna is dual band and it operates at millimeter-wave (mm-wave) frequencies 28 GHz and 38 GHz. It is also dual-polarized and it can switch between vertical and horizontal polarizations. The sub-array is formed of four gap-coupled microstrip slotted dual-band patch antennas with corporate microstrip feed network. The sub-array exhibits realized gain greater than 12 dBi at 28 GHz and 38 GHz and 10-dB bandwidth of around 1 GHz at 28 GHz and 38 GHz. The antenna sub-arrays are arranged on the sides of an octagonal prism to synthesize multi-beam radiation patterns with twelve sub-arrays distributed on each side of the prism. The proposed antenna has the capability of steering the pattern to particular directions by switching between antenna sub-arrays placed on either side of the prism. The proposed antenna is a good candidate for 5G base stations as it achieves polarization and pattern diversity and fulfills 5G system requirements in terms of high gain, adequate bandwidth, MIMO configuration and fixed beam-switching capability.
