Design of Dual-Band Millimeter-Wave Antenna Array for 5G Communication System

摘要

In this paper, a dual-band millimeter-wave antenna array is proposed. The dual-band antenna consists of a monopole branch and a patch that are printed on a cavity-backed ceramic block. The first resonance is generated by the coupling between the monopole and the patch, and the second resonance is generated by the monopole. The antenna can be mounted on the PCB. Simulated antenna return loss indicates that the proposed antenna can meet the requirements of the two potential Chinese fifth generation(5G) millimeter-wave bands (26GHz and 40GHz). And the beam scanning performance of an eight-element antenna linear array is presented for the above two bands.
