Dual-band antenna array with beam steering for mm-waves 5G networks

Abstract

This work reports an innovative structure and preliminary results of a four-elements antenna array with beam steering for 5G access cellular networks, operating in the underutilized millimetre wave (mm-wave) frequency spectrum. Its structure is based on four slotted-waveguide antenna arrays, which enables to simultaneously perform radiation pattern reconfiguration in the 28 GHz and 38 GHz bands, providing scanning range of 75° and 55° for the lower and higher frequency bands, respectively. The bandwidth varies from 24.19 GHz to 31.42GHz and from 36.61 GHz to 39.22GHz.
