Integrated Antenna Module for 5G Applications

Abstract

This work presents an antenna integrated module operating in the 28 GHz frequency band. The module comprises of a 2x2 antenna array integrated with a beamforming transceiver chip operating in the 24 - 30 GHz range. The beamformer transceiver chip has in total eight transceiver channels and it excites four vertical and four horizontal polarizations in the dual polarized patch antennas array. A maximum EIRP of 35 dBm is achieved with this module in each polarization. The module can be cascaded to form a larger array for base station applications.
