Compact Slot Antenna Array for 5G Communications

The need for larger bandwidths led the 5G to move to the frequencies in the millimeter wave bands. New challenges are posed to allow high gain antennas with considerable bandwidths to be used in both sensors and larger arrays. In this paper we present a four-element low profile microstrip slot antenna array, designed for 28GHz, which covers the 5G frequencies, exhibiting more than 9.5dBi of gain. This compact antenna can be integrated into a 5G system.
