Abstract: A multiport planar antenna system with digital reconfigurability to adjust a beam-steering function of the system is described herein. A substrate is provided and a grid of parasitic elements is printed on a surface of the substrate. One or more driven, radiating elements such as monopole or dipole antennas are printed on the substrate proximate the parasitic elements. Switching elements between adjacent parasitic elements are then configured to steer the radiation direction in a particular direction in the azimuth plane. The small form factor of the planar antenna system can be used in a multiple-input, multiple-output (MIMO) application used by fifth generation (5G) devices such as mobile phones, internet of things (IoT) devices, and vehicles.

Abstract: Generalized non-limiting embodiments include employing a dipole antenna and/or a half slot antenna. Each of the antennas constitutes three mutually perpendicular radiating elements to achieve good isolation and low antenna signal correlation between the three ports. In one generalized non-limiting embodiment the antennas are fabricated on FR-4 epoxy boards. Experimental results show that the antennas resonate a reasonable frequency and have a desired mutual coupling. In addition experimental results for the diversity performance and the MIMO channel capacity are also provided for these antennas and these results show that the herein described antennas offer good diversity gain and the channel capacity can be increased by as much as three times by using these antennas over conventional antennas.
