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.
