Abstract
An example ultra-wideband (“UWB”) multiple-input multiple-output (“MIMO”) antenna operating across a continuous, wide-range frequency band can include a ground plane, a wideband monopole antenna arranged over the ground plane, and a ring antenna arranged over the ground plane and around the wideband monopole antenna. The ring antenna can include a plurality of pairs of dipole antennas, where these dipole pairs are configured for symmetric, out-of-phase coupling with the wideband monopole antenna. The wideband monopole antenna and the ring antenna can also be configured to generate respective electric fields having orthogonal polarizations.
