Claim:
1. An ultra-wideband (“UWB”) multiple-input multiple-output (“MIMO”) antenna for use across a continuous, wide-range frequency band, comprising: 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 including a plurality of pairs of dipole antennas, wherein respective dipole antennas of each of the pairs of dipole antennas are configured for symmetrical, out-of-phase coupling with the wideband monopole antenna, wherein the wideband monopole antenna and the ring antenna are configured to generate respective electric fields having orthogonal polarizations, wherein the ring antenna is approximately square-shaped, wherein each of the respective dipole antennas comprises a plurality of conductive arms extending in opposite directions from an excitation point, wherein each of the conductive arms comprises a plurality of conductive patches, and wherein one or more coupling slits are arranged between the conductive patches of each of the conductive arms.
