A compact polarization diversity ultra-wideband (UWB) antenna with size 32 × 32 mm2 is presented in this paper. The proposed antenna consists of a linear tapered slot (LTS) ground, two orthogonal micro-strip feed lines and a floating fork-shaped decoupling structure located diagonally across the two orthogonal microstrip feed lines. The ground is in one side of the substrate, and the feed lines and the decoupling structure are in the other side. In addition, two rectangular slots are made in both the ground and feed lines to widen impedance bandwidth. Simulated and measured results indicate that the band covers from 3.1 to 12 GHz with S11 < −10 dB and S12 < −15 dB.
