In this paper, a tri-band multi-antenna system, consisting of two pairs of Planar Inverted-F Antenna operating at 1.92-2.17GHz, 2.4-2.485GHz and 2.5-2.7GHz bands and placed on a small ground plane, with high ports to ports isolation is proposed. The proposed isolation solution is based on a specific orientation of these antennas and the insertion of an optimized slot on the ground plane. The diversity performance of the proposed isolated system are calculated and discussed in 1.92-2.17GHz frequency band. The size and performances of this antenna system make it a good candidate for hand-held devices with diversity and/or Multiple Input Multiple Output applications.
