Multi-band, microstrip patch antennas, as well as methods of fabricating the same and methods of using the same, are provided. A decoupling technique can be used where strategically etched slots are provided between the tightly coupled microstrip patch antennas, and the appropriate mode excitation of the corresponding patch antennas can be used. The antennas have high isolation between the frequency bands of operation. Multi-band operation can be achieved by exciting a different mode on each contiguous portion of the patch antenna.
