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.

Decoupled multi-band microstrip patch antennas

Multiple-input-multiple-output (MIMO) antenna devices and methods of using and fabricating the same are provided. A MIMO antenna device can include a plurality of substrates each having an antenna element. The substrates can be provided in connected series and can be attached to a framework. The substrates can have alternating style antenna elements, such that a first substrate can have a straight-fed patch and a second substrate adjacent to the first substrate can have a bent-fed patch and a third substrate adjacent to the second substrate, and on an opposite side of the second substrate than the first substrate is, can have a straight-fed patch and so on.

A MIMO antenna device can include a plurality of substrates each having an antenna element. The substrates can be provided in connected series and can be attached to a framework. The substrates can have alternating style antenna elements, such that a first substrate can have a straight-fed dipole and a second substrate adjacent to the first substrate can have a bent-fed dipole and a third substrate adjacent to the second substrate, and on an opposite side of the second substrate than the first substrate is, can have a straight-fed dipole and so on.
