A single feed multiple band planar antenna is provided. The planar antenna
includes a radiating plate having a first end and a second end opposite
the first end residing in spaced apart relating to a ground plane. A
shorting post couples the radiating element to the ground plane and a
feeding post couples the radiating plate to radio frequency power. The
planar antenna further includes a second radiating plate having a first
end and a second end where the first end of the second radiating plate
coupled to the feeding post and substantially aligned with the first end
of the first radiating plate and located between the first radiating
plate and the ground plane.
