Microstrip Antenna: What is Low Profile?

[tensorbundle]

I found in many sources describing microstrip antennas are 'low profile'. Well, I know several antenna parameters like radiation pattern, antenna gain, intensity, directivity etc. But what is this 'low profile'?? Can anyone tell me what sort of property of an antenna does the term 'low profile' indicate? Thanks in advance.

I'm pretty sure "low profile" refers to the physical shape of the antenna.

From http://en.wikipedia.org/wiki/Microstrip_antenna:

A [microstrip] antenna is a narrowband, wide-beam antenna fabricated by etching the antenna element pattern in metal trace bonded to an insulating dielectric substrate [...]
