Smart Antenna Technologies(SAT) is a developer of high performance, ultra compact antenna systems. These antenna are typically used in digital appliances such as mobiles, laptops, tablets, connected cars and Internet of Thing Devices.

This is due to some world beating IPR originally developed at the University of Birmingham and further exploited by SAT. If you have an antenna problem that is extremely challenging then SAT are the people to talk to.
