Abstract
The present invention provides a solution to determine a real-time location of an object in an indoor facility utilizing the spatial and angular antenna diversity on a sensor. Specifically, the spatial diversity is achieved by placing a second antenna a predetermined distance (which is greater than one-half of the wavelength) away from the first antenna. The angular diversity is obtained by placing the second antenna at ninety degrees (perpendicular) angle of the first antenna.
