Classification: CPC H  G | IPC G  H

Claim 12:
13. A method for determining user intent to access a secure area, the method comprising:
receiving an ultra-wide band (UWB) signal from a credential device at each of a first and second UWB antenna in a UWB antenna configuration, the UWB antenna configuration comprising:
the first antenna;
the second antenna; and
a material disposed between the first and second antenna and having a thickness that defines a distance between the first and second antennas of less than a half wavelength of the UWB signal through air (λA/2), the material configured to slow down electromagnetic waves passing therethrough such that the thickness of the material provides an effective separation distance of the first and second antennas of at least a half wavelength of the UWB signal through air (λA/2); and

determining localization data relating to the credential device based on the UWB signal.
