Dependent claims

An electronic lock configured to be secured to a door having a secure side and an unsecure side, the electronic lock comprising:

an exterior escutcheon on the unsecure side of the door;
an interior escutcheon on the secure side of the door;
a printed circuit board assembly (PCBA) positioned within the exterior escutcheon;
and
a plurality of ultra wideband (UWB) antennas secured to an exterior-facing side of the PCBA, wherein the plurality of UWB antennas comprises a first UWB antenna and a second UWB antenna configured to operate on a first UWB channel, and wherein the second UWB antenna is positioned no greater than one half of a wavelength of the first UWB channel from the first UWB antenna along a first axis.

2 more elements

An access control device, comprising:

a lock mechanism adapted to control access to a passageway;
a printed circuit board assembly having a first side and a second side;
a first ultra wideband antenna secured to the first side of the printed circuit board assembly and configured to operate on a first ultra wideband channel;
a second ultra wideband antenna secured to the first side of the printed circuit board assembly no greater than one half of a wavelength of the first ultra wideband channel from the first ultra wideband antenna along a first axis and configured to operate on a first ultra wideband channel;
an exterior escutcheon adapted to be secured to an unsecure side of a door and to house the printed circuit board assembly;
a processor;
and
a memory comprising a plurality of instructions stored thereon that, in response to execution by the processor, causes the access control device to determine whether a user intends to access the passageway based on signals received by the first ultra wideband antenna and the second ultra wideband antenna from a mobile device of the user.
