Abstract
An electronic lock system including an access control device configured to provide system instructions, an interface module electrically coupled to the access control device and configured to transmit RF signals in response to system instructions received from the access control device, and a plurality of wireless electronic door locks each configured to wirelessly communicate with the interface module. Each of the wireless electronic door locks includes a controller and a wireless receiver operatively connected to the controller, the wireless receiver including a first antenna defined as a circuit board trace and a second antenna, spaced from the first antenna and defined as a circuit board trace. Each of the first antenna and the second antenna include one of a monopole antenna and a fractal antenna. The controller is configured to switch between the first antenna and the second antenna to receive a wireless signal having a greater signal strength.
