Abstract: Techniques for providing radio-frequency signals to a region of interest for a living-objection protection (LOP) system are provided. An example base wireless power transfer system includes a power-coupling element and a power transfer circuitry configured to provide energy to the power-coupling element to produce a magnetic field, and a living-object protection subsystem including an antenna configured to transmit a first radio-frequency (RF) signal with a main beam directed away from the power transfer circuitry and to receive a second RF signal, the antenna including a radiating element and a reflector with the reflector being disposed between the radiating element and the power transfer circuitry and comprising a metal sheet disposed over an area, the metal sheet defining at least one opening within the area and between the radiating element and the power transfer circuitry.
