A system for measuring a temperature of a food in an oven includes an energy emitting antenna positioned in the oven proximate an oven cavity and a battery-free sensor probe configured to be inserted into the food in the oven cavity. The energy emitting antenna sends a plurality of first signals at a same frequency that are phase shifted relative to each other. The battery-free sensor probe has a sensor probe antenna harvesting energy transmitted from the energy emitting antenna and transmitting a plurality of second signals back to the energy emitting antenna. The first signals are steered by the phase shifting to ensure that the first signals are received by the sensor probe antenna.
