Abstract
A Planar Inverted-F Wing Antenna (PIFWA) device, system, and method used for commercial and residential induction cooking tops, ovens, combo-steamers, and pressure cookers. The outline of the PIFWA is an isosceles triangle with a truncated vertex end opposite the base side. The PIFWA transmits and receives (TX/RX) signals with wireless sensors including Surface Acoustic Wave (SAW) devices. The antenna comprises a device, system, and method to monitor the cooking process and temperature of food. Embodiments of the PIFWA antenna operate at about 433 MHz, have a feed between two slots, and a shorting plate at the opposing end. Antenna location and alignment within the culinary appliance provides uniform signal strength and gain performance in the regions occupied by one or more sensors.
