Abstract
A calorie estimating device for measuring a calorie content of a food item is provided. The device comprises a holder substrate, a transmitter antenna configured to transmit ultra-wide band (UWB) signals to at least a portion of the food item disposed on a side of the holder substrate, wherein the transmitter antenna comprises a planar antenna, a first receiver antenna configured to receive at least a portion of UWB signals reflected by the food item, wherein the first receiver antenna comprises a planar antenna, and a second receiver antenna configured to receive at least a portion of UWB signals propagated through the food item, wherein the second receiver antenna comprises a planar antenna.
