SYSTEMS AND METHODS FOR NON-DESTRUCTIVELY MEASURING CALORIE CONTENTS OF FOOD ITEMS
First Claim
1. A calorie estimating device for measuring a calorie content of a food item, comprising:
- 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.
