UWB near field detection of egg quantity in a fridge: A preliminary study

This paper focuses on a preliminary study to determine the quantity of eggs in a fridge using ultra wideband (UWB) impulse responses in the near field. First of all this paper investigates the detectable positions of an egg when placed 1 cm above a UWB antenna array element. Secondly, one egg with six possible configurations on an array are constructed and coupling information is initially obtained for understanding the effect of egg locations. Reflection coefficient and mutual coupling between elements with a random quantity of eggs are analyzed from which a correlation coefficient is derived and used in a different number of eggs present.
