This paper presents a compact sensor system for estimating the dielectric properties of materials based on commercial, off-the-shelf (COTS) modules. The dielectric constant and conductivity of a material under test can be determined from the measurem

Radiation pattern subtraction is a useful technique for narrowing a receiving antenna's radiation pattern in a short-distance, non-destructive sensor. The sensor's antenna was developed to be compact and light-weight as well as to operate in real-tim

Approximated models of electromagnetic waves scattered from a sphere with two different dielectric layers were developed and reported in this paper. We proposed that the dielectric properties of a concentric dielectric sphere object, for example, som

This work illustrates the benefit of subtracted beam antenna we presented earlier for a sensor system in fruit pre-harvesting. The angular resolution pattern of a receiving antenna that shows how far the unwanted object (fruit) can be eliminated from

In this paper, a pattern reconfigurable antenna which can be switched between sum and difference (SUM and DIF) beams in E-plane is proposed. Based on the beam switching, a narrow radiation pattern antenna is achieved by subtracting the DIF pattern fr
