ABSTRACT

A microwave bench operating within X-band frequency range 8.2-12.4 GHz is tuned to a desired constant frequency. Dielectric constant (e’) and dielectric loss (e’’) of coconut oil are measured at four different constant frequencies, with varying temperature. The dielectric constant (e’) of coconut oil decreases with increase in frequency, while dielectric loss (e”) increases with increase in frequency. The dielectric constant (e’) of coconut oil decreases with increase in temperature while the dielectric loss (e”) increases with increase in temperature. The dielectric constant and dielectric loss of coconut oil samples are in good agreement with results reported by other researchers.

Keywords: Dielectric constant, dielectric loss, coconut oil
