Abstract

To eliminate microwave reflections from a truncated-cone antenna element used to irradiate liquid objects with microwaves, the element needs to be designed optimally. Three design parameters were used in the optimization, the objective function to be minimized being power reflection coefficient of the microwaves. An applicable range of relative permittivity for the liquid objects was identified. The characteristics of the antenna were checked in experiments using water. Also the temperature dependency of the antenna was checked in both numerical and experimental tests.
