Pattern Reconfigurable Antenna with Flowing Liquid Switch

摘要

This paper proposes a new solution for realizing a pattern reconfigurable dielectric resonator antenna (DRA) using liquid injection to the 3D-printed container. The proposed methodology solves the existing problems of PIN-diode type reconfigurable antennas in narrow bandwidth and low radiation efficiency. The proposed DRA successfully demonstrates how to manipulate HEM_(11δ) and TM_(01δ) modes with broadside and conical patterns in two states.
