Reconfigurable Antenna with Circular Polarization on Dual WiMAX Bands Based On Liquid Metal Switching Capability

In this article, we present a novel reconfigurable antenna with circular polarization on dual WiMAX bands (3.5, 5.8 GHz) based on liquid metal switching capability. The circular polarization reconfiguration is achieved by connecting the rectangular parasitic element (Pc) with the feed line by the liquid metal switch. The mechanism of switching is based on controlling the liquid metal in microfluidic channels by applying a voltage to move and remove the high-conductivity liquid metal EGaIn on the microchannel. The proposed antenna has a simple configuration and compact size that generates dual WiMAX band with Circular polarization (CP) performance by changing the state of the liquid metal switch that is suitable for 5G wireless technology.
