Abstract

In this letter, a novel frequency reconfigurable antenna with the aid of liquid metal is presented. The proposed antenna incorporates a 3D-printed fluidic channel, which is placed cross to the metallized part of radiator. Compared to general meandered channels, the proposed cross placed fluidic channel ensures less liquid metal to be consumed, whilst it achieves the same capability of frequency reconfiguration as a solid patch. More importantly, it allows the proposed antenna to have a promised total efficiency thorough its switchable frequencies. The proposed antenna can switch among 2.1 GHz, 2.6 GHz, 4.4 GHz, and 11 GHz, enabling it to be adopted in various applications.
