20 GHz-23 GHz Antenna with Tri-State Output Beam-Steering using Fluidic Lens
A fluidically reconfigurable lensed antenna is reported that covers 20 GHz to 23 GHz. The antenna is a modified antipodal Vivaldi antenna element with a fluidically-loaded dielectric lens to facilitate single-element beam-steering for three discrete beam-steering states. The fluid used in this work is ethyl acetate (C4H8O2) with $\epsilon_{r}=6.0+j0.059,\ \tan\delta=0.35$ at 2.4 GHz. The antenna element and lens are fabricated using a substrate with $\epsilon_{r}=3.55$ and $\tan\delta=0.0027$. Experimental results show that the antenna can produce up to 30° of beam-steering across the band.
