We present a new technique for designing a dual-band patch antenna with closely spaced bands of operation, whose response can be changed dynamically using a fluidic tuning mechanism. Using this technique, a dual-band tunable patch antenna operating at around 2.5 GHz is designed and fabricated using 3-D printing. Two oil-filled channels are placed in the substrate of the antenna along the nonradiating...

Using this technique, a dual-band patch antenna operating at 2.5 GHz is designed. Two oil-filled channels are placed in the substrate of the antenna along the non- radiating edges of the patch antenna and filled with liquid (or solid) metal cylinders. As the cylinders...
