Notes:
We present a new concept for compact, tunable antennas. Traditional approaches havecircuits and switchable elements which can be bulky and lossy. Here we investigate structureswhich offer direct tuning through voltage-controlled deformation of the radiating structure itself.The antenna is a dielectric resonator (DRA), where the antenna impedance and tuning depends onthe shape of the dielectric. The deformation action is through using electro-active polymer (EAP)for the dielectric. EAPs have promising properties for smart antennas and ongoing developmentsare continuing to improve its suitability
