Abstract
A tunable antenna structure including a substrate and at least one radiating element configured on the substrate. The antenna structure further includes a plurality of nanomaterial-based phase changing material (PCM) switches configured in the radiating element so that current flowing through the radiating element passes through the PCM switches. The antenna structure also includes a heating device, such as a laser or a resistive heater, configured relative to the PCM switches and being operable to selectively heat the PCM switches to switch the PCM switches between an on crystalline state and an off amorphous state, where once the heat is removed, the PCM switch remains in the particular state.
