Apparatuses and methods for making configurable antennas are provided. An apparatus can include a phase change material (PCM) having a conductive phase and an insulating phase. The PCM can be activated to the conductive phase to produce an antenna structure. Different antenna shapes can be created by selectively inducing regions in the PCM to be conductive. Different antenna shapes can be produced having specific resonance frequencies and radiation patterns to suit the application. The PCM phase change can be induced using selective heat application.
