Abstract : With the dawn of the Digital Battlefield, a critical capability in the modern warfare environment is the miniaturization of electronic warfare signal and information processing systems. To realize such systems, the key is to miniaturize antennas that transmit and receive signals. In particular, by introducing reconfigurable antennas, one can combine multiple antennas operating at various frequency bands into a single aperture, which can provide significant miniaturization and flexibility to the entire system. To design such miniaturized antennas, new materials and technologies have to be incorporated. For this purpose, the PI has designed and demonstrated miniaturized antennas by introducing metamaterials such as split ring resonators (SRRs) into the antenna structure. Also proposed and designed were conformal antenna structures with in-plane SRRs for the convenience of integration. In addition, by introducing phototransistors into the SRRs, a frequency tunable antenna was designed. This small reconfigurable planar antenna could be integrated into an Army platform to miniaturize the size of the system while providing additional functionality.
