Microwave aperture antennas using nanomaterials

In this paper, computer simulations are used to investigate the concept of designing microwave aperture antennas, potentially fabricated using metallic nanomaterials. Nanomaterials are considered as they facilitate fabrication and electromagnetic advantages. Aperture radiating structures have been excited by a plane wave in a microstrip line. The aperture was modified with the addition of fine scale structures; vertical strips shorter than the height of the aperture. These initial simulation results have shown that these fine structures inside the aperture can decrease the resonance frequency at the expense of the bandwidth.
