摘要：
In this work, radiation performance of an antipodal Vivaldi antenna is enhanced using a broadband metasurface lens structure in 1-6 GHz bandwidth. Radiation pattern for the new antenna is more directive due to electromagnetic properties of the metasurface lens. In order to create such a lens, electrically responsive unit cells with high effective permittivity values are utilized. Unit cell dimensions are adjusted to display no resonant behaviour in the designated bandwidth. Overall lens structure is etched over the same substrate containing the antipodal Vivaldi antenna resulting in a compact and low profile design. Far-field radiation patterns indicate a more directive beam is radiated from the modified antenna with metasurface lens. Measurement and simulation results show that directivity is increased considerably without affecting the efficiency characteristics of the antenna due to the inclusion of the metasurface lens.
