Sažetak
The intrinsic frequency dispersion has been usually considered as a relevant drawback of metamaterials, limiting their application to narrowband microwave components. However, it has been recently demonstrated that a particular metamaterial-based lens, consisting of a combination of an epsilon-near-zero (ENZ) material and air, is able to enhance the gain of short horn antennas over a broad frequency range. This interesting result has been achieved by exploiting the dispersive nature of ENZ metamaterials. In this contribution, we further discuss the latter aspect, giving more details about the physical mechanism enabling broadband operation of shortened horns loaded with ENZ-air lenses. The discussion is supported by a set of experimental results obtained on a fabricated prototype.
