Abstract


In this paper, a metamaterial inspired antenna to operate in the C-band is designed, fabricated, and characterized. The structure is based on the metamaterial tripolar array, to obtain a better gain, bandwidth, and frequency resonance when compared to a conventional circular UWB antenna with same structural characteristics. Simulation and experimental results show an increase of about 32% on the bandwidth and 9% on the gain with a satisfactory radiation pattern.

Keywords


UWB, patch antennas, metamaterial, FSS.
