Abstract:
The recent emergence of a new class of engineered materials that have electromagnetic properties not typically found in nature, known as “metamaterials”, has generated significant interest within the engineering and physics communities. Specifically, metamaterials that exhibit a negative index
of refraction have received considerable attention for their potential to create novel electromagnetic structures, such as antennas and RF/microwave devices, which exhibit new phenomena and/or demonstrate superior qualities compared to their conventional counterparts
This presentation will focus on the transmission-line (TL) approach to synthesizing negative-refractive-index (NRI) metamaterials, which relies on loading a conventional microwave transmission line with lumped-element series capacitors and shunt inductors. This enables the creation of materials with low losses, which exhibit a negative refractive index over a large bandwidth. Additionally, the compact, broadband and planar nature of the NRITL metamaterials allows them to be easily integrated with other circuits and devices, while significantly improving key performance characteristics. Various metamaterial-based antennas and devices will be presented, including active and passive realizations of components typically found in RF front-end systems. Particular emphasis will be placed on compact and multi-band metamaterial antennas for use in next-generation wireless communication systems, including emerging multi-antenna multiple-input, multiple-output (MIMO) systems for mobile devices.
