Angular Localization of Wideband Sources using a single port metamaterial receive Antenna

Indoor source localization becomes a major challenge for many applications such as beam-steering or MIMO communication. We propose to design a single port Rx antenna based on metamaterial dedicated to angular localization of a wideband source. We take the benefit of the strong frequency dependence of the radiation pattern of an open balanced Composite-Right-Left-Hand structure to design the proposed antenna. We experimentally demonstrate with a microwave prototype that an efficient angular localization can be achieved with this approach.
