Abstract :
The paper presents a cognitive antenna based on the self-structuring antenna (SSA) technology that dynamically alters its aperture to maximize signal-to-noise-ratio (SNR) in varying RF environments. A polarization-diversity antenna, which is a simple implementation of the SSA, has been built and tested for Wi-Fi applications. The low profile prototype uses self-structuring feed and has proved effective in improving signal strength and data rates, and is compatible with MIMO implementation.
