Cognitive beamforming antenna

This paper presents our design of a cognitive beamforming antenna that is capable of reconfiguring its spatial and spectral receiving and transmitting properties in response to the dynamic situations encountered. We accomplish this through joint frequency and spatial scans to establish both spectral and spatial knowledge of the local RF environment. With this information we are able to establish the optimal frequencies and beam patterns to exploit the current environmental situation, including adding beam pattern nulls if required. This design is an effective solution in the common situation where strong interferences and spectral congestion are present that could impact system performance.
