Antenna and Arrays: Arrays

This lecture covers linear antennas, uniform linear antennas, phased linear antennas, interference, superdirective antennas, cosine weighting, linear arrays, arrays of directive sources, delay and sum beamforming. It explains the concept of uniform linear arrays and phased linear arrays, discussing the directivity and orientation of lobes. The lecture also explores arrays of directive sources, illustrating how the array directivity is derived by multiplying the directivities of the array and each directive source. Additionally, it delves into delay and sum beamforming, showcasing beampatterns of a beamformer composed of two microphones spaced at different distances.
