Lecture
This lecture covers the principles of linear antennas, including uniform and phased linear antennas, interference microphones, superdirective antennas, and cosine weighting. It explains the concept of linear arrays, phased arrays, and arrays of directive sources, as well as delay and sum beamforming techniques. The lecture delves into the radiation patterns of linear antennas, the properties of uniform linear arrays, and the control of main lobes in phased linear antennas. It also discusses the use of interference microphones in the film and radio industry, detailing the concept of accumulation of infinitesimal plane waves and the output voltage of the microphone.
