Antennas and Radiation: Network Factors

This lecture covers the concept of network factors in antennas and radiation. Starting with the zero mutual coupling assumption, the instructor explains the calculation of the field radiated by the potential at a distant point. Examples of network factors for different antenna configurations are provided, emphasizing the importance of position and excitation of elements. Linear arrays with linear phase shift and equidistant networks are discussed, highlighting the control and symmetry in radiation patterns. The lecture concludes with the significance of relative field values and the use of imaginary values in antenna design.
