Abstract :
For a radiating linear antenna, the loading of 
appropriate impedances at specified locations can lead to: 1) producing desired currents at specified points along the antenna, 2) producing desired radiation fields in specified directions, 3) maintaining desired input impedances at different frequencies, or 4) any linear combination of cases 1), 2), and 3). With pure reactive loadings, only 
values of antenna characteristics can be specified. A method was developed to solve the nonlinear equations in the analysis.
