It is known that the connection of the capacitive, inductive or impedance loads into the stub and loop antennas parmits to extend the bandwidth, to correct the directional patterns and to reduce physical dimensions of antennas. However in the publications available for us [1, 2, etc.] only special cases of simple design antennas with loads have been described.
Therefore we had a task to obtain the universal algorithm for the accurate calculation of bent stub and loop antennas of various design with arbitrarily connected lumped power source and impedance loads. The Fredholm's integral equation (IE) of the 1st kind similar to that used by Pocklington exactly one hundred years ago [3] while proving sinusoidal distribution of current in thin conductor was taken as the foundation for this problem solution.
