Abstract

The results of decreasing the dimensions of wire antennas to the sizes of smaller resonant ones are considered, which leads to complete mismatch of antennas’ inputs with feeders and to decreased effectiveness. Methods of optimizing and increasing the effectiveness of these electrically small antennas and improving their input characteristics by inserting inductive and capacitive elements at specific points in the breaks of radiating arms of antennas. An example of applying these methods in practical design is provided.
