Abstract :
This paper introduces some baseline results of dielectric loaded antennas that would be potential for meeting high data rate specifications for future communication systems. The generalized eigenfunction method applied earlier to diffraction problems and in laser theory can help to find within a reasonably limited amount of calculation not only static but dynamic characteristics of antennas. The dynamic analysis is important for estimation of the maximum information rate which can be transmitted through the antenna without distortion. Examples of dynamic changes in antenna pattern and in input impedance for different cylindrical dielectric antennas with a step excitation are presented.
