Numerical Integration Techniques Applied to the Analysis of a Short Loaded
Wire Antenna over a Dry Earth
Although simplified cases of antennas in ideal situations are easily solved in
closed form without having to get one's hands dirty, analysis of more complex
cases with antennas in realistic environments requires numerical methods to
approximate the solutions to integral equations in order to produce usable
results. These numerical methods will be used to demonstrate theoretically
that one can control the input admittance, radiation pattern, and gain of
an antenna by loading it with coils.
The experimental verification of these theoretical results will lead up to the
analysis of a loaded wire antenna under the assumption that its length is
much smaller than the signal wavelength. The case for which this short
low-frequency antenna is above a dry earth will be approximated by
analyzing the antenna above a dielectric half-space.
