The Square Kilometer Array radio astronomy telescope will achieve the majority of
its extremely large aperture area with thousands of parabolic dishes, each illuminated by a wideband antenna feed, and this thesis introduces a new such antenna. The wide bandwidth of this new antenna is achieved with the development of a directional log periodic antenna. Scaling the log periodic elements into three-dimensional space is the
present method used for directional log periodic antennas. We propose confining these
often complex log periodic elements into a single plane, while the ground "plane" takes
on a three dimensional form, permitting low-cost implementations without requiring
the introduction of a complicated scaffolding to support the log periodic elements in 3-D. This low-cost solution would scale well in the implementation of the thousands of antenna feeds that the Square Kilometer Array demands. We also introduce a previously unreported LP design: the log periodic log spiral antenna.
