Abstract

The work presented in this thesis is part of a larger effort to investigate the use of datacasting for mobile applications. Datacasting is the technology that utilizes the unused bandwidth from digital television as a one-way data channel, and it is currently available over the UHF television band in many regions of the United States. The technology works well in providing high data rate downloads to fixed-location receivers, and the effort documented here describes the development of an antenna to facilitate datacast reception in mobile environments.

To identify antenna designs that would meet the design criteria for a mobile datacast receiver antenna, a modeling study was undertaken to explore various design approaches. That study is the primary topic of this thesis.

In the process of investigating datacast performance, it was discovered that rainfall degraded reception. This unexpected finding has an impact on desired antenna pattern, and it is documented here.
