Mobile and Indoor Antennas for Digital Television

Abstract:

Digital Television is an exciting new area of recent technological development in Australia.  A fundamental requirement for Digital Television is the necessity for new antennas for a specific UHF band.  Thus, an interest has been recently renewed in the common analogue television antenna.  Preliminary research has also indicated that gaps in current antenna technologies exist with regard to Digital Television. Revisitation of these designs has led to the study of more intricate antennas for different television reception applications, namely the mobile and indoor antenna designs.

The following thesis provides a detailed analysis of two such antenna designs for specific usage in the Digital Television industry.  A comprehensive discussion of basic theory and design guidelines as well as processes involved in the numerical computation of current distributions has been performed.  Computer-aided design of the wire antennas using EAM:NEC has then been conducted with several design iterations leading to the implementation of two final prototypes.  Measurements of both these prototypes have indicated that a high degree of theoretical and experimental correlation is evident.  Although it has been shown that a majority of the design specifications for both designs have been met, further improvements have been suggested which could lead to the development more accurate designs.
