The aim of this research was to study a novel, broadband, low cost, low profile
and a high-medium gain antenna in the UHF band. This has been achieved through
numerical modelling, theoretical investigation and physical measurements. In this study
two commercially available antenna systems are investigated in order to compare and
establish potential deficiencies in the UHF antenna systems. A number of
disadvantages are resolved within a novel antenna system design. The parametric
study is performed for each element of the novel antenna system in order to optimise its
The indoor and outdoor measurements have been carried out in house, in order
to validate the predicted results. The novel antenna system is compared to the most
popular and commercially available UHF antenna systems. The study demonstrates
that the novel antenna system has clear advantages such as broadband, balanced,
compact and low cost when compared to the commercial antenna designs studied here.
The comparison of the manufacturers’ data to the measured results shows a good
match, validating the outdoor measurements technique used in this research.
