A thesis submitted to the Faculty of Engineering. University of the Witwatersrand. Johannesburg in fulfilment of the requirements for the degree of Doctor of Philosophy. / The general argument of the thesis is that the design of broadband antennas demands a thorough understanding of the factors influencing the current distribution on antenna wires. Specifically. current distribution concepts are used to improve the evaluation and design of small broadband antennas for the high frequency (HF) 2 to 30 MHz range. The current distribution on an antenna governs its input impedance, radiation efficiency and radiation patterns. (Abbreviation abstract) / Andrew Chakane 2018

The tremendous growth in broadband communication services, brought about by the phenomenal expansion of the Internet, has triggered an unprecedented demand for bandwidth in telecommunication networks. Optical fibre communication technology has kept up with the growing bandwidth demand by exploiting wavelength division multiplexing (WDM) technology. WDM is now beginning to expand from a network core technology towards the metropolitan and access networks with the goal of bringing the benefit of cost and network efficiencies of the optical networking revolution to the end users. The advent of metropolitan WDM networks has motivated the work in this thesis to develop new devices and design methods in order to reduce cost and improve network performance.
