Abstract
Standard gain horn antennas are widely used in electromagnetic compatibility (EMC) testing and antenna measurements. In EMC testing, it is often required to generate high electric field intensities across a wide frequency range within the near-field region. However, the focusing properties of antennas are deteriorated in the radiating near-field region. In order to increase engineering confidence in EMC testing, it is desirable to understand the root causes of the aforementioned radiation degradation. In this thesis, the near-field characteristics of three different pyramidal standard gain horns are investigated using full-wave analysis, analytical methods, and measurement. The causes of near-field gain reduction are examined, as well as the accuracy of a commonly used analytical gain approximation for different horns. The main goal is to develop a process to estimate the near-field gain of horn antennas through various methods as well as foster deeper insight into the near-field behavior of horn antennas.
