Gerber, Monique UCTD DRGH Antenna ElectroMagnetic compatibility (EMC) Ridge profile Impedance taper Ridge with water Dissertation (MEng (Electronic Engineering))--University of Pretoria, 2018. Double Ridge Gain Horn (DRGH) antennas are used widely in test facilities for gain standards and source antennas, more specifically in ElectroMagnetic Compatibility (EMC) testing. The capability of the DRGH antenna to obtain a relatively constant 3 dB and 10 dB beamwidth, within the operating frequency band of 1-18 GHz, deems it appropriate for these applications. The ridges form an essential part of the DRGH antenna and are selected to focus on during this investigation. It was hypothesised that by changing both the profile and width of the ridges across the axial length of the DRGH antenna will improve the gain and beamwidth performance. The starting point was determined by selecting a DRGH antenna that adhered to the EMC requirements. An accurate numerical model was developed of the 1-18 GHz DRGH antenna and used as the box dimensions. The ridges were then improved by implementing the elliptical profile and tapering out the width linearly. Based on the results observed of the prototype DRGH antenna developed the hypothesis was confirmed with the improved ridges implemented.
