(Johann Wilhelm) Nel, Mariesa Double ridge guide horn antenna Complex antenna transfer function Time domain Frequency domain Compact antenna test range Anechoic chamber Standard antenna Uncertainties UCTD Dissertation (MEng)--University of Pretoria, 2013. Ultra wideband (UWB) technology plays a significant role in wireless communication. The complex antenna transfer function (CATF) of an UWB antenna provides important information required for better channel designs and communication systems. In this dissertation the CATF of a Double ridge guide horn (DRGH) antenna is determined and used as a standard antenna for UWB measurements. Two methods were used: the two antenna method in an anechoic chamber and a modified gain-transfer method in a compact antenna test range (CATR). Measurements were performed with a vector network analyser (VNA) in the frequency domain, in the anechoic chamber and the CATR. The distance measurements required to calculate the CATF from the S-parameter measurements were performed in the time domain. The CATF of the standard antenna was determined using two identical antennas and then it was shown that a modified gain-transfer method can be used to determine the CATF of any unknown antenna in a CATR, using the standard antenna as a reference. Some of the challenges were to obtain the correct equations and measurement method to obtain the CATF in a CATR. The standard antenna was used to investigate uncertainty contributions for the measurements in the CATR. gm2014 Electrical, Electronic and Computer Engineering unrestricted 2014-02-11T05:15:17Z 2014-02-11T05:15:17Z 2013-09-04 2013 Dissertation Nel, M 2013, A Wideband double ridge guide horn antenna as complex antenna transfer function standard, MEng dissertation, University of Pretoria, Pretoria, viewed yymmdd <http://hdl.handle.net/2263/33373> E13/9/1019/gm http://hdl.handle.net/2263/33373 en © 2013 University of Pretoria.
