Abstract

"The work presented in this thesis consists of two separate topics. The first topic is a new method for the characterization of radiated susceptibility of electronic devices, while the second topic is on antenna design. The first topic proposes an approach to experimentally determine locations within an electronic system that are well coupled to external far-field radiators. This method is performed by using a differential magnetic field probe to sweep across the target device while measuring the total radiated power (TRP) produced by the device in a mode stirred tent. Scan locations where the TRP is larger than the background level produced by the probe itself are indicative of structures that are well coupled to the far-field. Combining this information with near-field injection susceptibility scans can help designers perform root-cause analysis on radiated susceptibilities. The second topic that is presented in this thesis is the design and optimization of a miniaturized spiral antenna for ultra-wideband applications. In this work, a circularly polarized wide beam antenna that operates in the frequency range from 3.1 to 10.6 GHz and has a very small profile (< 0.5 mm) and size (< 900 ����2), is designed and simulated. This topic also incorporates miniaturization and optimization techniques to ensure the antenna is as small as possible while having acceptable performance (antenna mismatch not worse than -7 dB)"-- Abstract, p. iv
