For the validation of body worn antennas, the human body should be taken into account as the performance of such antennas is likely to differ from their free space equivalents. How best to determine the human body effects on antenna performance is a pertinent point in which many questions still remain. In this paper we consider the efficiency of some newly developed textile antennas for on-body applications...
This paper introduces a novel modification to the design of mechanical stirring paddles in reverberation chambers. The work focuses on lower modal densities with a view to increasing the overall effectiveness of the mechanical stirring operation in this range from a statistical perspective. The research indicates that by cutting tapered slots into the stirrer plate, the induced surface current can...
Planar Inverted F Antennas (PIFAs) are commonly used in portable applications due to their attractive features. There exists a huge demand to use these PIFAs as MIMO or diversity antennas to allow for an increase in data rates or signal quality and to combat the shallow fading minima that exist in a multipath propagation environment with a non line of sight path. Recently, two new single element dual...
This paper deals with the problem of the optimized stirrer design for a reverberation chamber which is becoming popular tool within the EMC and related areas. A new and a conventional stirrers are designed and made for a reverberation chamber of dimensions of 5.8 m times 3.6 m times 3.4 m. Comparisons for these two designs are made in terms of the field uniformity and lowest usable frequency (LUF)...
