- W2028049216 abstract "There are two reasons. Firstly, despite the problems that the mobile communications industry are currently having as a result of uncertainties of third generation system uptake, it remains one of the most important technology sectors across the world. Secondly, whilst the topic of antenna measurement techniques is a largely mature one, there are significant new challenges thrown up in measuring antennas on mobile terminals. Most antennas used in fixed systems are intended to operate in a single direction. They are thus measured in an anechoic, or reflectionless, chamber or on a special outdoor range that ensures incident energy arrives from a single direction only. When operating a mobile telephone in a built-up area, possibly without a line of sight, a multipath propagation environment occurs with rays from the base station incident from many directions simultaneously. The measurement of the antenna must in some way simulate this environment. The close proximity of the head is a further factor that leads to novel and unique measurement problems both in terms of the characterization of the radiation properties and the measurement of the absorption of energy into body tissues. For these reasons this book is both welcome and timely." @default.
