Proceedings ArticleDOI
Digital predistortion of amplitude varying phased array utilising over-the-air combining
TL;DR: It is demonstrated that the array can be linearised over-the-air using single polynomial, and the proposed approach offers an alternative way of re-thinking the concept of array linearisation over multiple PAs.
Proceedings ArticleDOI
Effect of the antenna-human body distance on the antenna matching in UWB WBAN applications
TL;DR: The size of antenna's reactive near-field was satisfied to be an important factor in the evaluation of an acceptable on-body operation and the effect of the antenna-body distance on the antenna operation is analysed in the terms of the matching.
Journal ArticleDOI
Analyzing 5G RF System Performance and Relation to Link Budget for Directive MIMO
TL;DR: This paper addresses system performance boundaries and the analysis method toward multibeam communications at millimeter wave and combines analysis from antennas and propagation to the radio frequency (RF) transceiver specifications and beamforming requirements.
Proceedings ArticleDOI
Measurement-based on-body path loss modelling for UWB WBAN communications

TL;DR: A path loss model for an ultra wideband (UWB) wireless body area network (WBAN) on-body communication is presented and it is shown that the loop antenna outperforms the dipole antenna in respect to the slope of the attenuation.
Journal ArticleDOI
Ultra wideband loop antenna on contact with human body tissues
TL;DR: In this paper, the effect of body tissue thickness on the performance of an ultra wideband (UWB) loop antenna by simulations when the antenna is operated on contact with tissues is analyzed and characterized in terms of reflection coefficient S 11, gain and total antenna efficiency, group delay, radiation patterns and specific absorption rate.
