During the past several decades, the multimode resonator (MMR) technique has been
extensively investigated and widely used, with successful exploration of a variety of high …

This article, as part of the special issue on characteristic modes (CMs), updates the recent
progress in develo** advanced multiple antenna systems based on CM analysis (CMA) …

A multitude of autonomous robotic platforms collectively organized as a swarm attracts
increasing attention for remote sensing and exploration tasks. A navigation system is …

The DoA of radio waves is used for many applications, eg the localization of autonomous
robots and smart vehicles. Estimating the DoA is possible with a multiport antenna, eg an …

Improving safety is of general interest in aviation. Flight transponders used in collision
avoidance systems advise pilots with information of potential collisions and avoidance …

A deterministic evaluation procedure for multiport direction-finding (DF) antennas is
proposed. It is based on a DF uncertainty parameter, which describes how well different …

Joint communication and sensing (JCAS) is of special interest due to densification in various
contexts like wireless networks, airspace, and transportation networks. In this paper, a JCAS …

Autonomous robotic swarms have attracted increasing attention in recent years due to their
enormous, principally unlimited, capability expansion from single robot systems. A …

This work proposes compact multimode Multiple-Input–Multiple-Output (MIMO) antennas for
Angle of Arrival (AoA) estimation in miniaturized Internet of Things (IoT) systems. The …

Cooperative radio localization and navigation systems can be used in scenarios where the
reception of global navigation satellite system (GNSS) signals is not possible or impaired …
