A Cupola-Shaped Multimode Multiport Antenna for Aerial Direction Finding
Lukas Grundmann, Marc Gerlach, Wolfgang Schäfer +1
A multimode multiport antenna (MPA), constisting of a single conducting structure, is proposed for use with the airborne collision avoidance system (ACAS). Its cupola-shaped su…
Examination Minutes Measurement of Single-Antenna-Element Beamforming
Nils L. Johannsen, Lukas Grundmann
This document shall provide all knowledge gained in conjunction and preparation with the conducted measurements in the antenna measurement chamber of the Institute of Microwave and…
Deriving Characteristic Mode Eigenvalue Behavior Using Subduction of Group Representations
Lukas Grundmann, Lukas Warkentin, Dirk Manteuffel
A method to derive features of modal eigenvalue traces from known and understood solutions is proposed. It utilizes the concept of subduction from point group theory to obtain the…
Evaluation Method and Design Guidance for Direction Finding Antenna Systems
Lukas Grundmann, Dirk Manteuffel
A deterministic evaluation procedure for multi-port direction finding antennas is proposed. It is based on a direction finding uncertainty parameter, which describes how well diffe…
Joint Communication, Sensing and Localization for Airborne Applications
Nils L. Johannsen, Max Schurwanz, Lukas Grundmann +3
With the upcoming trends in autonomous driving and urban air mobility, the number of self-navigating vehicles will increase, since they are foreseen for deliveries as well as auton…
Antenna Optimization for WBAN Based on Spherical Wave Functions De-Embedding
Lukas Berkelmann, Hendrik Jäschke, Leonardo Mörlein +2
Antennas for wireless body area networks (WBAN) need to be modeled with adapted methods because the coupling with the body tissue does not allow for a clear separation between ante…
