Enhanced Wide-Angle Steering with Multi-Mode Multi-Port Aperture Antenna Arrays

Tim Hahn, Dirk Manteuffel

A novel concept for wide-angle scanning is proposed based on multi-mode multi-port antennas. The theory of multi-mode multi-port antennas based on aperture radiators is developed a…

A Manifold-Based Framework for Coupling-Aware Surrogate Optimization of Antenna Arrays Using Characteristic Modes

Leonardo Mörlein, Dirk Manteuffel

A surrogate-based synthesis framework for antenna arrays is presented that incorporates mutual coupling while keeping optimization computationally efficient. The method combines a…

On the Relation of Characteristic Modes of Different Conducting Structures

Leonardo Mörlein, Dirk Manteuffel

A formalism is derived to analyze the scattering of a conducting structure based on the characteristic modes of another structure whose surface is a superset of the first structure…

Array Synthesis in Terms of Characteristic Modes and Generalized Scattering Matrices

Leonardo Mörlein, Dirk Manteuffel

The synthesis of antenna arrays in presence of mutual coupling using generalized scattering matrices in terms of characteristic modes is proposed. For the synthesis, the array is b…

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…
