Abstract

Future applications in sensing and communications at (sub)-millimetre wavelengths will benefit from having large integrated coherent arrays. The use of lens arrays will enable the fabrication of integrated antenna front-ends with many potential independent beams as well as dynamic scanning capabilities. For applications such as MIMO communications, interferometric arrays and Tx/Rx duplexing capabilities, a key design parameter can be the mutual coupling between the integrated antenna front-ends. In this contribution we model such mutual coupling for lens antenna arrays using Geometrical Optics technique combined with a bidirectional forward ray-tracing. The validation of the methodology against full wave simulations is also presented here.
