An effective procedure for accounting for the mutual coupling between rectangular apertures in the design of nonuniform array antennas is discussed. The central element of the procedure is a two-dimensional interpolation scheme allowing the evaluation of the coupling admittance b

A complete tool for analyzing the mutual coupling in nonuniform (interleaved) array antennas consisting of rectangular aperture radiators is discussed. It relies on deriving the coupling admittances between arbitrarily located apertures via a two-dimensional interpolation scheme.

An experimental method to perform near-field measurement of system-embedded antennas is presented. The proposed approach employs two probe antennas, one fixed and one scanning, enabling to retrieve both amplitude and phase of the near-field. This allows to employ conventional nea

This contribution discusses a near-field antenna setup capable of delivering multiple input signals with controllable (i.e., user defined) amplitude and phase relations to an antenna under test, operating in the X-band. The setup is based on a Cartesian modulation (phase and quad

Wireless applications are now an integral part of everyday life. On the one hand, these applications are being praised for making lives better by facilitating efficient communication and effectively treating disease. On the other hand, they are criticised for invading privacy and

The shared aperture antenna, an effective and versatile radar front-end design strategy based on deploying interleaved sub-arrays on a common aperture, is discussed. A number of instantiations of this concept, demonstrating multi-functionality and polarisation agility capabilitie
