We show that dispersion characteristics of antenna patterns should be taken into account
when developing systems using UWB signals. The accuracy of measurement of angular …

The problem of obtaining three-dimensional radio images of objects with increased
resolution based on the use of ultra-wide-band pulse signals and new methods of their …

Dispersion properties of the mutual impedance of emitters significantly alter the shape and
spectrum of ultra-wideband (UWB) signals which must be taken into account when forming …

A simplified architecture for a scalable phased array is proposed. In this design, a new
technique for steering the array's beam has been devised. The proposed technique …

This research presents a novel design of a timed antenna array of two‐arm log spiral
antennas. The design consists in optimising the non‐uniform antenna positions in order to …

A new approach for designing scalable phased array architectures with the main goal of
reducing their complexity is proposed. This goal has been accomplished by devising a new …
