WANET (wireless ad hoc network) is expected to be deployed in a wide range of civil and
military applications. The communicating nodes in these networks might be distributed …

In order to estimate the signal parameters accurately for mobile systems, it is necessary to
estimate a system's propagation characteristics through a medium. Propagation analysis …

This chapter presents the practical application of low‐cost printed‐circuit frequency‐
scanning antennas for efficient wireless networks with smart functionalities. The design …

Time-modulation (TM) in four-dimensional (4-D) arrays is implemented by using a set of
radio-frequency switches in the beam forming network to modulate, by means of periodic …

This book provides an introduction to narrowband array signal processing, classical and
subspace-based direction of arrival (DOA) estimation with an extensive discussion on …

This thesis presents a novel concept for focusing an antenna beam pattern as a function of
range, time, and angle. In conventional phased arrays, beam steering is achieved by …

Indoor radio frequency positioning systems enable a broad range of location aware
applications. However, the localization accuracy is often impaired by Non-Line-Of-Sight …

An optical phased array of nanoantenna fabricated in a CMOS compatible silicon photonics
process is presented. The optical phased array is fed by low loss silicon waveguides with …

<? Pub Dtl=""?> A source signal will be subject to different amounts of time-delay as well as
attenuation when it reaches a number of spatially separated sensors. Both time-delay and …

The beam pattern of an antenna array is one of the most important characteristics of
classical phased arrays and of more modern smart antenna, digital beamforming and …
