Distributed beamforming (DBF) is an efficient technique for reliable communications in
wireless sensor networks (WSNs). In DBF based networks, the randomly distributed nodes …

Beamforming of an adaptive array antenna often becomes effective for the precise
localization of nodes in wireless sensor networks. In an erratic channel, a link with possibly a …

This paper proposes an optimization algorithm to determine the optimal coherent
combination candidates of distributed local beams in a wireless sensor network. The beams …

We present an adaptive approach for synchronizing both the phase and frequency of radio-
frequency transceivers over 90 m wireless links to support distributed antenna array …

The power pattern synthesis, as well as the sidelobe level (SLL) suppression of the planar
antenna arrays for the wireless power transmission is investigated. An improved chicken …

Shaping the distribution of electromagnetic field in a given target area, especially in the case
of inhomogeneous mediums, is an interesting and challenging problem. And the multilayer …

In recent years, there has been an increasing interest in distributed antenna arrays due to
their potential to provide improvements in performance, scalability, robustness, and cost …

Mobile communications and spatial detection require antennas with high directive radiation
pattern. The main aim of this paper is to achieve directive by reducing side lobes for linear …

The goal of this thesis will be to create, develop and adapt beamforming optimization
models aiming to minimize the sidelobe in the Lp-norm sense. An initial model will be …
