The next phase of satellite technology is being characterized by a new evolution in non-
geostationary orbit (NGSO) satellites, which conveys exciting new communication …

A review of technological solutions and advances in the framework of a Vertical
Heterogeneous Network (VHetNet) integrating satellite, airborne and terrestrial networks is …

Single beam patterns radiated by linear sources degrade as their maxima points toward
endfire direction. Different source geometries are, therefore, to be investigated and …

Modern society is undergoing a fundamental change in the way we interact with technology.
More and more devices are becoming “smart” by gaining advanced computation capabilities …

During last three decades, the antenna control systems have been extensively developed,
studied and applied in several satellite communication systems. While tracking the signal …

With the development of telecommunications and its applications, the design of compact
antennas with high performances becomes a great necessity. Among the important …

In this article, we propose three-dimensional antenna systems for determining the position of
electromagnetic radiation source at an unknown location. Received signal power at different …

The frequency diverse array (FDA) antenna can generate very directional beams with high
gain that can be steered directly and continuously to track the low earth orbit (LEO) satellite …

The Frequency Diverse Array (FDA) antenna provides range-angle-time dependent
beampattern, potentially generating highly directional beams with high gain that may be …

Electronic beam steering via antenna arrays has the potential of replacing the mechanical
steering at satellite ground stations. In this work, we exploit the benefits of antenna arrays at …
