Vagins is an experimental physicist, but his work relies on a vast complex machine underpinned by an orchestra of subsystems – mechanical, electronic, computational and human – each playing precisely ...

Antenna design is often referred to as a black art or witchcraft, even by those experienced in the space. To that end, [Janne] wondered—could years of honed skill be replaced by bruteforcing the ...

Abstract: This paper presents a novel low-profile, single-layer, differentially-fed microstrip antenna with a flat-top beam (FTB). By incorporating a central hexagonal slot together with four ...

Abstract: Two-dimensional (2D) flat-top beams are of great significance in wireless communication applications. This article presents the analytical synthesis of a 2D flat-top beam on a reflectarray ...

Air Traffic Controllers use Automatic Dependent Surveillance-Broadcast (ADS-B) as an alternative to secondary radar to track aircraft. The ADS-B is transmitted by the aircraft and contains information ...
